Jatson nano B01 - how to connect max7219(dot matrix) using SPI & python?

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 :<
