Re: CortexM4F and Rasberrypi

Basically, I need to connect an Adafruit M0 Feather to my Raspberry Pi through SPI, since I am doing a project that consists of creating a LoRa network. Well I do know a bit about that as I have two LoRa feathers and one day want to connect them to Pi's. LoRa is a low rate RF comms so you should be...

Re: CortexM4F and Rasberrypi

I'm really sorry! I think my problem is very stupid and I don't want to bother everyone with that.
Not asking the question is stupid.
We still don't know what the question is?

That's a good point. Maybe the question was something to do with Ultibo. Hmm better off asking on the Ultibo forum then, more knowledgeable people there than me. I am still learning that too, I can fumble through someone else's working examples. My contribution's to Ultibo are mostly commenting and...

Re: What motion sensors suitable for drones, work with a Pi ?

Broadcom haven't fixed the problem with their I2C interface
What OS/Language are you using?
I gave up on i2c + Linux and now use Ultibo(baremetal), works fine.
Have not tried Ultibo for drones yet.

Re: Unity in Raspberry Pi 3 or other small computers?

Check on Unity's web pages. I thought I had seen something about Unity on Android and since most Androids run on ARM with OpenGLES , one day on Pi's? However the push now is Aarch64, ie 64bit Android and Raspbian is still only 32bit. Gentoo64 to Aarch64 with OpenGL runs well on Pi3's. I managed to g...

Re: CortexM4F and Rasberrypi

In the present case a subject line such as "Adafruit interfacing question for Gavinmc42" might suffice.
Well it might, except I make my own microcontroller and I/O boards and have not yet needed to do a Pi/Adafruit combo.
Better off asking on the Adafruit forum?

Re: Is there a complete webcam surveillance package.

MotionEye OS is smallish image size OS.
Pikrellcam is installed over Raspbian Lite so it take more work to get installed and running.

Both have large, active forum posts.
MotionEye OS is simpler, Pikrellcam has more features.

Re: TCS34725 RGB sensor

Can we get a number for yellow colour, like the Red, green and blue so we can plot a graph of it? No, any number would be a guess. Without having a yellow filter you cannot tell, a guess would be if you are measuring a small spot. Then you could make the assuming that you re measuring one yellow sp...

I find it quite amusing to suppose the purpose of a trade secret is to hide the fact that the product may infringe on multiple patents.

Patent Trolls?
Open it up so everyone can see how it works next thing you know lawyers are descending for a piece of the action.
Blah,blah com has that patent, doofdoof inc owns that patent etc, result = cease and desist orders = no more Pi's.

Re: Problem with Raspberry PI Zero in OTG/Slave USB mode (approx. 8% of modules fails to be detected as USB Ethernet gad

That sort of failure rate suggests it may be a software or timing issue.
Especially as USB host mode works.

Edge case example?
Returning hardware for things that can be fixed in software?
That will not find the issue and fix it.

Document the setup so others can try to get the same fault.

Re: So far - Thank you Raspberry Pi.

I use old second hand monitors, $15 for the last one a few weeks ago.
As long as the monitor has DVI digital or HDMI input it can be used.
For DVI all you need is a HDMI to DVI adapter or cable.
Even a TV will work.

In my experience, the only people who find Ada "painful" are those who like to hack stuff together without thought, like they do in C or C++ and then spend weeks in a debugger fixing the problems.

Digital Making is at the core of the RPF message, but it's not getting the billing that it should.

Once the address is a real one I then write it to the LCD. Remember to have a timeout loop in the start up in case the netw...

Please do something about "M2.5" standoffs market availability. (And perhaps try M3 holes in the next design...)
