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 and ILI9341. This version is enhanced with addtional functions which are needed to support changes in hagl to retain backgrounds whe drawing text. (hagl_hal_get_pixel and get_fb.)
Usage
To use with an ESP-IDF project you include this HAL and the HAGL graphics library itself.
$ cd components
$ git submodule add git@github.com:tuupola/hagl_esp_mipi.git
$ git submodule add git@github.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.
$ make menuconfig
Default configs are provided for popular dev boards. For example to compile for M5Stack do something like the following:
$ cp components/hagl_esp_mipi/sdkconfig/m5stack.defaults sdkconfig.defaults
$ make menuconfig
For example usage see ESP GFX, ESP effects and Mandelbrot.
