dev board with DCMI and MIPI-DSI pins/connectors

[walterg]

Hello, 

I want to evaluate a solution using a SMT32 MCU with a TFT display (MIPI-DSI) and a camera input via DCMI.

With these requirements I've restricted the MCU list to these 6 families:

• F469/F479
• F769/F779
• L4R9/L4S9
• U599/U5A9
• U5F9/U5G9

if I am correct.

The issue I am facing is that I have not found a Nucleo or Discovery board that carries those MCU and the relevant MIPI-DSI + DCMI connectors/headers or just bare GPIO pins.

The only ones I have found are discovery boards, much more expensive, like the STM32L4R9I-EIAC Discovery board which prices 300 $. I would also accept, at this stage, a board with an already installed LCD display, as there are many Discovery boards, but the all lack (unless I misread the specs) the DCMI pins exposed.

Am I missing something obvious in the ST.COM dev kits specs or list?

Or does anybody know of some breakout boards that just expose the GPIO pins, and maybe a power connector (just like this one for example, it exposes all the GPIO pins of a Raspberry compute module, plus it has a jack for power). 

I need something cheap and quick to validate my overall architecture and connections, before designing the PCB and have it printed.

BTW I've seen something that could work if I change my specs to a LCD using parallel RGB and a camera, but this time round I'd like to stick to a fewer data lines.  

Thanks for any suggestion.

Bye

Hello @walterg and welcome to the Community 🙂,

The issue I am facing is that I have not found a Nucleo or Discovery board that carries those MCU and the relevant MIPI-DSI + DCMI connectors/headers or just bare GPIO pins.

The STM32H747I-DISCO Discovery kit t is a complete demonstration and development platform for the STMicroelectronics Arm® Cortex®-M7 and -M4 dual-core-based STM32H747XIH6 microcontroller.

The full range of hardware features available on the board helps users improve application development by an evaluation of all the peripherals (USB OTG2 HS, Ethernet, microSD™card, SAI Audio DAC stereo with audio jack input and output, MEMS digital microphone, SDRAM, Quad-SPI flash memory, DCMI connector, MIPI DSI® interface, and others).

Also, you can use STM32F769I-EVAL board.

Thank you.

Kaouthar.

Hello @KDJEM.1  ad thanks for your welcome.

Yes, I 've seen the 747 Disco, it's nice but I wanted to test lower end processors like the cortex M4 since I wanted to build something with the least power requirements and I figured the M4 is less power hungry than the M7, but maybe I'm wrong. 

The same goes for the769 eval board. Nice but maybe too much for my project. I just need to relay images vith a decent frame rate (15ps upwards) from the camera to a LCD with VGA like resolution, nothing much fancy,

On the other hand I could start this way and then test field on a custom PCB the power consumption. I will think about it a little more. 
Thanks for your reply!

Hello @walterg,

In addition to the STM32L4R9I EVAL Board, there is the STM32L4R9I-DISCO (32L4R9IDISCOVERY), which embeds a DSI Connector (with default round LCD display 1.2" of 390x390 pixels ) and also embeds a DCMI connector interface compatible with the CAM module STM32F4DIS-CAM.

Best Regards.

Hello @GET,

I was aware but I wanted a bigger display. One question that I have often is how are the display/boards connected to the main Discovery board. Now it seems a bit clearer.  

At the moment I've ordered (and just received, not yet opened) the  STM32H747I-DISCO and the B-CAMS-OMV (the STM32F4DIS-CAM does not seem available anymore), so I will check and then, maybe afterwards, I will try the STM32L4R9I-DISCO and see what kind of connector board I need to have to use my available displays (which by the way are Blanview from Ortustech).

So thanks, I will get back with some feedback after I manage to get a working prototype with what I have.

Thanks, I think for the moment your answer and @KDJEM.1 are enough!

Best regards
