mcp2221_hidapi：到MCP2221的USB C代码接口USB到I2C

## mcp2221(A) hidapi C-library Yet another lib for MCP2221 https://www.microchip.com/wwwproducts/en/MCP2221A Inspired by: - https://github.com/nonNoise/PyMCP2221A - https://github.com/zkemble/libmcp2221 First one is only python, 2nd one I got into memory issues (unstable). Therefore this lib, which is a bare minimum variant. ### Installation ### Building #### MinGW gcc (win10) Depends on `hidapi` library. A copy of https://github.com/libusb/hidapi dll and header file are present in this repo. ```sh make libmcp2221_hidapi.dll ``` Deploy both `dll` files. #### linux gcc (ubuntu 20)
