For developing LVGL for Linux with or without Wayland on MA35D1 using resistive or capacitive touchscreens, please contact Nuvoton sales representative.
https://github.com/OpenNuvoton/lv_port_n9h30_freertos
https://github.com/OpenNuvoton/lv_port_n9h20
For capacitive touchscreen, LVGL uses the evdev driver to talk to touch panel. However, it is still possible to use the deprecated repository https://github.com/symfund/lv_port_linux_frame_buffer.git
For resistive and capacitive touchscreens, use this repository lv-port-ma35d1 instead.
To get driver implementation for the resistive touchscreen, execute the command
git submodule update --init --recursive --remote
Compiling LVGL with tslib backend for resistive touchscreen through the internal toolchain generated by buildroot
-
Add GCC cross toolchain path into the environment variable PATH
$ export PATH=${BR2_DIR}/output/host/usr/bin:$PATHwhere BR2_DIR denotes the path to the directory of buildroot.
-
Launch the make command to compile LVGL
$ make CC=aarch64-nuvoton-linux-gnu-gcc LDFLAGS="-lts $LDFLAGS" -
To deploy the LVGL demo, copy the out executable binary file 'demo' to target device.
