HELP with 16x32 3 chain panels

1

Hello All,
I have a Pi4 with Adafruit-hat-pwm installed. I’m running (3) chained adafruit 16x32 LED panels. I downloaded the GitHub files and have tried to make them and run the demo but I am getting the following errors when performing the “Make” command in the main folder.

make[1]: Entering directory ‘/home/pi/rpi-rgb-led-matrix-master/lib’
g++ -I…/include -W -Wall -Wextra -Wno-unused-parameter -O3 -g -fPIC -DDEFAULT_HARDWARE=’“adafruit-hat-pwm”’ -fno-exceptions -std=c++11 -c -o led-matrix-c.o led-matrix-c.cc

I am NOT a programmer, only a hobbyist trying to build a METAR Ticker using this panel. I had this working back in 2016 and something happened to my memory card so I am starting over but noticed that some of the HZeller files have been updated recently and thinking maybe this is my issue?

Any help is greatly appreciated.

I have an older version of this rpi-rgb-led-matrix respository and I am able to get the examples-api-use demos to work, however, I cannot get the Python examples to display on the LED Matrix. It shows in terminal that the program is running, however it does not output to the LED matrix.

Any idea what would cause that? When one set of samples work, but the python samples do not.

Thank you!

You are running MAKE from ~/rpi-rgb-led-matrix ?

Perhaps share the code to help answer? Are you sure it isn’t a hw issue?

if you look in the original post, I shared the errors that I get when running the Make from rpi-rgb-led-matrix from the current github repository. I downloaded the repository and I believe I have run the Make file in each folder that there is.

Hi, I did an identic thing 2 weeks ago. I used initially the script provided on the adfruit website. You find it with the bonnet/hat product including step-by step instructions. In 2 mins you have a running system by answering 5 or so questions. Start with a blank new system. Greetings Dieter

just to be clear, you are building the unmodified git tree that is up to date with master?
If you are not sure, can you do a fresh git clone?
and I’m assuming you are building this on the Pi4 with an up to date linux distribution on it (it has to be recent anyway since Pi4 is recent)

I’m using an Rpi 3B+ I believe. I have an Rpi 4 also that I intended to replace it with. I originally had this project running in 2016 but something happened to my memory card so I’m having to build it back from scratch. Talking with the guy who wrote the program I’m using, he mentioned that the rgb library has changed and might need to be modified for the way the code is written?? As I said I’m not a programmer, and have very little understanding of coding. I don’t know what you meant by downloading a gitclone.
Thank you for any help you can provide!!
