1、Readme:For ARMBefore using this code:- Make sure I2C address is matching datasheet- If i2c driver existed, then just ignore qnio.c/h- Modify QND_Deley(ms) to get accurate platform related miliseconds delay, otherwise all chips functionality may not working properly- Detail please read related doc or
