ESP32 ADC 误差大 esp32 adc精度 概述 ESP32集成了两个12位SAR(逐次逼近寄存器:Successive Approximation Register)ADC,总共支持18个测量通道(支持模拟的引脚)。 ADC驱动器API支持ADC1(8个通道,连接到GPIO 32-39)和ADC2(10个通道,连接到GPIO 0、2、4、12-15和25-27)。但是,ADC2的使用对应用程序有一些限制:...
Unlike the Arduino UNO where analog pins are limited to 6, the ESP32 has 18 channels. You can view all the analog pins in the ESP32 pinout diagram above. Digital to Analog Converter Pins Digital to Analog Converter (DAC) pins enable the generation of analog output signals. This feature is...
Re: Digital pins usable for interrupts Postbybobtidey»Sun Oct 07, 2018 9:56 pm I believe that any GPIO that can be used for normal input can be used as an interrupt source. All GPIO events get handled by a common single low level interrupt handler. In the esp32 Arduino the attachIn...
All GPIO pins of ESP32 can be used as digital input pins. But ESP32 has four GPIO pins which can be used as digital input pins only. They cannot be configured as digital output pins. Also, unlike other GPIO pins, these pins do not have internally connected push-pull resistors. Therefore...
