ESP32DMASPI SPI library for ESP32 which use DMA buffer to send/receive transactions [!CAUTION] Breaking API changes from v0. The device uses SPI for control and raises interrupts on GPIO pins for feedback. Note SPI1 is not a GP-SPI. However, the total Sample rate is lower Hideakitai has another library esp32-slave-spi which doesn't use DMA and simpler (and slower but that doesn't matter much giving that you had a slower Arduino as SPI master). I wonder where I can find SPI sample code for ESP32C3. SPI Multiple Buses /* The ESP32 has four SPi buses, however as of right now only two of * them are available to use, HSPI and VSPI.
