LCD controller capable of driving a MIPI-DSI display?

Hi support,

I was wondering if it was possible to connect to a 1 channel MIPI DSI display using the LCD controller in the DA1469x family of devices? It's not mentioned in the datasheet, but there are a couple of mysterious registers in table 157:

0x30030028
LCDC_DBIB_CFG_REG
MIPI Config Register

0x300300E8
LCDC_DBIB_CMD_REG
MIPI DBIB Command Register

 

 

I don't have the slightest clue what these might do, but I was just curious if it was even possible to drive such a high speed signal with one of the DA1469x devices. Also, what does DBIB stand for? I couldn't find it anywhere.

Thanks!

Hi coltonrb,

Hi coltonrb,

The DA1469x supports MIPI DBI (Display Bus Interface) display. The MIPI DSI display is not supported.

MIPI DBI specification declares a variety of parallel and serial interfaces. The LCD controller supports two serial interfaces in write only mode:

  • DBI-C option 1: DCX signal is a bit preceding each byte (9bit mode). This mode uses 3 wires and in software is referred as SPI3 mode.
  • DBI-C option 3: DCX signal is an extra line. This mode uses 4 wires and in software is referred as SPI4 mode.

Thanks, PM_Dialog
