No but I followed up the logic in the code above: // Which RC pin of the SPI port should be used for the first module // allowed values: 0 or 1 for SPI0 (J16:RC1, J16:RC2), 0 for SPI1 (J8/9:RC), 0 or 1 for SPI2 (J19:RC1, J19:RC2) #ifndef AINSER_SPI_RC_PIN_MODULE1 #define AINSER_SPI_RC_PIN_MODULE1 0 #endif // Which RC pin of the SPI port should be used for the second module // allowed values: 0 or 1 for SPI0 (J16:RC1, J16:RC2), 0 for SPI1 (J8/9:RC), 0 or 1 for SPI2 (J19:RC1, J19:RC2) #ifndef
