** Project Setup
|
|
Clone the repository
|
|
#+BEGIN_SRC shell
|
|
git clone git@gitea.rkcf.me:rkcf/esp32-sequencer.git
|
|
cd esp32-sequencer
|
|
#+END_SRC
|
|
|
|
Source idf path. Assumes [[https://docs.espressif.com/projects/esp-idf/en/v5.0/esp32s3/get-started/index.html#installation][ESP-IDF]] properly configured on system.
|
|
#+BEGIN_SRC shell
|
|
. $YOUR_PATH_TO_ESP_IDF/export.sh
|
|
#+END_SRC
|
|
|
|
Set the target chip and configure the project. NOTE: Running menuconfig is not currently necessary for this project.
|
|
#+BEGIN_SRC shell
|
|
idf.py set-target esp32s3
|
|
idf.py menuconfig
|
|
#+END_SRC
|
|
|
|
Add the dependencies. They will install upon building the project the first time.
|
|
#+BEGIN_SRC shell
|
|
idf.py add-dependency "espressif/esp_lcd_ili9341>=1.0.2"
|
|
idf.py add-dependency "lvgl/lvgl>=8.3.0"
|
|
#+END_SRC
|
|
|
|
Building and flashing the project. Where $PORT is the boards serial port system address (e.g. /dev/ttyUSB0).
|
|
#+BEGIN_SRC shell
|
|
idf.py build
|
|
idf.py -p $PORT flash
|
|
idf.py -p $PORT monitor
|
|
#+END_SRC
|
|
|
|
Or do all of this in one go with:
|
|
#+BEGIN_SRC shell
|
|
idf.py -p $PORT flash monitor
|
|
#+END_SRC
