When working in continuous mode, hardware will continuously trigger ADC to do conversions. On esp32s2, 2 bytes will be generated per conversion. Prior to this commit, driver assumes 4 bytes per conversion (on s2). This commit fixed this issue.Loading...
So I'm essentially looking to create adc_continuous_pause/resume() functions .. something like:Code: Untitled.c Select allesp_err_t adc_continuous_pause(adc_continuous_handle_t handle) { // Stop ADC hardware without deinitializing adc_hal_digi_stop(&handle->hal); ...

以下是如何在连续模式下使用 ADC 的示例。 // Define how many conversion per pin will happen and reading the data will be and average of all conversions #define CONVERSIONS_PER_PIN 5 // Declare array of ADC pins that will be used for ADC Continuous mode - ONLY ADC1 pins are supported //...
Hi, I am working on a project where I need to get 10kHz sample rate i.e. 10,000 sample in 1 second on ADC pin using DMA in ESP32. I have tried this using ADC in continuous mode example code. But I am getting only 120-150 approx. samples in 1 second. ...
continuous_read(NULL); 函数,测试结果如下: 1.2 单次采样 单次采样比较简单,也是直接在上面的样例中修改,下面直接上修改后的测试代码: static void single_read(void *arg) { // esp_err_t ret; // int adc1_reading[3] = {0xcc}; int adc1_reading[1] = {0xcc}; ...
1Hz is the slowest i can do with my Function Generator. I get the same ADC jumps of Value also when i sample with ADC Continuous Mode Driver. There is never any 2,3,4,5,6,7,8,9,10,11,12,13,14 values. Only 1,15,16,17 and combinations of the last ones. ...
