Can you recognize that this is the same board as the previous post? Well now it has all the components anybody would ever need to learn every aspect of coding on this platform, really! It is a very simple and yet uses almost every pin/feature of the 8051. It is very cheap to build and covers the whole development life cycle of the controller just like for a production circuit, because you need to take out the chip and burn the new firmware then put it in again.
Features:
- 40-pin DIP controller 8052 or similar - ATmel being used here
- 12 MHz crystal
- Reset
- Buzzer
- LEDs on one port
- DIP switches on one port controlling the LEDs
- 5V regulator (can be powered by a 9V standard battery)
- 2 digit 7-segment display
- 2 push buttons, one to increment and one to decrement the number displayed
- RS-232 serial port can update numeric display and buzzer frequency, also send data of dip and push buttons to PC
- A simple PC application can show status of all connected peripherals
