HAGL graphics library speed tests for ESP32 based boards. See the accompanying blog post. Ready made config files for M5Stack, TTGO T-Display and TGO T4 V13. For example to compile and flash for M5Stack run the following.
$ git clone https://github.com/tuupola/esp_gfx.git --recursive
$ cd esp_gfx
$ cp sdkconfig.m5stack sdkconfig
$ make -j8 flash
If you have some other board or display run menuconfig yourself.
$ git clone https://github.com/tuupola/esp_gfx.git --recursive
$ cd esp_gfx
$ make menuconfig
$ make -j8 flash
Or if you are using the new build system.
$ git clone https://github.com/tuupola/esp_gfx.git --recursive
$ cd esp_gfx
$ idf.py menuconfigs
$ idf.py build flash
Below testing was done with the TTGO T-Display. Buffered refresh rate was set to 33 frames per second. Number represents operations per seconsd ie. bigger number is better.
