I have once worked on MAX7219 and designed a scrolling text on LED Matrix 8x8, although I have used Arduino Nano for this project. Try this code out:

Code: Select all

import max7219.led as led

device = led.matrix()
device.show_message("Hello world!")

I have searched online and seems like there's no such library designed yet. You should design its library as you have already worked on the board. I have once worked on audio signals but I have used a TDA2030 audio amplifier. If you don't want to go through the software library trouble.

Yeah, littlefs works better than FAT in the file system. I have worked on it in the Raspberry Pi 4 Project.

Hmm yes. Maybe I could do it. Not sure.

Yeah it won't be that difficult, capacitive touch sensor is a simple analog sensor, so you should try creating its library. I have found this capacitive touch sensor library for Proteus, I hope it will help in your project.

Wow, you found a bug in MicroPython, that's kind of awesome in a way.

Btw I once encountered a similar issue while working on Arduino UNO and RPi0, go through a lot of trouble in solving it.

I used the API from blockchain.info for getting Bitcoin price data. From a quick glance at their site, it looks like they also offer Ethereum and BCH data.

There must be some data limit on it as on all Blockchain Technology related stuff, how many queries you can make per month for free?

RC522 is an SPI module, so you can easily interface it with SPI pins of ESP32. You need to download its third-party library and you will find ready to run examples to test it out. Try those examples and share your results.

Try this one out: mypackage ├── __init__.py ├── one.py # contains "import two" └── two ├── __init__.py ├── two.py # contains "import three" └── three ├── __init__.py └── three.py And then, you can access the package with: import mypackage.one import mypackage.one.two import mypackage.one.two.three Y...
