I’m using the hifive1 for a little personal project, connecting it to an ADC (MCP3202) via SPI1. I have a couple questions about interfacing with the ADC.
- Regarding IOF, does enabling the IOF let the hardware control the configuration of the hardware pins so “manual” GPIO configuration is not required, similar to the UART?
- Can the FE310-G receive a message from the ADC when it expects us to write three bits and receive 13? If so, what is the best way to accomplish this with the SPI1?
