Trying to create a fiber-optic transmission system between two LCDK's. We have built the simple transmitter and receiver circuits, and we are able to send and receive data. We are using GPIO8-12 as our output and GPIO8-10 as our input.
But our data rate is really slow. We are limited to a clock period of 1 ms, and are looking for a way to speed that up. Are there other clocks we can use to get a faster sampling rate? The AIC3106 sample rate of 48 KHz is a big improvement, but we are looking for even faster polling of the GPIO pins. Can we do that?
