I'm prying to program an esp32 with micropython but when I go to flash micropython to the board the port for the esp32 won't come up.
I have made sue that my system can can connect to the esp32 and it can shwon in the
screenshoot
I have also tried to install/update the CP210x driver but nothing will work for me
if you can help me out that would be great and thank you in advance.

I just bought an ESP32-S, which looks like this : https://99tech.com.au/product/esp32-s-ai/, except the one I bought only have the writing "ESP32-S" and the espressif symbol instead of AI thinker symbol.
I have been searching the internet for a week for a specific tutorial for this "board" and found nothing.
what I have found is mostly that there is ESP32, ESP32-S2, ESP32 WROOM, ESP32 WROVER... but which one is my esp32-S? is it the same with esp32 or is it the esp32 wroom or something else? if I am going to program this using platformio, which board should I pick? or does it matter which board?
thank you in advance
Try the "Espressif ESP32 Dev Module" it works for me with the Arduino framework. My chip has ESP32-WROOM-32D but it says ESP32-S on the back of the board.
It appears to be compatible with the ESP32 WROOM module.
I am using SAMA5D27-SOM1-EK1 embedded board.
I build for it Linux distribution using Yocto project following the steps described here :
Yocto_Linux_Kernel
I can connect my board with the Ethernet port and it's working. But I want to connect to network using WIFI instead of Ethernet.
I don't find how to do that. Help me please! Thank you!
I would like to know if there is a way to connect an esp32 cam via an esp32 to the pc to program it.
I have only found tutorials to connect it via an arduino or FTDI...
ESP32-CAM doesn't have USB->serial converter so the only way to program ESP32 for the first time is via serial. After uploading sketch via USB-TTL converter you can use OTA to update ESP32 via Wi-Fi but if you don't have FTDI converter it's useless.
Another solution is to use arduino board as USB-TTL converter because converter is already included on most of the arduino boards (nano, UNO..).
Yes, you can connect it to a PC - but, as you said, only using an Arduino or FTDI.
You can't connect it directly.
The ESP32-CAM doesn't support USB for communications. FTDI allows the PC's USB connection to communicate with the ESP32-CAM's serial port. They can't communicate without some kind of adapter - that's what FTDI or an Arduino are for.
Bought a Makerfab SIM808 ATMEGA328 module from Robotshop and I connect the micro usb to the module. The port does not show up on the ports list on the Arduino IDE and the documentation is very poor. Does anyone have any experience with this and know what I am missing.
Hardware details can be found here.
This is the datasheet.
Any help would be appreciated here.
do you install the CP2104 driver to your PC before use it? This board use the CP2104 at the USB to TTL. Here is the driver:https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
Please try it. Hope it help for you.
I am new guy on Arduino and johnny-five. I am not clear about the way johnny-five work. JS code will run on computer or run directly on Arduino board? Besides, can we use johnny-five for IoT? because I have not found any component to support Arduino uno connect to internet(call rest api or Azure service,..)
Thanks,
johnny-five uses Firmata. The Javascript code is running on your PC, and the Arduino is basically used as a peripheral — the Firmata firmware allows software on your PC to interact with all of the Arduino's inputs and outputs, but there isn't any real "intelligence" running on the Arduino.
Yes, it's possible to use REST APIs on an Arduino without the help of an attached computer, if the Arduino has an Ethernet Shield or some other method of connecting to the internet, but do keep in mind that the Uno only has 2kB of RAM and 32kB of ROM, so there's a limit to how complex you can make things.
You can connect arduino to a raspberry, it is not expensive.
