To solve the problem that TMS320F2812 has a accuracy deviation in data acquisition, even sometimes the sampling value is far from the actual value, a method of ADC correction algorithm is designed, which can realize the compensation in gain deviation and offset deviation. Finally, the compensation of ADC sampling accuracy was completed combining with a simple hardware circuit.
