WebADC (analog to digital converter) is a very common peripheral used to convert an analog signal such as voltage to a digital form so that it can be read and processed by a microcontroller. ADCs are very useful in control and monitoring applications since most sensors (e.g., temperature, pressure, force) produce analogue output voltages. There is RTC GPIO support on the ESP32. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The following GPIOs can be used as an … See more GPIOs 34 to 39 are GPIs – input only pins. These pins don’t have internal pull-up or pull-down resistors. They can’t be used as outputs, so use … See more GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not … See more The ESP32 has 18 x 12 bits ADC input channels (while the ESP8266 only has 1x 10 bits ADC). These are the GPIOs that can be used as ADC and respective channels: 1. … See more The ESP32 has 10 internal capacitive touch sensors. These can sense variations in anything that holds an electrical charge, like the human skin. So they can detect variations induced when touching the GPIOs with a finger. … See more

WebFeb 3, 2024 · The TWAI controller’s interface consists of 4 signal lines known as TX, RX, BUS-OFF, and CLKOUT. These four signal lines can be routed through the GPIO Matrix to the ESP32’s GPIO pads. And that sort of seems to be backed up by their examples that make use of TWAI_GENERAL_CONFIG_DEFAULT to generate a structure with the … WebIn this Guide, we will cover ESP32’s GPIO programming, cautions, and important notes while using it.
