MIPI DSI has been widely adopted. It is ubiquitous in smartphones and also being used in tablets, laptops and laptop/tablet hybrids. It is also being implemented by the automotive industry for dashboard displays and in-car infotainment systems, and used in wearables, IoT and virtual/augmented reality applications.

MIPI DSI operates on the MIPI D-PHY physical layer. It uses a command set defined in the MIPI Display Command Set (MIPI DCS). It also incorporates the Display Stream Compression (DSC) Standard from the Video Electronics Standards Association (VESA). Overall, the feature set of MIPI DSI is quite similar to that of the more recent MIPI DSI-2℠ specification, which offers support for both MIPI D-PHY℠ and MIPI C-PHY℠.

First, you need to check whether this display has On-cell or In-cell touch panel, if has, it only needs to add a cover glass on it. If not, it needs an external touch panel.

Because the shape of the cover glass depends on the design of the clients, to avoid infringement of appearance, most of the developers need different customized touch panels.

Display Serial Interface (DSI*) specifies the interface between a host processor and peripherals such as a display module. DSI is a high speed and high performance serial interface that offers efficient and low power connectivity between the processor and the display module.One link x8 data lanes or two links each with x4 lanes support.

The MIPI® Alliance offers two specifications for implementing mobile displays: the Display Serial Interface (DSI℠) and the Display Serial Interface 2 (DSI-2℠). These specifications enable the creation of very high resolution displays while using exceptionally power-efficient physical layers. For this reason, MIPI DSI and DSI-2 based displays have become the devices of choice for high-end smart phone manufacturers, and they are also increasingly used in non-mobile applications such as infotainment systems or wearables.

Modern DSI and DSI-2 implementations include advanced innovations, such as compression, spread-spectrum clocking, and Bus Turnaround (BTA), which give rise to substantial design and validation challenges. Fortunately, Introspect Technology has created the most complete suite of test tools for display driver integrated circuits (DDICs) as well as completely assembled display panels, ranging from protocol exercising and analysis to high-volume production testing and system-level emulation.

The Synopsys MIPI® DSI/DSI-2 Host and Device Controller IP solutions are fully verified and configurable controllers that implement all the protocol functions defined in the latest MIPI DSI and DSI-2 specifications.

Synopsys MIPI DSI/DSI-2 Host and Device Controllers and C-PHY/D-PHY, and D-PHY IP provide a complete display interface IP solution that enables designers to lower their risk and cost of integrating the MIPI DSI and DSI-2 interfaces into application processors, display bridge integrated circuits (ICs) and multimedia coprocessors, while improving time-to-market.Synopsys Demonstrates MIPI Camera and Display Prototyping System

Synopsys demonstrates proven system-level interoperability utilizing Synopsys" DesignWare MIPI CSI-2 and DSI host controller as well as the DesignWare MIPI D-PHY IP solution.

Every STM32 that features a MIPI DSI host has a pair of differential clock lines (CLK0_P and CLK0_N). This clock pair can put out a maximum clock rate of 500 MHz, which results in the data lanes (DATA0 and DATA1 pairs) shifting out data at 1 Gbps each.

The MIPI Alliance specifications do not specify a maximum resolution or frame rate. It is up to you to negotiate and decide that with the display attached to the DSI host.

Also, because control traffic is also carried by the MIPI DSI interface itself, you have to make sure that there is no significant control traffic interrupting the graphic data stream. If there is, the display benefits from having a frame buffer. Ultimately, depending on the timing parameters specified in the LCD display datasheet, the maximum resolution and frame rate can be determined and it strongly depends on the display controller.

Note that the STM32 DSI host is capable of halting transmission, i.e. if your display has a frame buffer, you can save some power by deactivating constant streaming of the video buffer through the DSI host. If you are interfacing to an non-framebuffer type display, it could be a good idea to allocate the display data into external SDRAM connected to the STM32 and let the LTDC stream it out to the LCD via the MIPI DSI host interface.

Started a new project at work. We have to interface a 3.5 inch MIPI DSI TFT LCD to a Raspberry Pi (RPi) Compute Module 4 (CM4). The specific display is: https://focuslcds.com/product/3-5-tft-d ... b-mw420-n/

I have programmed microcontrollers to drive I2C, SPI, and parallel interface LCDs with 8 to 24bpp, easy to do. I have not programmed a computer running Linux to drive a display. So I don"t even know what questions to ask, so sorry if this info has been repeated before.

Is there any post or documentation anyone can point me to to get started? I can write the C code, the LCD supplier has a sample of initialization code, and I have written simple Linux scripts on the Pi. I just need to know the steps I need to take so I can break it down in to smaller chunks.

Have a look at https://github.com/raspberrypi/linux/bl ... verlay.dts and/or https://github.com/raspberrypi/linux/bl ... verlay.dts to get an idea what MIPi driver looks like.

From those it seems to look like 6by9 was adding ili9806e DSI support to the kernel. Does preparing for upstream mean that it might get included in to the kernel?

I"m no expert at MIPI DSI so yes this will be difficult. I"m an Embedded Engineer, I work with microcontrollers and interfacing them to various external peripherals including TFT LCDs. I"ve done USB and Wi-Fi bootloaders and those look easy compared to DSI.

It should be possible to extend it for other panels with alternate init sequences, but it won"t be merged until someone has taken it and confirmed that it works.

I did look at you ili9806e code for using SPI: https://github.com/6by9/linux/blob/rpi- ... ili9806e.c. I already know what I need to change there for using the controller in DSI mode so I thought I could start there. What would replace the SPI specific code? I know this is basic but does the Pi send commands to the display through DSI?

He sold management on the LCD I linked. I have found several hundreds of these displays, though I am told we should have 1000 of them. It was a planned production run, but circumstances have delayed it.

When looking for support you should keep in mind that people will struggle to support without having the display HW on hands (only a few have access to DSI analyzers ...), as one needs to see sometimes what is happening on the screen

My original question was what order do I start the development and were there any online resources I missed. You provided good information and a few links which is what I was asking to know, thank you. I have no other engineers to discuss this with and no MIPI consultants near by to "consult" with on the project. So any information is appreciated. Without the HW on hand I know others cannot assist. I am not asking for anyone to develop the project.

6by9 pointed me to his ili9806e SPI driver work, plus I have basic initialization code for the display. I"ve written most of the missing driver functionality. Once it can compile and the Pi attempts to run the display, then I will look into getting a MIPI DSI analyzer (Teledyne LeCroy or Keysight seem to be the major brands). I know they are expensive, but since I am going to be doing more projects with MIPI DSI it will be useful/required.

sure, you can, but as the official display is not a DSI - it is using a MIPI DSI to RGB chip - there are better resources which you"ve been pointed to already

The SPI driver is probably a dead end, at least initially. Get it working as a standalone DSI driver, and once working look at combining SPI config for DPI, and DSI into the one driver.
