Led panel P5-6432-3528-16S-B4 with ICN2038s chip

[maksun]

Hello,

I just would like to know if someone here managed to make this panel working? I'm using the active board from electrodragon, I'm trying to help a friend so I did some research and read the following:

"Check the controller chip that install the LED panel, if are ICN2038S or FM6126, those are not compatible Smartmatrix because these chips require three clock pulses by Latch."

I will tell my friend to try the led panel type FM6126 in case of... Any advice is welcome ;)

Thank you.

Hello,

Looks like this chipset is similar to the FM6126A as I managed to make it working with the "--led-panel-type=FM6126A" parameter. FYI, it was an ABCD panel style.

Hello I am able to display something on matrix (ICN2038S). but refresh is bad. If anyone is interested I can post more here

I have a P2 panel with this same chip. While I can display something on the panel, the addressing isn't right I would be interested in knowing more about what you've been able to do.

most P2's have different row driver (320x160mm has 1/40 scan). This requires handling the row driver in addition to ICN2038s. please check your matrix. If your matrix is 256x128mm then you only need the ICN2038s driver (scan will be 1/32 which is OK.)

Yes, physical size is 256x128, with 128x64 pixels and 1/32 scan.

here is the code

define BITS_ON MTX_RGB_PINS

define BITS_OFF 0

define ICN1038S_REG_1 11

define ICN1038S_REG_2 12

define ICN1038S_DEF_REG1 (0xf000) // register 1. (11)

define ICN1038S_DEF_REG2 (0xf000) // register 2. (12)

void matrix_write(uint16_t uVal, int width, int reg) { uint16_t value;

MTX_LAT_LOW();
MTX_CLK_LOW();
for (int i = 0; i < width; ++i) {
    value = (uVal & (0x8000 >> (i%16))) ? BITS_ON : BITS_OFF;
    if (i > (width - reg)) {
        MTX_LAT_HIGH();
    }
    PIN_LOW(MTX_RGB_PORT, BITS_ON);
    PIN_HIGH(MTX_RGB_PORT, value);
    MTX_CLK_LOW();
    MTX_CLK_LOW();
    MTX_CLK_LOW();
    MTX_CLK_HIGH();
    MTX_CLK_HIGH();
    MTX_CLK_HIGH();
}
MTX_CLK_LOW();
MTX_CLK_LOW();
MTX_LAT_LOW();

} void icn1038s_init() { matrix_write(ICN1038S_DEF_REG1, LED_WIDTH, ICN1038S_REG_1); matrix_write(ICN1038S_DEF_REG2, LED_WIDTH, ICN1038S_REG_2); } I repeated the clock/latch signals because my MCU is fast.

@alsaleem00 looks like the right solution for the ICN2038S. I am trying to get a 128x128 panel to work with this chip (https://github.com/hzeller/rpi-rgb-led-matrix/issues/1713).

Your code does not look like it is written for hzellers library. If you could give more (code) context that would be helpful.

[alsaleem00]

This code was written for STM32F722. The PIN_/MTXCLK/MTXLAT/MTX_CLK_to control the pin directly.

Hi Alsaleem00, Thanks for your reply.
