I want test Smartmatrix with APA102, I have open the library, but do not know where connect clock and data.
This library is for Kinetis/Teensy or its only for STM32 ??
I do not know what is photon, seem some board with STM32. I prefer develop my own board, but Im not sure if may be with Kinetis MK66 or only with STM32, and where connect clock and data.
