LVGL provides a ready-to-use project for the `EK-RA8D1 <https://www.renesas.com/us/en/products/microcontrollers-microprocessors/ra-cortex-m-mcus/ek-ra8d1-evaluation-kit-ra8d1-mcu-group>`__ development board. Its main features from the HMI's point of view are:
|
||||
|
||||
- 480MHz, Arm Cortex®-M85 core
|
||||
- 2MB Code Flash, 1MB SRAM
|
||||
- MIPI DSI & Parallel Graphics Expansion Ports
|
||||
- 4.5 Inch backlit TFT display, 16.7M display colors
|
||||
- 480x854 pixels resolution
