Re: What would be the next step up from CM3?

Maybe you should draw a sketch block diagram of the unit you want to develop. This is the Raspberry Pi forum, so - most likely - there are only limited number/no people here which design their own cameras. So you may need to ask camera suppliers for support. Anyhow, it doesn't matter how the camera ...

Re: Horizontal White Line on DPI Display of Raspberry

No spec = same as using crystall ball
As my crystall ball is under repair atm no answer possible for me
Good luck!
Anyhow: use hdmi_timing as this allows you to adjust correct timing.

Re: Horizontal White Line on DPI Display of Raspberry

As you've build some Adapter board let's me assume you have the full data sheet of the display on hands. You should get rid of hdmi_cvt=1024 600 60 6 0 0 0 and use correct timing (all details available from the Display data sheet) instead hdmi_timings=<h_active_pixels> <h_sync_polarity> <h_front_por...

Re: CM3 using DPI, I2C and SPI

DPI uses GPIO 0 (Zero) to 27 for 24-bit Color (GPIO0=clock Signal, GPIO1=DE 'Data Enable'). You want to use display in 18-bit color (mode5) so your DPI is on GPIO0-21. You can configure your GPIO either by device tree or via overlays. I2C0 is also available on GPIO28/29 = ALT0 or GPIO44/45 = ALT1 (r...

Re: LVDS add-on for Raspberry models with 40pin GPIO

Hi FUNcation, let's say your chances might be 50:50. Depends on your display timing and how sensitive the LVDS receiver is in regards of impedance mismatch. And, as timings for both display will be the same, only works with two identical displays (in case it works at all). Speaking of timing: what r...

If yes, how to configure the timings in case custom timings are required for both, HDMI and DPI?

As the screen used in Manga Screen 2 was developed for mobile phones you will have small current consumption for such a unit--> small battery size

As you're thinking about using 4-lane DSI let's me assume your HDMI is not in use, right? If that's the case, why not think about adding i.e. a TC358870XBG to your baseboard? This device is a Ultra HD to DSI bridge, which can convert your HDMI to MIPI DSI. As the GPU firmware is closed source you - ...
