RGB 32x32 LED's aren't displaying anything with Bonnet #1243

I'm really sorry if this comes off very simple. I've recently installed and followed the tutorial for this using the adafruit installation, however, everytime I run the program nothing is displayed on the LED's. I've attached images on this post. I am using a raspberry pi 3b, 5V 4A DC power supply, 32x32 RGB LEDs and an RGB Bonnet. I've also attached an image of the first stages of the installation as the values are different from what is stated in the tutorial. Furthermore, I'm a beginner when it comes to raspberry pi any help would be appreciated. PXL_20210131_152027300 MP (1) PXL_20210201_161807945 MP PXL_20210201_161814049 PXL_20210201_161828011

If you use the Adafruit fork of this repository, please talk to them, I don't know what they're doing in their install script.

(Also, I suggest to not use a UI on the Raspberry Pi, but rather connect to it via ssh.)

Adafruit fork

Hi,

I use this tutorial I believe it's the same as the one stated here. https://learn.adafruit.com/adafruit-rgb-matrix-plus-real-time-clock-hat-for-raspberry-pi/driving-matrices

In the screenshot it shows that you're using the Adafruit installer script. This project has nothing to do with Adafruit, they are just using it. So if you have trouble with an Adafruit product, you should ask them.

If you want to use this project, make sure to read https://github.com/hzeller/rpi-rgb-led-matrix

For instance in your second screenshot, it shows that you're using the hardware mapping used in this project ('regular'), while if you use an Adafruit hat, you need to pass the command line option --led-gpio-mapping=adafruit-hat

Hi, I've reinstalled everything I've now got the code running, but everytime it loads nothing appears on LED board.

hzeller commented 3 years ago

what options do you supply ?

milajo2 commented 3 years ago

The commands I place are cd rpi-rgb-led-matrix cd example-api-use sudo ./demo -D0 runtext.ppm I've tried it with regular wiring using the updated instructions and my bonnet --led-gpio-mapping=adafruit-hat

I can get my LEDs working using my Arduino is there a possibility that I could run my Arduino using my raspberry pi and also add a touchboard sensor on my raspberry pi and get the two collaborating with one another?

Greetings,

So, you have the adafruit interfacing board? What model. TRY wiring the "regular" pinout, and try again... may be, adafruit board is broke

Best regards
