Re: Waveshare 10.1 B LCD not proper working (some colors inverted)

Hi,
use a good quality HDMI cable. If this is also not working I would recomend to get in touch with your LCD vendor and claim warranty/replacment.

Just one more question: this Screen seems to run from 5V only (via USB Interface). Is your power supply sufficient (spec says 2.5A)?

Re: 40pin LVDS Converter Of Highest Quality?

It has gold contacts so it must have a good quality. Sorry, just kidding! Don't know what you call good quality or best, it does the job it was developed for, so that's enough. There is a tread in the forum on custom HDMI modes ( https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=24679)

Re: Compute IO Board Cost

CMIO is intended for development only as people interrested in using the Compute Module tend to develop their custom I/O(base)board with the size and functions their commercial application needs.

Have you tested it with another HDMI source (PC i.e.)?

If it is working there I would try a custom HDMI mode

Re: 40pin LVDS Converter Of Highest Quality?

Chalkboard will do the job. Custom HDMI mode will be required most likely.
Display is single channel LVDS.

Re: Waveshare 10.1 B LCD not proper working (some colors inverted)

Hi,

I would suggest to connect your Screen to a PC (or any other HDMI source) to see if it's working correctly.
Then, start with an unmodified config.txt (fresh installed Raspbian i.e.) and add

Code: Select all

hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_mode=28
hdmi_drive=2
Let us know your result.

either use together with https://www.adafruit.com/product/2454 (making use of RPI DPI interface; consumes most GPIO) or https://www.adafruit.com/product/2218 for HDMI

In case of HDMI https://www.adafruit.com/product/2232 is cheaper and less parts

Re: 45 pin lvds to HDMI

Display spec says RGB interface; so it should be DPI and not LVDS.
Search the forum for DPI, as it ja possible to connect such displays directly.
Or use a TFP401 based adapter.

Those 0-Ohm resistors are for current measuring; not needed on your own board (unless you want to have possibility to check current draw on a particular voltage rail)

Re: Any list of all available boards for CM? Any with SPI?

Why not use the CMIO (https://www.raspberrypi.org/products/compute-module-io-board-v3/) As the compute module exposes all pins on the SODIMM connector you can also think about 'hacking' another baseboard (i.e. RPI media stick from WDlabs; https://www.wdc.com/de-de/products/wdlabs/media-stick-for-ras...

Cannot see the bonet mentioning I2C. Thing is the Ali display does clearly say "SPI" written on it. Just the pins are strange.

Re: Wiring Adafruit Eyes Bonet + China Displays | SPI/I2C?

doesn't the bonnet Support I2C and SPI? As your Display has documentation for I2C Interface you should start with this.
In Addition you Need to ask the seller for the documentation. How should anyone answer your question without a spec?

You should opt for the TFT https://www.adafruit.com/product/2088 as it's cheaper than the OLED. The bonnet https://www.adafruit.com/product/3356 simplifies wiring but can also be omitted if you want to do it cheap.

Re: The best (fastest) bus for Pi (zero W/3)

You should mention which display size/resolution you're looking for! For small sizes SPI might be enough, for larger sizes/resolutions you should use DPI (https://www.raspberrypi.org/documentation/hardware/raspberrypi/dpi/README.md). Note: DPI consumes nearly every GPIO of your RPi. Two displays on ...
