MIPI DCS HAL for HAGL Graphics Library
HAL for HAGL graphics library for display drivers supporting the MIPI Display Command Set. This covers most displays currently used by hobbyists. Tested with ST7735S, ST7789V, ST7789V2, ILI9341, ILI9342C and ILI9163. Works with both ESP32 and ESP32-S2.
To use with an ESP-IDF project you include this HAL and the HAGL graphics library itself. If you are using CMake based build the HAL must be in folder named
$ cd components $ git submodule add firstname.lastname@example.org:tuupola/hagl_esp_mipi.git hagl_hal $ git submodule add email@example.com:tuupola/hagl.git
You can alter display behaviour via
menuconfig. If you choose to use back buffer all drawing operations will be fast. Downside is that back buffer requires lot of memory. To reduce flickering you can also choose to lock back buffer while flushing. Locking will slow down draw operations though.
$ idf.py menuconfig
You can also use the older GNU Make based build system.
$ make menuconfig
Default configs are provided for popular dev boards. For example to compile for M5Stack do something like the following:
$ cp components/hagl_hal/sdkconfig/m5stack.defaults sdkconfig.defaults $ idf.py menuconfig
