Module i8080

Available on crate feature unstable only.

LCD - I8080/MOTO6800 Mode.

Overview

The LCD_CAM peripheral I8080 driver provides support for the I8080 format/timing. The driver mandates DMA (Direct Memory Access) for efficient data transfer.

Examples

MIPI-DSI Display

The following example shows how to send a command to a MIPI-DSI display over the I8080 protocol.

let tx_pins = TxEightBits::new(
    peripherals.GPIO9,
    peripherals.GPIO46,
    peripherals.GPIO3,
    peripherals.GPIO8,
    peripherals.GPIO18,
    peripherals.GPIO17,
    peripherals.GPIO16,
    peripherals.GPIO15,
);
let lcd_cam = LcdCam::new(peripherals.LCD_CAM);

let config = Config::default().with_frequency(Rate::from_mhz(20));

let mut i8080 = I8080::new(
    lcd_cam.lcd,
    peripherals.DMA_CH0,
    tx_pins,
    config,
)?
.with_ctrl_pins(peripherals.GPIO0, peripherals.GPIO47);

dma_buf.fill(&[0x55]);
let transfer = i8080.send(0x3Au8, 0, dma_buf)?; // RGB565
transfer.wait();
