I have trying to active a 16x32 led matrix panel with my raspberry pi but It has not been possible. I have been following the information of learn.adafruit.com but I
don’t know if it’s missing information or It's out of date.
I did the connections like they are shown here:
https://learn.adafruit.com/connecting-a ... he-display
I downloaded the software from here:
https://github.com/hzeller/rpi-rgb-led-matrix/
On file lib/Makefile, I search the line "DEFINES+=-DRGB_CLASSIC_PINOUT" to enable it but It does not exist, so I added It to the code.
I ran the command "sudo ./demo -D 1 runtext.ppm" to test the programm and at first I got the error "snd_bcm2835 found that the pi sound module is loaded". I could fix
this error putting in off the line "dtparam=audio=on" on the file "config.txt".
The error is not displayed any more and the test command seems like It's running succesfuly but only a few leds are turning on into the panel.
I want to know if the connections with Raspberry pi or the software have changed for the led matrix panel can work.

Re: Led panel 16x32 does not work with Raspberry Pi
Which model of Raspberry Pi are you using?
Can you post some photos of the wiring between the Pi and the LED panel connections? 800x600 works best.
The RGB Matrix Bonnet is out of stock, but something you might want to get notified for when it becomes available again.

This does not look like one of Adafruit's 16x32 RGB LED Matrix panels. Where did you purchase it?

I Purchased the led matrix in the local market (Vistronica). It was my understanding that all led matrix panels are the same.
