Hi,
There are lot's of cheep and good 16 channel LED drivers out there, Like MBI parts like MBI5043,MBI5045,MBI5030 etc... or from ST something like STP1612PW05 or similar ones. all of them seems to have a industry standard footprint and the protocol seems the same, I have bring them up by bit banging to them and they worked as expected, the weird thing is the LE signal which has this Number of CLK
rising edge when LE is asserted do different things! I wonder how to connect them to a normal SPI and could get the 30MHz SPI clock, do we have a trick? in this way we can achieve the maximum speed, also I prefer to use STM32 for these ones, so do we have something there to help?
