I am looking for a way to log when USB devices are plugged in and unplugged from a Windows 7 machine. I would like it to function similarly to the USBLogView program made by NirSoft, however we are not allowed to use any third party software on this machine, only first party Microsoft. Basically, if it could log the name of the usb device and the time it was plugged/unplugged that would be perfect.
Edit: sorry batch is not a requisite, to be honest I'm not too familiar with scripting on windows, I'm much more familiar with bash scripting.
Take a look in this solution:
https://superuser.com/questions/1096887/where-can-i-find-logs-on-recent-usb-insertion-in-the-event-viewer (scottschlaefli answer)
Link found on the above answer:
https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/how-to-capture-a-usb-event-trace
This way you'll get a extensive log of all USB devices, than later you can get this log with a software, ex: c# software with 'EventLogQuery' object to get informations and use it.
I'm new with NodeMCU firmware use. I have a Amica ESP-12E (v2?) dev kit connected to a DHT22 which I program using the Arduino IDE. All is setup and working fine.
My problem came when I wanted to update NodeMCU firmware. Since I don't really know what came pre installed from China, I downloaded ESPlorer to try to determine NodeMCU version. I get the following "error" when I reset the dev board:
Communication with MCU..Got answer! Communication with MCU established.
AutoDetect firmware...
Can't autodetect firmware, because proper answer not received (may be unknown firmware).
Please, reset module or continue.
{{a long string of weird characters that I can't copy and paste appear here}}
At this point I'm totally clueless about what version of firmware I have. Is there a way to obtain NodeMCU firmware version by software via Arduino IDE code, ESPlorer GUI or something similar?
On the other hand, is there a really easy way to compile/download latest NodeMCU firmware BIN file? Even one with all the modules active will be fine for me now, I'm just trying to understand and test things.
You seem to be confusing two very different platforms. I leave out some details as not to confuse you any further.
Arduino: you use Arduino programming in the Arduino IDE then build and install a binary to your device whenever the application changes. No NodeMCU firmware needed!
NodeMCU: you flash the NodeMCU firmware once (e.g. using esptool.py) and then upload Lua code (e.g. using ESPlorer) whenever the application changes. This is more lightweight than the Arduino platform.
On the other hand, is there a really easy way to compile/download
latest NodeMCU firmware BIN file?
Yes, have a look at the NodeMCU documentation at http://nodemcu.readthedocs.io/en/latest/en/build/. The easiest is to use the cloud builder at https://nodemcu-build.com/. I currently suggest to build from the dev branch because flashing is easier with it.
As pointed out you have several options for firmware and you'll need to make a choice as to which suits you going forward. If you are going to stick with the Nodemcu LUA firmware you can determine the version by typing:
print(node.info())
at the command line prompt.
There are alternatives to using ESPlorer e.g. Putty or Coolterm that will give you the raw output from the device with no interpretation. So if you have the correct serial port settings and the device plugged into the USB port it will show the banner when you reset giving an indication of the origin and version of the installed firmware.
In ESPlorer, there is an option under settings which if unchecked will stop looking checking for the version of the code.
For whatever reason, ESPlorer is not designed to read nodemcu version.
The error message throws you off, could lead you to think, there is an error.
At best, the above error can be ignored. It has no impact at all. In background, init.lua is up and running.
I have two computers; one MacBook Pro and one desktop PC running Windows. For various reasons I prefer writing code on the MacBook, while I keep the desktop PC mostly for gaming and entertainment purposes.
Since I've gotten so used to programming on an OSX keyboard layout, I often find it cumbersome to start working on something while I'm on my Windows computer. And since I'm ridiculously lazy I also find it cumbersome to get my laptop out of my bag so I can switch to using that instead. This usually results in me not bothering to do much work while I'm on my desktop (which depressingly enough is most of my evenings).
I guess I'm looking for a way to quickly enable an OSX keyboard layout in Windows. I'd also like to run Ubuntu in a VM on Windows, and use the OSX keyboard there as well.
Possible?
You can use Microsoft Keyboard Layout Creator to create a custom keyboard layout on Windows that mirrors the Mac OS one.
Ubuntu has an infinitely flexible and impossibly complicated keyboard layout system called XKB, which has limited documentation. Ubuntu probably already has all the data for the Mac keyboard layout you want stored among the hundreds of files in /usr/share/X11/xkb/, but figuring out how to load it will drive you crazy. You might have luck asking about this on Ask Ubuntu or the Unix stack exchange.
