Ultimately, what I want to do is use Jatson to turn on or off all the LEDs that exist on max7219 when I want to.
I’ve done a lot of googling to do this, but there’s nothing I can do but set up spi1 pins using jetson-io.py.
Is there a way to send 16bit information to the max7219 module with python?
The first thing I tried was using ‘luma.LED_matrix’ open source (for raspberry pi) and, of course, random LED patterns were detected.
I don’t have to float the letters, I just have to all the LEDs on OR off, but I don’t know how to do this.
I know I must use SPI communication and I need to know the serial speed to implement it.
Honestly, I don’t know I understand it well.
What should I do about this?
What I want to do is simple, but it’s so frustrating to implement it that so sad :<
