编译报错does not name a type

Code: [Select all] [Expand/Collapse]

1. #include "esp_adc_cal.h"
2. static esp_adc_cal_characteristics_t *adcChar;
3. adcChar=(esp_adc_cal_characteristics_t *)calloc(1, sizeof(esp_adc_cal_characteristics_t));

'adcChar' does not name a type
试过很多方法，都不能解决

你具体咋整的？IDF 版本？再提供多些代码？再提供多些 log？

Code: Select all

#include "esp_adc_cal.h"

void app_main(void)
{
    static esp_adc_cal_characteristics_t *adcChar;
    adcChar = calloc(1, sizeof(esp_adc_cal_characteristics_t));
}

这样最多有个 warning。

用的时arduino，现在换成analogread（）读取adc数值了
