/* GPIO pins definitions

|
|
* pin layout is compatible with ESP32-CAM module for prototyping
|
|
* LEDs aren't avaible on ESP32-CAM but DEBUG LED (Camera connector)
|
|
*
|
|
* on ESP32-CAM the following pins are already used:
|
|
* - CSI_MCLK (GPIO0)
|
|
* - U0TXD (GPIO1)
|
|
* - U0TXD (GPIO3)
|
|
* - FLASH (GPIO4)
|
|
*
|
|
* on ESP32-PICO-D4, the following pins are used for connecting the
|
|
* embedded flash:
|
|
* - CLK (GPIO6)
|
|
* - SD0 (GPIO7)
|
|
* - SD1 (GPIO8)
|
|
* - CMD (GPIO11)
|
|
* - GPIO16
|
|
* - GPIO17
