LCDIFv2: LCD Interface v2

Overview

The MCUXpresso SDK provides a peripheral driver for the LCD Interface v2(LCDIFv2)

The LCDIFv2 supports RGB mode (dot clock mode), it supports up to maximum 8 layers of alpha blending.

Shadow load

Shadow registers are used for LCDIFv2 layer configuration, when layer configurations are set, they are written to the shadow registers and do not take effect, after the function LCDIFV2_TriggerLayerShadowLoad is called, the new configuration are loaded to the active control registers at next vertical blank period. This mechanism ensures that all configurations are loaded at the same time.

Frame store

The LCDIFv2 supports saving the output frame data to memory, application can choose two mode:

In one shot mode, the store process stops after one frame store finished. In repeat mode, the LCDIFv2 continues storing the new frame to the same address, it does not stop storing until reset.

Typical use case

Refer to the driver examples codes located at <SDK_ROOT>/boards/<BOARD>/driver_examples/lcdifv2
