You can define the pins the same way in firmware also. The following picture shows the pinout diagram of the ESP32 DEVKIT V1 DOIT board. In your version of the ESP32 development kit, each GPIO pin may be exposed on a different pin number....
* to use it as generalized input, * firstly declair it as pullup input */ gpio_config_t conf; conf.mode = GPIO_MODE_INPUT; conf.pull_up_en = GPIO_PULLUP_ENABLE; conf.pull_down_en = GPIO_PULLDOWN_DISABLE; conf.intr_type = GPIO_INTR_DISABLE; conf.pin_bit_mask = 1LL << 13;...
Although you can define the pins properties on the software, there are pins assigned by default as shown in the following figure (this is an example for theESP32 DEVKIT V1 DOIT boardwith 36 pins – the pin location can change depending on the manufacturer). Additionally, there are pins wit...
Assign the correct pinout depending on your ESP32 dev board There are several development boards based on the ESP32 chip, make sure you assign the correct pin numbers to the signals that interface with the TFT display board. Its recommended to use a predefined configuration below, but you can...
ESP32-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding.
