Hi everyone.
A project I have began working on centers around using a HUB75 matrix panel.
For the controller, I am using a Huidu HD-WF2 controller board which I have updated the firmware to ESPHome.
The matrix panel I have chosen for my first attempt at doing something like this has turned out to be rather challenging to set up. I have gotten a P5 outdoor 64x32 1/8 scan, which is not playing nice with ESPHome.
The matrix panel works when using the original Huidu firmware and programming with their software, HDShow or HD2020. Through the configuration settings I would choose the HD-WF2 board, and then select the P5 outdoor matrix with 64x32 1/8 and all was good.
With ESPHome, I have tried quite a few different settings based on hours of searching for info. This panel is stated as being 1/8 scan and is causing me grief. For example using the following config setting, of which from searching were suggestions to try actually make the matrix a jumbled mess, so they do not help at all:
scan_wiring: SCAN_1_8_32PX_HIGH
and
scan_wiring: FOUR_SCAN_32PX_HIGH
Does anyone have any suggestions or have experience with the P5 outdoor 64x32 matrix panels? Unfortunately there is no manufacturer info on the back so I can’t search for specs with that info.
yaml I simplified, based on the example from a git repository in the comment section (I removed the “custom-component” in order to use ESPHome’s integrated hub75 component). It should draw a red box around the perimeter of the panel and print one line of “Hello world!” at coordinate (2,2):
# led-matrix-hub75-huidu-wf2.yaml -- ESPhome config for the HUIDU HD-WF2 LED matrix controller
