STC8 Minimum System Development Board

Overview

All I/O ports have been brought out.
I2C, SPI, USART2, USART3, and USART4 I/O ports are also separately brought out for easy module use.
To program, simply pull the BOOT button low and power on again.

LED2 blinks by default upon power-on; the blinking can be controlled via the keyLeft button.
LED3 is off by default; its on/off state can be controlled via the keyRight button.
The test program is attached and can be downloaded and programmed for testing and verification.

Image2LCD usage summary
I started to learn STM32 display pictures. I just came into contact with image2lcd and didn't know how to use it. After a few days, I finally figured out the image2lcd picture header file information:
Power supply for dot matrix display
If it is 16*16 dot matrix, how much power supply is needed, and what about 16*64? Thanks for your answer.
lpc can restart after receiving
The LPC microcontroller has two CANs. The previous program has implemented sending and receiving. This program only sends. One CAN is used. However, after sending the data received by this CAN, it can
MSP430F5529 library functions
The MSP430F5529 library function I wrote during college took me almost a year to write, from the initial 1.0 version to the final 2.+ version, and finally I had a library function that satisfied me. M
About low power consumption
I read in some materials that each module of the MSP430 series microcontroller can run independently, such as timer, input/output port, A/D conversion, watchdog, LCD display, etc. can work independent
