Re: Engineer needed to build breakout boards - Old "AirPi" project

Hi Heater, They are in NEMA enclosures in the baking California sunshine. A few year back I had one outdoor PI system fail. Turned out not to be a PI problem but the SD card went on fire. Almost literally, the SD got hot and smoked when I got it back on the bench and powered it up. In general, the P...

Re: Engineer needed to build breakout boards - Old "AirPi" project

Our company also does turn-key manufacturing (we typically won't touch less than 500 unit lots), but your project will likely be more feasible if you contact a local university industry outreach program. This Pi foundation project already uses the BME280, and I can verify it is quite a reliable litt...

Re: Is Openscad ported to Raspbian Stretch?

There should be no missing .so binaries required outside the repository files (also, installing unverified binaries is considered a dangerous practice). In general, the qt4 support worked fine for me right out of the repo... not really sure what your friend did. Our group will be releasing a signed ...

Re: Camera module blocks access to second i2c bus on port5?

Camera accesses the I2C via a I2C driver on the GPU. This code is closed source, but the I2C driver on the GPU is a very well tested bit of code. Camera driver itself isn't so well tested - I'll be looking at that when time allows. It is rumoured a V4L interface is in the development path as well, ...

Re: Camera module blocks access to second i2c bus on port5?

Custom C program to enable io access with the i2c-0 kernel module character device (based on offset noted in this thread ). They can work when configured independently, but the camera seems to enter into a resource contention when the port 5 interface is enabled. For your situation, one could probe ...

Re: Raspbian- Octave - installing packages

@randomvibe There are actually two ways to do this: 1. Create a loadable Octave C++ binary user lib. Andy seems quite knowledgeable in this area, and can likely offer guidance on how to avoid common issues. 2. Create a C++ program and use liboctave resources similar to this process: You will need to...

@Andy, thanks for the comment... but I wouldn't answer if I hadn't tried it myself. Current repo for octave in wheezy is v3.6. And the octave "pkg" command uses the same compiler wrapper for custom octave C++ binary modules. Notably, randomvibe could create a custom module if the io permissions are ...

Re: PiCalc

Have you tried:

Code: Select all

sudo apt-get install tiemu 
Note octave is very easy to learn too, and is free to use.

Re: Raspbian- Octave - installing packages

Apt-get is the normal ideal way to handle the dependencies, but in this case there are packages for 3 different versions of octave with incompatibilities :shock: . Optionally, one could use the following to handle large dependency lists, and still use the up-to-date internal version matched octave p...

Re: Raspbian- Octave - installing packages

In general, if you install some packages like NaN or the Matlab export tools it can cause inconsistent behavior. Additionally, some forge packages are not compatible after v3.0.5.
