STC8H8K64U Development Board

0. 4 independent LED channels
; 1. Two RS-485 channels
; 2. One I2C channel for OLED and BM8563 microcontroller
; 3. One SPI channel for SPI Flash and TF card;
4. 8-digit LED display;
5. Matrix keyboard expansion;
6. One NTC temperature sensor;
7. One photoresistor
; 8. One adjustable potentiometer;
9. One infrared receiver;
10. One passive buzzer;
11. One parallel LCD interface;
 
1. Reference source selectable 2.5V or 3.3V.
2. With ISP software, direct USB download and simulation are possible without a UART bridge chip.
3. The matrix keyboard interface outputs 4 PWM channels, suitable for motor-related experiments.
4. In addition to the OLED interface, an 8-bit LCD interface is also included
 
, suitable for microcontroller beginners to conduct experiments and easily verify various basic drivers.
 
Version 1.0 had issues with the op-amp power supply being reversed and the potentiometer position interfering with the buttons; P3.2 was not connected with a pull-up resistor. Version 1.1 has fixed these issues.
 
The attached file is a simple example that displays the potentiometer and photoresistor's ADC on a digital tube; the program uses a 22.1184MHz IRC.
