Re: Expandable baseboard (slot system) for CM3

Yes, both of them can be mounted (for sure).
CM3 slot is higher; basically that's how SO-DIMMs on some mainboards are arranged

LVDS4PI is a DIY solution which I've developed/build for working with LVDS displays.

Re: 8.4 inch TFT LCD touch panel model G084SN02 interface

From your explanation the touch seems can be 4-wire resistive; without posting details nobody will know (at least I will not google4you). If that's the case https://www.adafruit.com/product/1580 should do. Regarding LVDS you need to build/buy an adapter board (which either converts DPI or HDMI to LV...

Re: Expandable baseboard (slot system) for CM3

Very nice! How can you insert an expansion card if CM3 slot is populated? Are there enough space? And what is the main goal of this board? simply by removing the CM3. One goal is to see if it can be done that way,if the design is o.k. for DSI and CSI signals and I2S. Main goal for me is having sing...

Re: 3 pcs of Atmega328 connected to 1 raspberry pi 3

Answer to your question: As stated already, you should use I2C to communicate with your atmega328 MCUs. Raspberry...

Re: Compute module soldered to the main PCB

Hi, Has anyone made experience with soldering the Compute Module directly to a PCB? I know that it is intended to fit the device in a DDR2 SODIMM socket. But if a removal of the Compute Module is not planned, the socked could be saved. So, are there arguments against soldering? How do you want to s...

Even if no of pins is the same the pin functions are different most of the time. Only exeption I know of is 15in 4:...

Re: LCD screen that i disasembled from a tabled

Based on info from Panelook - http://www.panelook.com/modeldetail.php?id=19717 - the display has single channel LVDS interface. You need some glue logic if you want to connect it to your Pi. Easiest solution is a suitable AD-board which connects to HDMI, more advanced is DIY (search the forum for LV...

Re: Stream display output from not-network-able with RBP3

Will your PC allow you to install any software? Why can't you simply add a USB-to-ethernet adapter?
Maybe camera 'capturing' and streaming would be best it system is that 'secure'

Depands on your device (pulse oximeter). So you should check the protocol (device class) first to see if there's a driver already or if you need to program it by yourself.

Re: Salvage LCD from portable DVD Pi3

How do you know your TFT has a LVDS interface without having the spec?

Most likely it's RGB (DPI; 18- or 24-bit) ... Anyhow, the timing needs to be correct for both interface types. So you will either need the spec or tons of time to figure it out

Re: Salvage LCD from portable DVD Pi3

What you can do: 1.) you need to figure out which display module you have (manufacturer, part number) 2.) you need to be able to get Hands on the display data sheet 3.) if it has a 18- or 24-bit RGB Interface you can try to source an FPC adapter (as an example only: https://www.adafruit.com/product/...

For example, lcd_rotate=2 will compensate for an upside down display. Such a feature is available...
