16-bit LED STC89C52 rocker

 
Overview

1. The microcontroller used is 51 microcontroller; 2. The font uses modulo software; 3. Using IN4170 diode can reduce the resistance and does not need to be pulled up on the P0 port; 4. The program can be downloaded through the built-in TTL adapter cable, and the data cable during downloading RXD is connected to TXD port, TXD is connected to RXD; 5. Please refer to the attachment for the program; //-- Huan--

For the sake of intuition, let’s sort the above dot matrix according to the PCB wiring method:

  1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4
P00 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0
P01 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0
P02 1 1 1 1 1 1 0 0 1 0 0 0 0 0 0 0
P03 0 0 0 0 0 1 0 0 1 1 1 1 1 1 0 0
P04 0 1 0 0 0 1 0 1 0 0 0 0 0 1 0 0
P05 0 1 0 0 0 1 1 0 0 1 0 0 1 0 0 0
P06 0 0 1 0 1 0 0 0 0 1 0 0 0 0 0 0
P07 0 0 1 0 1 0 0 0 0 1 0 0 0 0 0 0
P20 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 0
P21 0 0 1 0 1 0 0 0 0 1 0 0 0 0 0 0
P22 0 0 1 0 0 1 0 0 1 0 1 0 0 0 0 0
P23 0 1 0 0 0 1 0 0 1 0 1 0 0 0 0 0
P24 1 0 0 0 0 0 0 1 0 0 0 1 1 0 0 0
P25 0 0 0 0 0 0 0 1 0 0 0 0 1 0 1 0
P26 0 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0
P27 0 0 0 0 1 1 0 0 0 0 0 0 0 1 0 0

1 means on, 0 means LED is off; after removing 0, it is the word "happy"
