51 Microcontroller LED Control and Flowing LED Tutorial
1. Lightign All LEDs on P2 Port
Using an STC89C52-based development board (e.g., model A2), start by configuring Keil: enable "Create HEX File" in output settings. The microcontroller runs code in an infinite loop, so use while(1).
From the schematic, LEDs are common-anode (connected to P2). Setting P2 to 0x00 (low voltage) lights all ...
