Texas Instruments CCSI Frame

[Stomper]

Hello,

for an LED Matrix I need to talk to an TLC6983 Chip with an CCSI Frame format.
This means "Continuous Clock Serial Interface".

Looks like this:

Clock needs to be present all the time as the matrix chip has no clock internally but uses the input clock signal from the host device to scann lines.

I thought the LCD_RGB_PANEL Driver from the IDF could work to do this, but I cannot get this to run because SOC_LCD_RGB_SUPPORTED is not set and so the needed structures are not available.

Using a ESP32-WROOM Module.

What am I doing wrong or what interface should I use to reproduce the needed frame?

Thanks and best regards

The ESP32 does not have the LCD interface (from all the chips that are released at this point in time, only the ESP32S3 has that)

You could try the I2S interface, that has a parallel mode that may be useful.
