Re: Multiple Frame buffer beta testers wanted

He guys! First of all a big THANK YOU for this! Can't wait to test the new features on my CM3 hardware. How many display can be connected to a RPi4? It has DSI + 2x HDMI + DPI I assume DSI + DPI is still a no go or are the hardware restrictions gone now? Speaking of an RPi 4 is it possible now to us...

Re: 2k Portrait Mode HDMI Display 1440p (1440x2560) how to rotate into Landscape?

What happens if you change

Code: Select all

display_rotate=0
framebuffer_width=1440
framebuffer_height=2560
to

Code: Select all

display_hdmi_rotate=1
framebuffer_width=2560

Re: Using a Pi zero with emmc

OP has pictured a Pi Zero on 'his device' ... So he may assume he can order it at USD5 in volumes. But only Zero WH can be purchased in volumes, hence total cost of ownership (Pi 0 WH + eMMC) becomes different (some example prices for 32GB eMMC https://www2.mouser.com/ProductDetail/Toshiba-Memory/TH...

Sorry, but I'm confused now! You have an adapter for eMMC which has shape/interface as a uSD card? So you want to stick this into the uSD card socket of a Pi Zero? If yes for both this should work. People here - me included - were expecting that you want to add the component (eMMC) itself to your ba...

How do you want to add an eMMC to a Pi Zero when the required signals are not available?

As said already either use a Compute Module or live with uSD.

Looks like a problem with your screen and not the RPi.
So you're better off asking Waveshare or your supplier for support/replacement

Re: Raspberry Zero USB connection Lost and don't detected again in Linux OS As USB Devices

You are using a display with touch with the touch connected to USB port; is this correct understanding?

A Pi Zero can either be Host or Device, means with the touch connected/configured you are no longer able to make use of USB gadget mode.

No of pins gives not information to anybody, so it's meaningless to mention. You need ti start with your displays data sheet. Search the web for it. In case you can find it look for the interface type(s) available. Most likely it's SPI and/or DPI. In that case you might be able to connect it. But .....

Your boot partition is too small. I've used 'gparted' to reduce the size of the second partition and then increased the first of the first one.

HDMI problem? There is no problem! There is only one display supported atm.
As said, some work is done to allow for two displays, but it's not released yet.

Until this has happened you can either use HDMI or DSI display.

Re: Can the Raspberry Pi GPIO Pins be expanded?

For PWM output you should have a look at I2C PWM controllers.
For analog inputs you could use I2C ADC (i.e. ADS124S06IRHBT from TI which has 6 channels)
