Sorry I'm working on the Master and some quick calculations on a scrap of paper showed that a PIC was not man enough for the job so I have had to resort to a different processor :-( >I find the documentation somewhat poor from Microchip. There are >plenty examples of IIC and SPI master mode >but when it comes to SLAVE mode then the app. notes lack. There is code for Slave Mode in the book but I have not taken a look at it so I cannot comment on its usefulness. That is for a future date, when I have the time or need.
