adc_oneshot_unit_ctx_t *units[SOC_ADC_PERIPH_NUM];:这是一个指向adc_oneshot_unit_ctx_t类型的指针数组,用于存储ADC单元的上下文信息。SOC_ADC_PERIPH_NUM是一个宏定义,表示ADC外设的数量。 int apb_periph_ref_cnts;:这是一个整型变量,用于记录使用APB_SARADC外设的ADC单触发模式芯片的引用计数。 看这个...
sizeof(adc_oneshot_unit_ctx_t):每个元素的大小。这里,我们使用sizeof操作符来获取adc_oneshot_unit_ctx_t类型数据的大小(以字节为单位),然后把它作为calloc函数的第二个参数。这意味着我们想要分配一块能够存储一个adc_oneshot_unit_ctx_t类型数据的内存。 ADC_MEM_ALLOC_CAPS:内存分配器的容量属性。这通常用...

设置ADC 的初始配置后,使用adc_oneshot_new_unit()准备好的adc_oneshot_unit_init_cfg_t.如果分配成功,该函数将返回 ADC 单元句柄。 里面的返回值 该函数可能会因参数无效、内存不足等各种错误而失败。具体来说,当要分配的ADC实例已经注册时,该函数将返回ESP_ERR_NOT_FOUND错误。可用 ADC 的数量由 记录SOC_AD...

with the 4th param set 0. Value of efuse returns 3, but adc_chars.vref remains 0. Not sure if it is a problem of my chip so I turned to the native exampleesp-idf\examples\peripherals\adc\oneshot_read\main\oneshot_read_main.cbut it confirms that my chip supports a calibration scheme...