You could have a look at Synergy, using your Mac keyboard on both the PC and Mac.
I'm working with an 8051 (Cypress FX2LP) that doesn't have jtag/bdm capability. Typically, developers on this project have been using ad-hoc serial printfs for debugging. I'm looking into options for serial debug monitors such as Keil's Mon51, Isd51 or IAR's generic ROM-monitor.
I'll need to modify/configure this debug monitor to write to code RAM (to set software breakpoints). I'd guess that most 8051 debug monitors offer the ability for such modifications in order to support Harvard architecture or bank switching.
Does anybody have recommendations for serial debuggers for 8051 or similar processors?
Have you had to modify it to write to Harvard code RAM or flash etc?
I used for years Keil uVision PK51 and the Cypress FX2 EZ-USB Development kit. This kit (EZ-USB_devtools_version_261700.zip) worked correctly with FX2 and FX2LP.
It includes a Windows driver that automatically downloads the monitor firmware on board and stay resident in 8051 memory. This monitor takes control of one of the 2 serial board and manage the communication with the debugging tool. You have to set the Keil environment debugger to use the "Keil Monitor-51 driver".
Once your fw is downloaded and running you can set breakpoints, display watch, etc...
The Cypress driver works correctly with Windows 2K/XP. I never tried it with Vista or later. Probably there is a newer version of the Cypress that is able to run on the latest Windows.
Good luck
I have been using Mon51 with the Cypress FX2 for going on 10 years with very good success. In addition we use the RTXtiny task switcher and code banking. I have found the monitor to be generally solid and with enough functionality for our needs.
The Mon-51 code comes as a library from Keil, so it is not available. A couple of years ago I was having trouble getting code banking to work with the monitor, and since I wasn't getting very good support from Keil, I started to disassemble the monitor to figure out what was going wrong. Before I got very far I solved my problem and I never finished the reverse engineering project.
Our hardware platform is "von-neumanized" so that code and xdata space overlap. This is necessary for the monitor to work correctly. We have modified the monitor initialization code so that it runs at 115200 baud from an external uart and that works well. In addition we had to build our own version of the monitor so that it was located at a different location in memory. Keil has actually made it pretty easy to configure things without having to dive into the actual monitor code.
I already have experience with setting up virtual machines, running them and other minor tasks. Im a gamer, so I wont get rid of windows (for now at least...) but I do want to be a great programmer and to be involved with the Open-Source community.
Id like to know if its a good idea to do my programming in linux through a virtual machine, vs giving it a partitioned section of the HDD. Id like to know about performance pros and cons and functionality.
All responses are appreciated, thanks in advance.
The type of programming I intend to dive into :
Android Dev, Web Dev, Desktop Dev...More Android and Web right now though.
So im looking at C#,C,C++,Java,PHP,HTML,MySQL...Off the top of the dome.
I do web designing as well, so dreamweaver is added as an "essential". But im sure I can do dreamweaver files and upload them to the server after programming in Linux...Right?
And any info on IDE's in Linux for the above mentioned are appreciated, but i would prefer going the coding route and understanding the essence of whats happening "under the covers"
Thanks to all for reading, I appreciate it.
Hope this isnt confusing :S
There is an easier solution..
I still have to use Windows for Symbian programming so I use a Wubi and Ubuntu to provide my double bout into Linux..you deploy Wubi uses a large file and thus no need to worry or mess with creating a partition..
I have used it for 18 months with no data loss and no worries..
There is also another tool called andlinux:
http://www.andlinux.org/
It uses colinux to run Linux as a program inside windows..
A couple things:
If you're using an IDE, there's no point to coding on Linux. Linux is nice for programming because the command line tools are awesome. Netbeans and Eclipse both work fine on Windows. All you'd be missing is makefiles (which IDEs don't use anyway).
Using a virtual machine would be annoying (working with the window and stuff) and slow. Try AndLinux if you want to have Linux running in Windows. It sets up X and Pulseaudio for you, so all of your programs will appear to be native. It's basically a way to run Ubuntu as a Windows service (all Ubuntu packages for your architecture are installable).
If you just want the fun of Linux command line programs without access to all of Ubuntu, cygwin is smaller and might be faster.
