Hello Erik

I thank you for your patience.

good day

Hi,

Directly it cannot handle MIPI DSI as there is not hardware peripheral built into the SoC.

However you can use another chip (co-processor, driver, bridge) to drive the display. For example, quick googling gave me this here:
SPI to MIPI DSI bridge

I want to note, that I have never used this and this is just an example, there are other solutions out there as well that might be better for your application.

Hello Erik

I'm sorry I did not understand you properly.

I asked you before if the Soc Nrf52832 can handle with midi DSI

Hi Eli,

You missunderstood me, I was saying that none of the both SoCs (nRF52840, nRF52832) has such support.
You are left with the two other options that I mentioned- other display or co-processor/driver for MIPI DSI.

Personally I have not worked with Adafruit Feather boards, however as far as I know they are using Nordic SoftDevice/BLE Stack and some parts of the SDK. Other than that most of the code base is developed and maintained by Adafruit team.

Hello Erik

Thanks for your response

You indicated that Soc Nrf5840 support MIDI DSI, can you refer me to the document?

With your permission Another question, when adafruit company is launching a new product link feahter Nrf52832 board and to get support in Arduino we install the BSP, Does Nordic provide the library?

Thanks

Hi Eli,

Unfortunately nRF52840, nor nrf52832 has on-chip hardware support for MIPI-DSI.

Your alternatives here would be to use different display that supports I2C or SPI (or Parallel) communication format
OR
You could use some co-processor / driver that supports MIPI DSI and control it though nRF52 SoC.
