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...

Not only is GPIO36 an input-only pin, it also does NOT feature pull-up/down resistors: Note 2 The following pins are input-only. These pins do not feature an output driver or internal pull-up/pull-down circuitry: SENSOR_VP (GPIO36), SENSOR_CAPP (GPIO37), SENSOR_CAPN (GPIO38), SENSOR_VN (GPIO39), VDE...

I am running a fork of the official firmware by loboris. The firmware has FTP server and Telnet server. If you set them up in main.py you can get remote access through Telnet (same as REPL) and upload files with FTP, simultaneously.

No. Have the module with the logging function run import os This forum is to support MicroPython: users assume a knowledge of Python. Your queries are elementary ones about the Python language. I would advise you to learn the language using Python on a PC with a book or online course. That was the ...

...Since you don’t have great control over when a module runs (at first import), it typically shouldn’t do anything else than define functions and classes, and possibly initialize some things. Any code that needs to run at a determined time should be inside those functions and classes. I got it now...

Python uses Duck Typing . It is normal to do things like: import machine i2c = machine.I2C(1) import my_module my_module.run(i2c) my_module only needs to import machine if "machine" appears in its sourcecode. The module can feely call I2C methods against the passed I2C instance: Python determines t...

I am mainly using MP on ESP32 with Loboris port so I do all my editing via a FTP server. I setup in filezilla that it will open *.py with my selected IDE (note++ ha ha) then I just edit it and click save and filezilla will auto update it over FTP then I just swap to my puTTY terminal window(either ...
