Sorry for creating this issue, the problem was on my client side. My variable didn't have the right type and I was limited to signed int.
I changed my code from:
int16_t image_size = stoil(argv[5]);
To:
uint32_t image_size = stoul(argv[5]);
Pitou!
Glad you got it sorted. :)
Hello,
I've setup a PI4 along with 2x 128x64 panel. Everything works fine with the included tools, but I can't send images of more than 32767 in size. The server doesn't even react.
Here is an example of a 32767 frame:
pi@raspberrypi:~/led-matrix-zmq-server/bin $ sudo ./led-matrix-zmq-server --led-cols=128 --led-rows=64 --led-chain=2 --led-slowdown-gpio=3 Listening on tcp://*:42024 @ 24BPP Frame dimensions: 256x64 Expected frame size: 49152 bytes Frame size mismatch! Expected 49152 but got 32767
And a 32768 frame:
pi@raspberrypi:~/led-matrix-zmq-server/bin $ sudo ./led-matrix-zmq-server --led-cols=128 --led-rows=64 --led-chain=2 --led-slowdown-gpio=3 Listening on tcp://*:42024 @ 24BPP Frame dimensions: 256x64 Expected frame size: 49152 bytes
As you can see no error message. I can do some tcpdump/wireshark if needed.
I also tried to change the type to unsigned int here:
unsigned int frame_size = zmq_sock.recv(&frame, expected_frame_size);
But it didn't help.
Any idea?
Thanks!
