Driver for LED

Getting Started

Requirements

• Keil IDE
• Flash Magic
• 8051 microcontroller
• LEDs (x8)

Installing

1. Connect LEDs to Port 0 of the 8051 microcontroller
2. Open Keil and create new project
   • Choose Philips P89V51RD2 database
3. Add led.c file to Source Group
   • Edit led.c's main function: P0 = 0xNN
4. Build target
5. Use Flash Magic to write the resulting hex file to the 8051 microcontroller

Example

We can turn the 3rd, 6th, and 7th LEDs on by programming Port 0 to 0x26, which is 00100110 in binary. We write P0 = 0x26 in led.c's main function, build the target, and use Flash Magic to write the hex file to the microcontroller.
