Thanks Roberth! So my guess was right and the logic was meant for a dev board to start when its console serial port is opened by a typical terminal emulator.

I have some thought about the two transistor/resistor reset circuitry. I grabbed the reset sequence with a logic analyzer. If esptool.py can control DTR and RTS individually, as shown on the logic analyzer and expected from pyserial module, then why not directly connecting DTR and RTS to GPIO0 and R...

The MicroPython implementation is uasyncio and it works well on ESP32. There is information about it here including a tutorial. tl;dr It can be installed using upip . Thanks pythoncoder, as always. I've not used MP for a while. I would humbly ask for a pointer to use upip.py. Do I just place it in ...

I'm considering porting the azure python sdk (preview) to ESP32 but the first thing I saw in the code was this asyncio module that supports concurrency. Is this currently supported in MicroPython for ESP32? How well is it support, if I may ask? Thanks.

Thanks. I need to investigate it a bit more. Used ESP32 for a while with MicroPython, which is great, but never tried doing SPI with it, fearing it would be too slow. I'll post what I find on this subject.

I use a version of avrdude to upload .hex files to arduino via SPI ins on raspberry pi 0w. I wish to move to ESP32 due to the lack of supplies of raspberry pi 0w. I wonder if anyone has done this already, on ESP32 in MicroPython, uploading intel .hex files to arduino via spi. Thanks. I'm fairly comf...

Hi, I agree with you that the ADC should be documented. The name analog-to-digital-converter really means nothing to those not knowing what it does. I'd rather call it voltage input. The 0-4095 to 0-3.3V mapping should probably be mentioned in the doc. The 3.3V supply may not be exactly 3.3V. If you...

Thanks! I was able to understand the code, which uses uart_set_pin() to set pins. I couldn't find uart_set_pin() in the repo. Could you help? Anyway, it doesn't seem to handle past pins, such as setting them to I or T with pull-down. I guess I'll have to do that myself right before switching the pin...

I am thinking about this scenario where I need more than 2 serial ports, (not gonna touch the one running REPL). I've done this on a dev board, activate a serial port with machine.UART() one a pair of pins. Then activate the port on another two pins. It works. However, I'm trying to do it safely. Wh...

I usually implement an end-of-message character and send my numbers by plain ASCII string. This way I can more easily decode the message. Another thing you can try is to use json format (still send it in with an end-of-message character such as \n). On PC side, use json module to serialize your data...
