Can I get some hints on tackling DI and DO simultaneuosly?The basics of interfacing SPI devices should do.
Asok, Its been mentioned many times here in the past, SPI is VERY easy to implement. Don't be worried about doing DI and DO "simulataneously" They happen as the device is clocked, so you can clock out DO and then read DI on the same clock cycle. Stuff the received bit into the carry flag and then rotate it into a byte. It takes more logic to do that for 24 bits or whatever (3 bytes), but not much. Steve |
