Peripheral LCD[edit | edit source]
The LCD-TFT (liquid crystal display - thin film transistor) display controller provides a parallel digital RGB (red, green, blue) and control signals for horizontal, vertical synchronization, pixel clock and data enable as output to interface directly to a variety of LCD and TFT panels.
Description[edit | edit source]
The LCD-TFT display controller (LTDC) interface available on ETRA SOM is based on STM32MP1 SoC.
The LCD-TFT port supports the following standards and features:
- up to 24-bit RGB parallel pixel output; 8 bits-per-pixel (RGB888)
- 2 display layers with dedicated FIFOs (64x64-bit)
- color look-up table up to 256 color (256x24-bit) per layer
- flexible blending between two layers using alpha value
- programmable window position and size
- up to 4 programmable interrupt events
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
