## Hardware {#esp32s3_pros3_hardware}
|
||||
|
||||
This section describes
|
||||
|
||||
- the [MCU](#esp32s3_pros3_mcu),
|
||||
- the default [board configuration](#esp32s3_pros3_board_configuration),
|
||||
- the [board pinout](#esp32s3_pros3_pinout).
|
||||

||||

|
||||
|
||||
### MCU {#esp32s3_pros3_mcu}
|
||||
|
||||
Most features of the board are provided by the ESP32-S3 SoC. For detailed
|
||||
information about the ESP32-S3 SoC variant (family) and ESP32x SoCs,
|
||||
see section \ref esp32_mcu_esp32 "ESP32 SoC Series".
|
||||
|
||||
[Back to table of contents](#esp32s3_pros3_toc)
|
||||
|
||||
### Board Configuration {#esp32s3_pros3_board_configuration}
|
||||
|
||||
ESP32 ProS3 boards have no special hardware on board with the exception
|
||||
of a single pin RGB-LED WS2812B that uses a special bit-oriented protocol to
|
||||
control the RGB-LED by 24-bit RGB values which is not supported yet.
|
||||
|
||||
Most GPIOs are broken out on the board for flexibility. The default board
|
||||
configuration provides:
|
||||
|
||||
- 10 x ADC channels at maximum
|
||||
- 1 x SPI
|
||||
- 1 x I2C
|
||||
- 1 x UART
|
||||
- 2 x PWM, 4 channels each
|
||||
- 1 x RGB-LED
|
||||
|
||||
For flexibility, some GPIOs are used in different peripheral configurations,
|
||||
but they can only be used for one peripheral at a time. For example, GPIO9
|
||||
is used in the ADC channel definition and the definition of the SCL signal
|
||||
for I2C_DEV(0).
|
||||
|
||||
This is possible because GPIOs are only used for a specific peripheral
|
||||
interface when either
|
||||
|
||||
- the corresponding peripheral module is used, e.g. `periph_i2c`, or
|
||||
- the corresponding init function is called, e.g. `adc_init`.
|
||||
|
||||
That is, the purpose for which a GPIO is used depends on which module
|
||||
or function is used first.
|
||||
|
||||
For example, if module `periph_i2c` is not used, the GPIOs listed in I2C
|
||||
configuration can be used for the other purposes, that is, GPIO9 can be
|
||||
used as ADC channel.
|
||||
|
||||
The following table shows the default board configuration, which is sorted
|
||||
according to the defined functionality of GPIOs. This configuration can be
|
||||
overridden by \ref esp32_application_specific_configurations
|
||||
"application-specific configurations".

The following figure shows the pinout as configured by board definition.

|
||||
## Flashing the Device {#esp32s3_pros3_flashing}
|
||||
|
||||
Since the board does not have a USB-to-Serial chip, the easiest way to flash
|
||||
the board is using the USB Serial/JTAG interface. Just connect the board to
|
||||
your host computer and use the following command:
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
BOARD=esp32s3-pros3 make flash ...
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
@note Usually the make system resets the board before flashing to enable the
|
||||
USB Serial/JTAG interface. In some special cases this reset does not work so
|
||||
that the programmer cannot connect to the board and the flashing is aborted
|
||||
with a timeout:
|
||||
```
|
||||
Serial port /dev/ttyACM0
|
||||
Connecting...
|
||||
...
|
||||
serial.serialutil.SerialTimeoutException: Write timeout
|
||||
```
|
||||
This can happen for example if the board is not yet flashed with RIOT or the
|
||||
USB interface is used for another purpose. In this case, restart the board
|
||||
manually in download mode by pressing and releasing the RESET button while
|
||||
holding down the BOOT button. In download mode, the USB Serial/JTAG interface is
|
||||
always available.
|
||||
|
||||
Alternatively, an external USB-to-Serial adapter can be used. In this case,
|
||||
the USB-to-Serial adapter has to be connected to TxD (GPIO43) and RxD (GPIO44)
|
||||
of the UART0 interface. Before RIOT can be flashed, the board has to be
|
||||
switched to download mode. To do this, press and release the RESET button
|
||||
while holding down the BOOT button. Once the board is in download mode, use
|
||||
the following command to flash RIOT:
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
BOARD=esp32s3-pros3 make flash ...
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
For detailed information about ESP32-S3 as well as configuring and compiling
|
||||
RIOT for ESP32-S3 boards, see \ref esp32_riot.

|
||||
|
||||
## Using STDIO {#esp32s3_pros3_stdio}
|
||||
|
||||
Since the board does not have a USB-to-Serial chip, the USB Serial/JTAG
|
||||
interface is used by default for the STDIO (module `stdio_usb_serial_jtag`)
|
||||
which provides an USB CDC ACM interface.
|
||||
|
||||
If the USB port is used by the USBUS stack or the tinyUSB stack, implicitly
|
||||
the module `stdio_cdc_acm` or `stdio_tinyusb_cdc_acm` is used for the STDIO
|
||||
via the USB CDC ACM interface.
|
||||
|
||||
Alternatively, the UART interface could be used with an external USB-to-Serial
|
||||
adapter. Simply add `stdio_uart` to the list of used modules for this purpose:
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
BOARD=esp32s3-pros3 USEMODULE=stdio_uart make flash ...
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
