TLC6983: Control through STM32

Severin Getzner

Hello,

I would like to create a LED matrix for a product. The specifications are

  • a 16 x 16 matrix
  • that is monochromatic
  • but with the corners of the matrix cut off to fit on a round PCB
  • controlled by a STM32 MCU

I read that the CCSI interface is very similar to SPI, but has an "always on" clock. Is it impossible to control it via SPI or do I have to write my own driver? Also, is a circular matrix possible and how do I realize the monochromatic matrix? Just connect the white LEDs to either R, G or B?

Thank you very much.

PS: I thought of the SAI (Serial Audio Interface) as an alternative. It could go up to 49.152MHz on the clock line.

    Hi ,

    Currently we have a new device called TLC5899 which is the bridge IC converting Standard SPI to CCSI. customer can add one bridge IC between MCU and LED Drivers, then can use SPI to control the LED Driver. the bridge IC is small and has competitive cost. if you need more information, please contact with FAE and Marketing since the device is not public on the official website yet.
