Hello everybody,
we are trying to implement a new light with a LED1642 driver and are confused about its SPI interface. According to the startup guide a data transfer like this:
Legend: Red->CLK, Green->LE, Blue->SPI DATA
should, in accordence to our Layout, let all the white LED light up, but it does not. There is no reaction at all. Due to an "error" in my Programming (we are testing with a STM32f207 nucleo board) a pattern that looks like this:
Legend: Red->CLK, Green->LE, Blue->SPI DATA
where some of the LE Signals are shifted, Lights the LED`s I want but I cant really reproduce it and its also not in accordence with the startup guide. Has annyone an Idea what could be Wrong with my timing?
