ADC输入校准寄存器ADCOFFTRIM的如何使用啊?
Seven Han:
The ADC_cal() routine is programmed into TI reserved OTP memory by the factory. The boot ROMautomatically calls the ADC_cal() routine to initialize the ADCREFSEL and ADCOFFTRIM registers withdevice specific calibration data. During normal operation, this process occurs automatically and no actionis required by the user.
ADCREFSEL and ADCOFFTRIM registers初始化由boot ROM调用 ADC_cal函数实现
