STM32F303xC系列ADC校准一直不通过
郭郭1231654 提问时间: 2023-10-01 10:39:48 / 未解决| 本来的硬件平台是STM32F303VC,ADC校准能通过。换成STM32F303CC，校准就不行了，程序用的老的固件库。ADC的校准需要什么条件才能成功。初始化代码如下： ADC_InitTypeDef ADC_InitStructure; ADC_CommonInitTypeDef ADC_CommonInitStructure; /* Configure the ADC clock */ RCC_ADCCLKConfig(RCC_ADC12PLLCLK_Div1); // RCC_AHBPeriphResetCmd(RCC_AHBPeriph_ADC12,ENABLE); /* Enable ADC1 clock */ RCC_AHBPeriphClockCmd(RCC_AHBPeriph_ADC12, ENABLE);

debug_log("ADC2 Calibration Value %d",calibration_value_2); } // /* ADC Dual mode configuration */ ADC_CommonInitStructure.ADC_Mode = ADC_Mode_RegSimul; ADC_CommonInitStructure.ADC_Clock = ADC_Clock_AsynClkMode;

用CubeMX下载的芯片包里的例程就是固件库的
