Primary LanguageC

LittlevGL ported boards and microcontrollers

This repository contains projects where LittlevGL is configures for a development board or microcontroller.

Contributing is very welcome! Plaase, share with others if you used LittlevGL with a new board or MCU.

Usage

  1. Clone the repository somewhere: git clone https://github.com/littlevgl/lv_boards.git
  2. Step into the repository: cd lv_boards
  3. Initalize the submodules: git submodule update --init
  4. Copy/Paste a project where you want to use it (e.g. IDE workspace)

Porojects

arduino_library

LittlevGL as an Arduino library. Copy arduino_library/littelvgl to your library folder Check the lvgl_test sketch to see the proting and usage

esp32_ili9431

Driving an 320x240 TFT with ILI9432 controller via SPI using ESP32. The project is craeted in Eclipse using ESP IDF. (Getting started guide here) To link LittlevGL and lv_examples with ESP-IDF you need to add component.mk files to each directory. Rename lvgl_component.mk and lv_example_component.mk to component.mk and copy to the lvgl and lv_examples directories.

stm32f429_discovery_no_os

Cheap development board with 240x320 TFT, Resistive touch pad, 180 MHz MCU with 256kB RAM + 64 MBit SDRAM and GPU. The CubeMX drivers are used to initilaize the peripheries. In hal_stm_lvgl/tft/tft.h you can enable/disable external frame buffer placement and GPU usage.

stm32f469_discovery_no_os

STM development board with 800x480 TFT and MIPI DSI interface, capacitive touch screen, 180 MHz MCU with 324kB RAM + 128 MBit SDRAM and GPU. The CubeMX drivers are used to initilaize the peripheries. In hal_stm_lvgl/tft/tft.h you can enable/disable external frame buffer placement and GPU usage.

stm32f746_discovery_no_os

STM development board with 480x272 TFT, Capacitive touch pad, 216 MHz MCU with 320kB RAM + 64 MBit SDRAM and GPU. The CubeMX drivers are used to initilaize the peripheries. Solution uses frame buffer placed in the external SRAM memory. GPU is configurable over USE_LV_GPU define. To compile example go to Release directory and run make.

pic32mx_r61581_no_os

A custom PIC32MX695H based board drives a 480x320 display with R61581 display controller via software parallel port. The MCU has 512kB flash, 128 kB RAM and tuns at 80 MHz. It able to applay font anti-aliasing and even screen sized animations. Touch pad driver is not added yet.

pic32mx_ssd1963_no_os

A custom PIC32MX695H based board drives a 800x480 display with SSD1963 display controller via software parallel port. Still work in progrss.

linux_frame_buffer

Directly use Linux fame buffer (e.g. /dev/fb0) as frame buffer. Demonstrates the usage winth embedded Linux systems. The project is created in Eclipse CDT. Learn more here: LittlevGL Blog Post
