Assume you have an MCU running at 80Mhz (Currently working with TI M4)
This MCU has 128kB of memory allocating some data.
What would be the proper way to transmit this data in its raw form (bits only, no start bits, no end bits, no handshake, no acks, no gaps, no protocol) over one of the MCUs pins and a clock on another pin.
I need to reach 20Mhz, minimum 15Mhz. I was thinking of using an FPGA but an MCU would be much easier (and cost effective).
SPI can work at 1/4 the MCU speed so, technically, it is possible to run SPI on Tiva in 20Mhz. but I do not need the SPI protocol...
