I believe that the ADC input is limited to 0-1V range. To measure in the range 0-3.3V, board manufacturers put a resistor divider on the pin, to map the range. However, resistors have tolerance, the most common being 5%. Use of the ADC input should always be calibrated for each spe...
I want to ask for I set the sample rate = 250 Hz in ADC function. Then I want to set up a timer in the BLE Code that can call the ADC Function by interrupt every 1/250 sec to get the ADC value. How to create this timer? I have found like SysTick, CTimer, ... But I didn...

Look in file adc_common.cIn ADC2, there're two locks used for different cases: lock shared with app and Wi-Fi: ESP32: When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed. ESP32S2: The controller's control over the ...
对于捕获流,GetPosition方法检索记录位置,这是要通过麦克风插孔接收并由 ADC 捕获的最新样本的字节偏移量。 某些音频硬件包含一个位置寄存器,用于跟踪每个 DAC 或 ADC 中当前样本的字节偏移量,在这种情况下,GetPosition方法只需检索相应流的位置寄存器的内容。 其他音频硬件只能向音频缓冲区提供 DMA 指针...
for the attenuation, nothing worked out. The Joystick takes 5V. However, I have tested it, and it also gives 5V from the analog output pin. About the resolution of the ADC, even if I did not use the appropriate value, at least it will give some value, not '-1'. This is the ...

We know that LVDS needs input termination and with the value of "Differential", as above image. We applied this constrain for ADC output pairs. They run well. So we have another type LVDS pairs input, which are not from external ADC chips. They come from comparator devices output. F...
