I'm wondering if anyone has gotten a tft touchscreen to work with a Coral Dev Board? I have a Coral Dev Board Mini as well as several 2.4 and 2.8 inch Adafruit mini-hat touch screens and would love to know if anyone has gotten any of the Adafruit TFTs (or ANY TFT display) to work with a coral dev board. I've tried and have basically gotten nowhere. Adafruit website says it supports the Coral boards through CircuitPython, Blinka, etc. and I've followed the install instructions with no luck getting a TFT to work. Any success story or help much appreciated.
Thanks,

The DSI interface is not currently enabled. You can follow this patch https://coral.googlesource.com/linux-imx/+/d0a15d32e9a56f67954eb6b9d19b895901787319 to understand how to enable a display panel. This patch is for reference only as it is applicable to Tianma display that has been tested with the Coral dev board and not the Dev board Mini.

In the official datasheet for the Google Coral USB accelerator (https://coral.ai/docs/accelerator/datasheet/), they mention two LED behaviors - LED on (solid) and LED pulse (breathe).
However, apparently, there are more LED modes.
For example:
https://github.com/google-coral/edgetpu/issues/675
https://github.com/google-coral/edgetpu/issues/476
So, does someone know and have a complete list of these different blinking modes with their meaning?
Have you ever tried to connect a touchscreen display to the board? Is there a model that would be compatible? What solutions are there?
Thank you!
As per a response from Coral team, they have only tested the Tianma TL060FVMS07-00 model, it is a touchscreen display.
Here is the full patch they made to support the Tianma display: https://coral.googlesource.com/linux-imx/+/d0a15d32e9a56f67954eb6b9d19b895901787319
I'd like to reduce idle power consumption on the Google Coral Dev Board anyway I can by turning off USB/ethernet/HDMI/LEDs etc. I'm struggling to find much information for how to do this. I've searched through i.MX8M documentation, and have tried similar approaches like you would do with a Raspberry Pi but obviously these aren't the same and I've struggled to find corresponding locations in /sys/.
Can anyone recommend documentation or give advice on how to turn off these components from the terminal?
I'm not sure if those parts can be turn off, but if power is what concerns you, you can try turning on this option:
CONFIG_IMX8MQ_PHANBELL_POWERSAVE
in the kernel's defconfig.
You can follow this answer to see how that is done :)
my current situation is that I need to run a simulation on htc vive using ROS. For now I have connected ROS and v-rep on virtual box, ubuntu. I have connected htc vive on windows and setted it up with steam vr. I would like to set it up so that I could stream simulation through virtual box using ROS on htc vive which is on windows.
I know that I need to write a script for that, ROS using TCP so I can connect vive which is on windows, but I am also interested if someone can explain me more about that, or someone has better solution for running a simulation on vive using ROS since I haven't done something like that before? Or is it simpler to use oculus rift with dual boot and put ROS there?
as no one has answered you might guess there is a bigger gap....you would have to visualize your ros worl. Also you need a two way comminication...thought you have to study some more technolgies and come with a problem
I want to make my own ios app with homekit, which should control arduino, i have studied about homekit and i have doubt that whether it is possible to integrate arduino or raspberry PI with home kit or not ? any useful links ?
I'm not sure about the arduino, the crypto behind the protocol is fairly complex and I'm not sure the processor could handle it well. I can find any sample projects out there either, but the Rasbery pi is another story. Since the Pi can run node, there is a node implementation of hap on github: https://github.com/KhaosT/HAP-NodeJS
I haven't used it, but it's fairly well documented. I doubt there are any tutorials available, I think these are fairly fringe projects at the moment, so you're going to have to get your hands dirty. Good luck.
