Preparation:

FireBeetle 2 ESP32-E (https://www.dfrobot.com/product-2195.html) (SKU: DFR0654) ×1

Function Description:

FireBeetle 2 ESP32-E provides the function of capacitive touch sensing with a total of 7 touch pins available, labeled as T0 to T6. The

corresponding pin numbers are shown in the table below:

Touch Sensor

Pin Number

IO4/D12

IO0/D5

IO2/D9 (Connected to the on-board LED, and can't be used to test the touch sensing function)

IO15/A4

IO13/D7

IO12/D13

IO14/D6

PinMode setting is not required. The touchRead() returns a value within 0-255. The larger the touch intensity, the smaller the returned value.

To obtain the GPIO status of the touch sensor, just need to call the touchRead function, whose function prototype is: uint16_t

touchRead(uint8_t pin).

Sample Code:

Program function: Burn the routine, use the pin IO4/D12 as a touch button, and return the touch value through the serial monitor.
