I've got alot of these thermalcouple chips and ive got plenty of thermalcouples. I would like to interface them with a 18f4550, i have never used a SPI device or I2C, the link above is a sample pic circuit that uses my particular temprature chip. but uses another PIC. Im assuming you just use some serial in code but i dont understand the electrical connections, the pin names dont match? is there a chart somewhere that has put pin a to slot b? I assumed SDO -> SDO and such. if anyone has an article on using the SPI funtion with schematic and reasons for what pin goes to what i would be grateful.
