Main connector header
|
||||
=====================
|
||||
|
||||
The Zephyr m5stack_stamps3 board can be used on various applications. It
|
||||
therefore publishes a header definition to be used in different shields:
|
||||
:dtcompatible:`m5stack,stamps3-header`.
|
||||
|
||||
.. figure:: img/m5stack_stamps3_header.webp
|

:align: center
|
||||

|
||||
:width: 400 px
|
||||
|
||||
M5Stack StampS3 connector header
|
||||
|
||||
Following interfaces are being exported for this header:
|
||||
|
||||
- ``m5stack_stamps3_clkout0``: PWM output with 2 channels (0 and 2).
|
||||
- ``m5stack_stamps3_spilcd``: SPI interface for interfacing LCDs. Consists of a
|
||||
CLK, MOSI and CS signal.
|
||||
- ``m5stack_stamps3_i2c0`` and ``m5stack_stamps3_i2c1``: I2C interfaces (SDA, SCL).
|
||||
- ``m5stack_stamps3_uart0``: UART interface (RXD, TXD).
|
||||
- ``m5stack_stamps3_header``: All GPIOs are of course accessible via main header
|
||||
definition.

Power supply
|
||||
============
|
||||
|
||||
M5Stack StampS3 requires a single 5V input power supply. The module internally
|
||||
features a DCDC (MUN3CAD01-SC) to generate the 3.3V needed for the MCU.
|
||||
|
||||
The **EN** signal (Pin 22) is an active low signal to enable the **3V3** power
|
||||
supply. If this pin is pulled low this main 3.3V power supply for the MCU will be
|
||||
deactivated. It is internally equipped with a pull-up and can hence be left open
|
||||
if unused.
|
||||
|
||||

|
||||
*****************************
|
||||
|
||||
Before powering up your M5Stack StampS3, please make sure that the board is in good
|
||||
condition with no obvious signs of damage.
|
||||
|
||||
System requirements
|
||||
===================
|
||||
|
||||
Prerequisites
|
||||
-------------
|
||||
|
||||
Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command
|
||||
below to retrieve those files.
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
west blobs fetch hal_espressif
|
||||
|
||||
.. note::
|
||||
|
||||
It is recommended running the command above after :file:`west update`.
|
||||
|
||||
Building & Flashing
|
||||
-------------------
|
||||
|
||||
Build and flash applications as usual (see :ref:`build_an_application` and
|
||||
:ref:`application_run` for more details).
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: m5stack_stamps3
|
||||
:goals: build
|
||||
|
||||
The usual ``flash`` target will work with the ``m5stack_stamps3`` board
|
||||
configuration. Here is an example for the :ref:`hello_world`
|
||||
application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: m5stack_stamps3
|
||||
:goals: flash
|
||||
|
||||
The baud rate of 921600bps is set by default. If experiencing issues when flashing,
|
||||
try using different values by using ``--esp-baud-rate <BAUD>`` option during
|
||||
``west flash`` (e.g. ``west flash --esp-baud-rate 115200``).
|
||||
|
||||
You can also open the serial monitor using the following command:
|
||||
|
||||
.. code-block:: shell
|
||||
|
||||
west espressif monitor
|
||||
|
||||
After the board has automatically reset and booted, you should see the following
|
||||
message in the monitor:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx *****
|
||||
Hello World! m5stack_stamps3
|
||||
|
||||
Debugging
|
||||
---------
|
||||
|
||||
M5Stack StampS3 exports a JTAG-interface via Pins 19 (MTCK), 21 (MTDO), 23
|
||||
(MTDI), 25 (MTMS).
|
||||
|
||||
.. note::
|
||||
|
||||
Please note that additional JTAG equipment is needed to utilize JTAG. Refer to
|
||||
the ESP32S3 datasheet and the M5Stack StampS3 documentation for details.
