Does emWin and LCDC support SPI-4 LCD?

Hi Dialog Team,

SDK10.0.10.118

I am using emWin sample to as a base and adding a new SPI-4wire AMOLED display module and a I2C touch support,

//www.xmece.com/products/connectivity/bluetooth-low-energy/smartbond-reference-designs/emwin

By tracing lcdc adapter, and sample of DT280QV10CT, it seems even example are SPI LCD, I saw the phy type of DT280QV10CT is HW_LCDC_PHY_MIPI_SPI4.

However init command are all still LCDC_MIPI_CMD(xx), does it mean LCDC_MIPI_CMD are working with SPI interface display module?

I am a little cofused with LCDC_MIPI_CMD, becasue the real interface for those display should be SPI, right?

Are we able to use LCDC_MIPI_CMD directly or we need to implement a LCDC_SPI_CMD to suuport SPI interface display module? Thank you in advance.

Hi Dialog team,

Why it used LCDC_MIPI_CMD, even interface is SPI4?

Hi jerryjuan,

Hi jerryjuan,

The official terminology for the SPI3/4 is MIPI Type-C. The MIPI is referred to all the serial interfaces. Please check ad_lcdc_driver_conf_t – the HW is configured as HW_LCDC_PHY_MIPI_SPI4 . The SDK supports different macros for sending data and commands, that is, LCDC_MIPI_CMD , LCDC_MIPI_DATA (located in ad_lcdc.h file). From the LLD point of view, check the hw_lcdc_mipi_cmd API (located in hw_lcdc.h).

Thanks, PM_Dialog
