==============
ESP32-2432S028
==============
The ESP32-2432S028 is a development board based on an ESP32-WROVER-32 module. It is designed for a
wide range of applications, particularly in the field of the Internet of Things (IoT).

:align: center
ESP32-2432S028 board layout - back
Features
========
- LCD screen (2.8 inch)
- MicroSD card slot
- RGB LED
- Audio
- Light Dependent Resistor (LDR)
Most of I/O pins are broken out to the boards, but from the back side of the board, there are
some pins available are separated into two connectors femme JST 1.28 mm 4P.
Serial Console
==============
UART0 is, by default, the serial console. It connects to the on-board
CH340 converter.
Buttons and LEDs
================
Board Buttons
-------------
There are two buttons labeled BOOT and RST. The RST button is not available
to software. It pulls the chip enable line that doubles as a reset line.
The BOOT button is connected to IO0. On reset it is used as a strapping
pin to determine whether the chip boots normally or into the serial
bootloader. After reset, however, the BOOT button can be used for software
input.
Board LEDs
----------
There is one RGB LED available.
Pin Mapping
===========
===== ========================= ==========
Pin Signal Notes
===== ========================= ==========
0 BOOT Button
2 LCD Reset
4 RGB LED Green
12 LCD MISO
13 LCD MOSI
14 LCD Clock
15 LCD CS
16 RGB LED Blue
17 RGB LED Red
21 LCD Backlight
26 Audio Out
34 LDR
===== ========================= ==========
Configurations
==============
All of the configurations presented below can be tested by running the following commands::
$ ./tools/configure.sh esp32-2432S028:<config_name>
$ make flash ESPTOOL_PORT=/dev/ttyUSB0 -j
Where <config_name> is the name of board configuration you want to use, i.e.: nsh, buttons, wifi...
Then use a serial console terminal like ``picocom`` configured to 115200 8N1.
lvgl
----
This is a demonstration of the LVGL graphics library running on the NuttX LCD
driver. You can find LVGL here::
https://www.lvgl.io/
https://github.com/lvgl/lvgl
This configuration uses the LVGL demonstration at `apps/examples/lvgldemo`.
nsh
---
Basic NuttShell configuration (console enabled in UART0, exposed via
USB connection by means of CH340 converter, at 115200 bps).

* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a
* mode enumeration value, a set of DIP switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
