I've read the datasheet of both PICs on the (M)SSP peripheral in I2C mode but couldn't find out how to interface the bus. I2C or inter-integrated circuit is a widely used serial communication protocol in the electronics world. No device ever holds a bus line up — it can only bring it down. The circuit for receiving SMS using a GSM moden is very simple, you just need 3 male to female header pins. Other PIC18F variants have the ECCP module found on the PIC16F device family. Interrupt is “requesting" the processor to stop to perform the current program and to “make time” to execute a special code. The first and foremost thing is the embedded software that decides functioning of the embedded system. The code to do this looks rather long, but it is not complex. The important topic titled MPLAB ICD 3 In-Circuit Debugger is explained in detail with code examples. The R/2nR DAC circuit, otherwise known as the binary-weighted-input DAC, is a variation on the inverting summing op-amp circuit.
