Byron Lathi	aca739338a	Remove spi_word and replace with spi_deselect ... Since the goal is to have the MAX3421E working, which uses multiple 8 bit transfers, we should support multiple 8 bit transfers instead of trying to use 16 bit transfers. When using spi_byte(), the device is automatically selected. After you have made as many transfers as you want, you must deselect the device with spi_deselect().	2022-03-10 14:43:49 -06:00

Byron Lathi	35973473d3	Change spi_write_byte to spi_byte ... the SPI module reads and writes at the same time. If you don't want to write a value, then write all zeros or whatever the device you are communicating with wants.	2022-03-10 12:14:07 -06:00
