Fast SPI possible on PSoC4 ?
In my application, I need to transfer 64 bytes of data bidirectionally very quickly SPI. Ideally 8MHz or higher. However, when the SPI is running at that speed, it seems to be impossible to write and read data quickly enough to keep the SPI component busy. This results is a small gap between bytes, costing precious time. I have tried using the standard WriteTxData() and ReadRxData() functions.
How can I transfer bytes over SPI at the maximum possible rate?
