Based successive approximation method, offset and digital calibration module obtained correction voltage to compensate for non-linear ADC. 通过使用该ADC校准装置,在ADC处理过程中可以校准各个参考电压并且可以使用相应的校正电压调整参考电压. By using the ADC calibration device, the ADC process to calibrate ...
我们都知道 ADC 的校准函数为:HAL_ADCEx_Calibration_Start() 但是当我使用这个函数时候,居然出错了,如下图: 提示调用的参数太少了(确定出错是我编译过后发现的),提示函数调用参数太少了,这就奇怪了,于是我进入看看函数原型: 这里可以看到,怎么多了一个参数(上面确实有解释说明,应该填写什么),但是当时我第一反应...
HAL_StatusTypeDef hal_adcex_calibration_start(ADC_HandleTypeDef* hadc, uint32_t ADC_CalibrationType); ``` 参数说明: - hadc:指向ADC外设的句柄。 - ADC_CalibrationType: ADC校准类型,可以是以下值之一: - ADC_CALIB_OFFSET:偏移校准 - ADC_CALIB_GAIN:增益校准 返回值: - HAL_OK:校准启动成功 -其他...

ADC 增益误差Gain Error详解及校准Calibration 增益误差是指ADC实际传输特性曲线和理想传输特性曲线的偏差程度。增益误差的单位是%FSR（满量程值）。如果没有校准，那么增益误差会限制信号输出的准确性。例如，一个16位的ADC，增益误差为±0.2%，意味着在最大ADC输出时，会带来7位（131）的误差。如上图所示，红线为...

When the ADC pin is connected to AGND, the readout value is 14 but I expect 0. I think there is need for calibration. To calibrate, I think there is need for a schematic. I did my first try with the simplest schematic I could imagine, like this: With above values (14 and 4083)...
