Hi guys, I'm using the Montavista kernel for 2.6.18_pro500, but this is more of a generic SPI question.
I'm trying to write a peripheral driver which uses the SPI. I have set up the SPI bus on SPI1, and I can initiate transfers over the wires (Logic analyser shows me line states) However, the device I'm talking to works in 16bit transactions where the first 8 bits are the address/register to read The following 8bits will clock the value of the register back to the master i.e.: to read the value 0x02 from register 0x03 the following transaction would occur MOSI: 0x03## MISO 0x##02 where ## are "don't cares" I can't seem to get this to happen using spi_write / spi_read. Does anyone know where some good pointers on using SPI are, or good examples are ?
