Hi all,
Yet more questions I'm afraid! I'm trying to design a circuit at the moment, I would like to use ic's and modules attached to one pic that use I2C and SPI.
I will have 3 I2C chips and a SPI radio module running, I think I probably know the answer but its best to ask first I feel! Most pic's have the I2C and spi in one module, I would like to use the smallest pic I can, (8pin) but am gussing pull ups for I2C would mess up SPI coms?
The good news is I still have 4 io left if I use the I2C module. Has any bit bashed SPI or I2C? which might be easier? As I want to use 3 I2C devices I guess I will want to write a routine for the SPI (1 device) anyone know of any pitfalls or problems I might encounter?
Cheers Geoff
