CH347-Flash-Programmer

Based on the simplified version modified by CH347-"Kill You 3000" high-speed four-mode programmer + serial port/JTAG debugging equipment- Jialichuang EDA open source hardware platform (oshwhub.com), the mode is set to mode 1, which is only used to flash the BIOS , supports 3.3V 1.8VFlash, and can be switched freely with a sliding switch.
The finished product is as follows: verified and working.
 
If the programmer is connected and recognized correctly, the device manager will display as follows:

software recognizes Flash and uses the interface as follows. The reading speed is really fast. It only takes more than 11 seconds to read a 32MB flash.
Why is the read speed so fast? I simply checked the speed, and it turned out to be 62.5MHz, which is too fast.
 
It only takes 183 seconds to completely program a 32MB Flash.
 
Note: 3.3V can be used normally, but it can also be used when switching to 1.8V. However, the CS/CLK/DI/DO voltage is still 3.3V. A conversion chip needs to be added here, which needs to be solved.
