CW32 Voltage and Current Meter

Overview

1. Project Function Introduction:
This is a voltage and current meter designed based on the LCSC CW32F030C8T6 development board. It can collect and display voltage and current, and has reserved interfaces for measurement using common multimeter connectors.

2. Project Attributes
: This project is a replica
of the LCSC CW32 voltage and current meter training program, with some improvements:
1. Some plug-in components in the training program have been replaced with surface-mount components;
2. The power supply section uses a CH224K for induced power supply (due to initial failure, this part did not work properly and was replaced with a 9V dry cell battery).

3. Open Source License:

FPGA uses FLASH in DSP?
As the title says, generally FPGAs have to use external FLASH chips to store programs. To save costs, I wonder if it is possible to use the internal FLASH of the DSP on the same board to store program

Wince s3c2440 uses COM1 to read and write normally, but COM3 and COM4 cannot
COM3 and COM4 can be opened. However, the data sending is abnormal and no data output is seen. At first, it was stuck on WriteFile. Later, I added parameters such as timeout interval, and it can retur
Please help me find out what is wrong with my program?
Please help me find out if there is anything wrong with the program I wrote. The current situation is that after downloading it to the microcontroller, the first digital tube displays a zero, and then
