Old school fire effect for ESP32 based boards. Based on Lode's classic fire tutorial. 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 git@github.com:tuupola/esp_fire.git --recursive
$ cd esp_fire
$ cp sdkconfig.m5stack sdkconfig
$ make -j8 flash
If you have some other board run menuconfig yourself.
$ git clone git@github.com:tuupola/esp_fire.git --recursive
$ cd esp_fire
$ make menuconfig
$ make -j8 flash
