Presentation Transcript

  1. Microcontrollers Basic information

  2. 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 Differences compared to microprocessors

  3. 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 Introducing the PIC microcontroller

  4. 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 Peripherals

  5. Input and output ports • Timers • Clocks • ADC converters • USART • DAC converters • LCD drivers • Buffers Some peripherals

  6. Inside the PIC 16F627 Datasheet on Bluepill http://ww1.microchip.com/downloads/en/DeviceDoc/40300C.pdf

  7. PIC 16F627 pin connections

  8. Your first PIC circuit
