PMW3360-3389-PAW3395_STM32-CH32-APM32

you need to open with RAW button!

This is my ACFUN Home page: https://www.acfun.cn/u/7503062

software: keil 5 hardware:

1. MCU: STM32(M0/M3)/CH32(Risc-v)/APM32(M4)
2. Sensor: PMW3360-DM\PMW3389-DM\PAW3395
3. five buttons with hardware debounce
4. Encoder

1. SOF number change, mean this a new USB frame, and then start timer stick about 77us, couse the PMW3360 SPI clock is 2Mbps, PAW3395 might be count stick about 10us, HAL lib might have huge send interval!
2. Get datas at last frame end, USB send datas at current frame begin.

M0 core MCU is not enough for mouse sensor! If you wanna find a TSSOP20 package, I recommend CH32V305FBT6, 144Mhz and HS USB 2.0 olny pay for $2；

the progam just a demo, you need to modify it! you can download full project from: https://pan.baidu.com/s/1XnpNVsO6pANIwLP8uDlTRA?pwd=3378
