// ESP32-S3 GPIO layout
/* see https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/gpio.html
* The ESP32-S3 chip features 45 physical GPIO pins (GPIO0 ~ GPIO21 and GPIO26 ~ GPIO48). Each pin can be used as a general-purpose I/O
* Strapping pins: GPIO0, GPIO3, GPIO45 and GPIO46 are strapping pins. For more infomation, please refer to ESP32-S3 datasheet.
* Serial TX = GPIO43, RX = GPIO44; LED BUILTIN is usually GPIO39
* USB-JTAG: GPIO 19 and 20 are used by USB-JTAG by default. In order to use them as GPIOs, USB-JTAG will be disabled by the drivers.
* SPI0/1: GPIO26-32 are usually used for SPI flash and PSRAM and not recommended for other uses.
* When using Octal Flash or Octal PSRAM or both, GPIO33~37 are connected to SPIIO4 ~ SPIIO7 and SPIDQS. Therefore, on boards embedded with ESP32-S3R8 / ESP32-S3R8V chip, GPIO33~37 are also not recommended for other uses.

* https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/adc_oneshot.html
* ADC1: GPIO1 - GPIO10 (channel 0..9)
* ADC2: GPIO11 - GPIO20 (channel 0..9)
* adc_power_acquire(): Please do not use the interrupt of GPIO36 and GPIO39 when using ADC or Wi-Fi and Bluetooth with sleep mode enabled. As a workaround, call adc_power_acquire() in the APP.
* Since the ADC2 module is also used by the Wi-Fi, reading operation of adc2_get_raw() may fail between esp_wifi_start() and esp_wifi_stop(). Use the return code to see whether the reading is successful.
