FT900 documentation

[dreiber]

I ws looking at the help information for the MatrixRGB click board. I wanted to find out more information regarding the initialization parameter. The help documentation indicates there is "more info inside firmware documentation". For the onboard FT900, I assume. Where can I see that documentation?

Hello,

Here you can find the source code of the libraries:
https://github.com/MikroElektronika/Matrix_RGB_click

Also, there is the "Learn page" for this click with the explained functions and how to use it:

Kind regards,

Thanks Jovana.

I have a 32x32 RGB LED Matrix Panel that I bought a few years ago. The signal connector pinout on the back (HUB75) appears to be identical to the connector on the Matrix RGB click board. I am using a Fusion v8 board running v 6.2 of MikroC for ARM and a STM32F407ZG CPU. I get nothing on the matrix when I compile and run the program.

I tested the matrix and cable on a Rasp Pi and they work, so I am wonder where to look next. I used the default 32x32 pattern _MATRIXRGB_PATTERN_1_MAP_5MM in the program.

Hello,

Check if you set the configuration bits correctly.
Do you have the panel with 6mm grid or 5mm?
In the attachment, you can find an example. Run it and let me know the result.
If you have the panel with 6mm, in the code you need to write _MATRIXRGB_PATTERN_1_MAP_6MM instead of _MATRIXRGB_PATTERN_1_MAP_5MM.

Kind regards,
Jovana

Thanks Jovana. The attached project doesn't work either. The panel I have has a led spacing of 4mm. Maybe that is the problem. I'll check my configuration.

Hi,

The library is written for 5mm and 6mm panel, so maybe this is a problem.
In the attachment, you can find one more project so please try it.
Don't forget to supply the panel with 5V.
Can you send me a picture of your connection?

Kind regards,
Jovana
