Brad Campbell af27d2d252 [CC2538-SPI] Implement SPI_FLUSH, spi mode, !CS ... Because the CC2538 has a multi-byte SPI RX FIFO, flushing the buffer requires more than just a single read. This adds a loop that empties the entire RX buffer on a FLUSH(). Different SPI chips needs different SPI settings. This commit adds a function that allows chip drivers to configure the SPI peripheral before using it. The frame pin the driver was using as a chip select does not work as most devices expect it to. It toggles after every byte, and most chips interpret that as end of message. To make drivers more reliable, each chip driver should setup a GPIO and assert it as needed.		2014-04-15 14:07:10 -04:00
