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
T0
IO4/D12
T1
IO0/D5
T2
IO2/D9 (Connected to the on-board LED, and can't be used to test the touch sensing function)
T3
IO15/A4
T4
IO13/D7
T5
IO12/D13
T6
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.
