Add a new panel - 80x40, 10s, outdoor, ic - FM6124

[xuniuer]

Hi @board707

I have a new outdoor panel with the resolution of 80 x 40 and 1/10 scan. The panel IC is FM6124.

I use the pattern test program (based on RP2040 pico) with the following parameters to init dmd.

#define RGB80x40_s10_pt1 4,80,40,10,1
typedef DMD_RGB<RGB80x40_s10_pt1, COLOR_4BITS> DMD_RGB_80_40_10s_4bits;
DMD_RGB_80_40_10s_4bits dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

uint16_t bg = 0;  // background - black
uint16_t fg = 0;  // foreground

void setup(void)
{
    dmd.init();
    fg = dmd.Color888(0, 0, 255);
    dmd.setBrightness(10);
}

void loop(void) {
    // fill the matrix with points row by row
    for (int i = 0; i < dmd.height(); i++) {
        for (int j = 0; j < dmd.width(); j++) {
            dmd.drawPixel(j,i, fg);
            delay(30);
        }
    }
    // clear the screen
    dmd.fillScreen(bg);
}

I've got the following the result:

I dont' see the leds are not ON row by row, then how to config the parameter 4,80,40,10,1 to support the panel, please advise.

Thanks

Hi It seems that your panel has one of the known pattern. Try use this:

   4,80,40,10,102,1,PATTERN_UPS

I have a try using your advise, the config makes the lower rows of upper half panel ON row by row firstly. I change to use 4,80,40,10,102,1,PATTERN_LPS, it works.

Thank you.

Sorry, I was unable to distinguish between LPS and UPS patterns in the video.

Yes, it's difficult to tell the difference from video. Take it easy.

Thanks to the library and its great arch, it's very quick and easy to support a new panel. Thank you very much.
