Suggestion: Raspbian "SpiritRover" Distro
All: Given how much work there seems to be in making the simplified educational layers to: - i2c devices at 0x1c, 0x32, and 0x6b - SPI Arduino interface (/dev/ttyAMA0) - raspberry pi computer vision Wouldn't it make sense to take a clean build of Raspbian Stretch and put all the software and utiliti...

Re: Spirit Machine Vision Discussion
Hey all. I got OpenCV tag 3.4.0 running on Raspbian Stretch, accessible through python bindings for both Python 2.7 or Python 3.5.
See my blog post at for what I did.

Re: Spirit Machine Vision Discussion
Hey mgodiya, Maybe we can help Kevin out with some OpenCV stuff using the python3 interface... I think we can make it simple enough for 3rd graders to do basic functionality through the Python interface, and since it's based on OpenCV, if some whiz kid wants to "dive deep", OpenCV is prett...

Re: Code Arduino from Rasbian with Spirit.
I *think* that the Arduino can be programmed via SPI, which means that it's over the GPIO interface, not USB, so the loopback cable wouldn't be needed. In /dev, you can see /dev/ttyAMA0 ... which looks suspiciously like an AVR microcontroller serial interface. But... when I install the arduino IDE, ...

Re: How to.... interface the RPi with spirit board
Also, what frequency is the i2c bus running at? It seems to be higher than 100kHz based on what I'm seeing with pigpiod and piscope, which can only sample the gpio at 1 microsecond... I'm also seeing 20Hz activity on the I2C pins (2 and 3) on the RasPI...

Re: How to.... interface the RPi with spirit board
Does anyone have a list of what's available at what addresses on the i2c in addition to what was in the python test code above? A handy reference would be nice...

Re: Spirit Machine Vision Discussion
The second big requirement is that it can be made easy. All of these bits of software appear quite complex, but if I can understand it well enough and I can write some simple functions that are "user friendly for the masses" then it'll work. Computer vision isn't simple by its very nature...

Re: Spirit Machine Vision Discussion
Hello all! In the recent Kickstarter updates, we've been discussing various options for running the machine vision system on Spirit. I built the prototype using SimpleCV, which works, but it's certainly not ideal. Much better solutions exist but as I'm not much of a software guy, I'm hoping for som...