If by "Dreamweaver files", you mean HTML/PHP/CSS, then yes, you can just upload them to the server. As far as I know, the only ASP or ASP.net compatible server is Microsoft's, but why use that anyway?
EDIT: SO didn't give me enough space in the comments to answer your question..
AndLinux and Cygwin are basically just better ways to do your "virtual machine" idea.
Cygwin adds a posix layer to Windows (basically everything you need to compile Unix/Linux/BSD programs). This means that you can generally take a Linux program and just compile it on Windows and have it work. They also have repositories, but in my experience, the cygwin installer is slow and hard to use.
AndLinux runs the Linux kernel as a Windows service, giving you a similar experience as running it in VirtualBox/other virtualization programs. However, it also sets up X (the graphics layer for Linux) and PulseAudio (a sound system that lets you run sound over a network), so that when you run Linux programs they act and sound like native programs. I also like AndLinux better because you have access to all of Ubuntu's programs, and apt-get is easier to use than cygwin's installer. Also, if you use AndLinux and later to decide to go 100% Linux, you're basically already using it that way.
What I'm getting at is: If you want to run Linux in a virtual machine, don't. Just install AndLinux. It will be faster and it's much easier to work with (since everything is just a normal window).
Here's an example of the difference:
Screenshot of AndLinux: The program in the bottom right corner is running in AndLinux. Notice how it just looks like a badly themed Windows program? Compare that to something like this, where you have another desktop in a Window.
And still.. there's no reason to virtualize Netbeans. It's a native Windows program and you can gain nothing and lose a lot of speed.
If you're interested in Android development and you want to use Linux, then I would recommend you do your development in Eclipse. Eclipse is available for Linux and if you get Ubuntu then Eclipse is amazingly easy to install. I used VirtualBox + Ubuntu + Eclipse for several projects I worked on. If you decide that Linux is not for you and your project was in Eclipse then you will have no problem switching back to Windows since Eclipse is available for both operating systems.
The ONLY problem I had was the screen size on the virtual machine... if you have a big screen and you use a virtual machine then you might get limited to a fraction of your actual screen resolution. It's very easy to install Linux on a second partition, so I would just recommend you go with a second partition if you want to fully utilize the size of your monitor.
My setup is sort of the opposite: I run Linux as my main OS, both at work an at home, and I have Windows in a virtual machine. On a modern computer with adequate memory the performance of development tools is not a problem. I work with Visual Studio in the virtual machine, and I have seen few performance issues. (But note that this is on a fast computer, and that you may need more memory than otherwise, since you are running two OS:es at the same time. On an old computer with less memory it can become unbearable.)
Dual-boot, where you have to restart the computer to switch OS, doesn't work well for me. It takes way too much time to switch, and really need to switch back and forth. Having Windows in a window works much better for me, and you can maximize that "Windows window", so it looks like you're just running Windows.
One thing you may want to look at is to have Linux running in a VM, then configuring Samba to allow the host to network-mount pieces of the Linux filesystem so that you can operate using Windows tools, and have Linux running the server processes (e.g., httpd). Alternatively, I'm sure that there are shell extensions for using FTP, NFS, or SSH/SFTP servers from within Explorer, but I've not looked at any for a long time.
If you should happen to need to use graphical Linux tools then you can use the X server found in cygwin for that.
The downside of this plan is that Samba can be a bit tricky to configure, but you get to use the Windows tools you're already familiar with.
I had no issues running Ubuntu via VMWare. You can easily switch to full screen mode anytime. Strongly recommended. One shortcoming is that Linux will not be exposed to the full potential of your hardware. Compbiz Fusion failed to work as a result.
Given that you're a gamer, I'm thinking your machine should be fast enough to run Linux in a VM. Best to try out the VM before messing with disk partitions.
I use physically separate machines to run Linux and Windows (and MacOS X). This means that I don't have to reboot to do something different, and each system gets the full power of the hardware.
Disadvantages: more desk space used, more time and money spent maintaining hardware (though if you do a rolling upgrade, this is mitigated - Linux runs most happily on not-quite-new machines). Doesn't work so well if you like carrying laptops around.
Be aware that VMs universally don't give you full graphics acceleration. This can be a non-issue (many programs must cope with Intel GMA anyway), or it can be a showstopper. Your choice.
