ESP32-C6-DevKitC-1
|
||
|
|
==================
|
||
|
|
|
||
|
|
ESP32-C6-DevKitC-1 is an entry-level development board based on ESP32-C6-WROOM-1(U),
|
||
|
|
a general-purpose module with a 8 MB SPI flash. This board integrates complete Wi-Fi,
|
||
|
|
Bluetooth LE, Zigbee, and Thread functions. You can find the board schematic
|
||
|
|
`here <https://espressif-docs.readthedocs-hosted.com/projects/espressif-esp-dev-kits/en/latest/_static/esp32-c6-devkitc-1/schematics/esp32-c6-devkitc-1-schematics_v1.2.pdf>`_.
|
||
|
|
|
||
|
|
Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing.
|
||
|
|
Developers can either connect peripherals with jumper wires or mount ESP32-C6-DevKitC-1 on
|
||
|
|
a breadboard.

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 IO9. 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 on-board LED that indicates the presence of power.
|
||
|
|
Another WS2812 LED is connected to GPIO8 and is available for software.
|
||
|
|
|
||
|
|
Current Measurement
|
||
|
|
===================
|
||
|
|
|
||
|
|
The J5 headers on the ESP32-C6-DevKitC-1 can be used for measuring the current
|
||
|
|
drawn by the ESP32-C6-WROOM-1(U) module:
|
||
|
|
|
||
|
|
- Remove the jumper: Power supply between the module and peripherals on the
|
||
|
|
board is cut off. To measure the module's current, connect the board with an
|
||
|
|
ammeter via J5 headers;
|
||
|
|
- Apply the jumper (factory default): Restore the board's normal functionality.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
When using 3V3 and GND pin headers to power the board, please remove the J5 jumper,
|
||
|
|
and connect an ammeter in series to the external circuit to measure the module's current.

Configurations
|
||
|
|
==============
|
||
|
|
|
||
|
|
All of the configurations presented below can be tested by running the following commands::
|
||
|
|
|
||
|
|
$ ./tools/configure.sh esp32c6-devkit:<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.
|
||
|
|
|
||
|
|
coremark
|
||
|
|
--------
|
||
|
|
|
||
|
|
This configuration sets the CoreMark benchmark up for running on the maximum
|
||
|
|
number of cores for this system. It also enables some optimization flags and
|
||
|
|
disables the NuttShell to get the best possible score.
|
||
|
|
|
||
|
|
.. note:: As the NSH is disabled, the application will start as soon as the
|
||
|
|
system is turned on.
|
||
|
|
|
||
|
|
nsh
|
||
|
|
---
|
||
|
|
|
||
|
|
Basic configuration to run the NuttShell (nsh).
