1)SMT32的ADC是逐次逼近(successive approximation),在STM32技术参考手册的ADC部分有这样一句话:“The 12-bit ADC is a successive approximation analog-to-digital converter”
2)我不懂ADC的原理,所以也不能理解自动矫正的原理,在STM32技术参考手册的ADC部分有这样一句话,可以作为参考:“The ADC has an built-in self calibration mode. Calibration significantly reduces accuracy errors due to internal capacitor bank variations. During calibration, an error-correction code (digital word) is calculated for each capacitor, and during all subsequent conversions, the error contribution of each capacitor is removed using this code.”
