Basic information
*Microcontrollers
*Differences compared to
microprocessors
*Microcontrollers incorporate the microprocessor, memory and input/output interfaces all on one chip
*Microcontrollers have a separate program instruction bus (Harvard architecture)
*Microcontrollers are better at small dedicated tasks, microprocessors are generally more flexible
*Introducing the PIC
microcontroller
*PIC stands for Peripheral Interface Controller
*The PIC you will be using is the 16F627
*It has flash memory which means it can be easily reprogrammed
*PICs with flash memory can generally be programmed up to 1000 times
*Peripherals
*Peripherals are interfaces or memory which are external to the microprocessor
*Carry out some research and see if you can name up to 5 peripherals
*Some peripherals
*Input and output ports
*Timers
*Clocks
*ADC converters
*USART
*DAC converters
*LCD drivers
*Buffers
