@ -40,9 +40,8 @@ LittlevGL provides everything you need to create a Graphical User Interface (GUI
Basically, every modern controller - which is able to drive a display - is suitable to run LittlevGL. The minimal requirements:
- **16, 32 or 64-bit** microcontroller or processor
- **> 16 MHz** clock speed
- **> 8 kB RAM for static data** and **> 2 KB RAM for dynamic data** (graphical objects)
- **> 64 kB flash** program memory
- **Optionally ~1/10 screen sized memory** for buffered drawing (on 240 × 320, 16-bit colors it's 15 kB)
- **> 16 kB RAM** for static data, dynamic data (heap), stack and display buffer (> 32 kB is recommended)
- **> 64 kB flash** program memory (> 180 kB is recommended)
Just to mention some **platforms**:
- STM32F1, STM32F3, [STM32F4](https://blog.littlevgl.com/2017-07-15/stm32f429_disco_port), [STM32F7](https://github.com/littlevgl/stm32f746_disco_no_os_sw4stm32)
