Can I use this library with a 32x64 panel using Python ? #2

I'm not sure if I should explore this library as I have been using @hzeller rpi-rgb-led-marix library using the python bindings --thx. Overall I am still looking for the right way to use the Raspberry Pi 5's that I have purchased.

bitslip6 commented 3 weeks ago

Don't have Python bindings as of yet. Maybe in a couple of weeks. I still need to add GPIO support for PI4 and PI3 / Pi Zero.

ElBertrando commented 3 weeks ago

Understood --- I will keep an eye out for them -- thx

how many address lines does your display have and what "hat" interface are you using ? I currently support adafruit hat and the electrodragon hat. Python wrappers should be available next week.

Ive got the 64x32 RGB LED Matrix, and I am using the "Adafruit RGB Matrix HAT + RTC for Raspberry Pi" ---

The electro dragon hat is significantly better as it allows running 3 panels in parallel. It's also only 15% of the cost. https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-raspberry-pi/

I have GPIO mappings for the adafruit hat, but it is a compile time option, see the readme for details.

Unfortunately I've already purchased 10 pi5's and 10 hats for a continuing project. I only am using one panel per project. Having said that, will I be replacing the hzeller/rpi-rgb-led-matrix library with this one or will I install both of them to run side by side ? In the future I will be checking out the electrodragon once I get this working, and probably make the switch.

But, you CAN wire as regular without any hat, try it

might have problems with the voltage level shifting as the GPIO is 3.3 volts and the hub75 panels are 5 volt. the adapter boards provide level shifters (logic bus) but some panels might work directly connected. the pin out is in include/rpihub75.h there are 2 address mapping #defines, 1 for hzeller boards and the other for the adafruit board. the readme has instructions for compiling with either.

You don't need the Hzeller library just this one. What's your target language C, C++, Python, something else?

ElBertrando commented 2 weeks ago

I have a working Sign that I wrote using Python bindings with Hzeller library using Pi 4
