| | | | | We need to be able to draw pixels onto the LCD screen of the ODROID-GO. Getting colors onto the screen will be more complicated than reading the state of the input buttons because the LCD actually has brains. The screen is driven by an ILI9341 which is a (very popular) "TFT LCD Single Chip Driver". In other words, we communicate with the ILI9341 which then responds to our commands to actually control the pixels on an LCD. | |

| | | | | [AI summary] The article discusses the author's experience of running Lean, a pure functional programming language, on an ESP32 microcontroller for a project involving LED control. Despite Lean's purity, the author utilized its monadic features to handle impure operations like GPIO manipulation and delays. The project involved significant optimizations, including custom bit-banging for the WS2812 LED protocol and reducing code size through various techniques. The author also outlines future directions for the project, including potential improvements in compilation, hardware support, and further optimizations. | |
