How I can clear SPIslave MOSI buffer?
Hi.I want to communicate as SPI with multiple devices such as 2 ~ 4. But when the SS pin states HIGH, I need to do not receive the data from master but it retuned 1(spi.receve() == 1). So I think when MOSI buffer have some datas, It need to clear the buffer of MOSI.
