Introduction to Embedded System
- P89v51rd2 - 8 bit micro controller,and its features are,
- 32 IO Pins available to communicate with physical device
- 2 -16 Timer and Counter
- 2 External Interrupt
- Inbuilt PWM Controls
- I2C Communication
- SPI Communication
- Support ISP and ICP
- P89v51RD2 Pin out,
- Connection of VDD,GROUND and Crystal Connection,
- VDD and Ground:
Every Electronic circuits without power supply doesn't work i.e VCC and Ground.Following VCC and Ground connection will be connected like below diagram.
power supply
- Crystal Connection:
Micro controller are working depending on the applied clock pulse.This clock pulse are generated by crystal oscillator and it is connected to circuit like below diagram.
