If you have read my blog at all you may be beginning to think I have a fetish for the MCP9808. Well, maybe a little, but for a good reason. If we look it’s data sheet we see the MCP9808 is a surprisingly complex device. Some of the features the data sheet lists: Accuracy: ±0.25 …
This blog post will demonstrate how to configure Jetbrains Idea (or similar product) to remotely debug Node js applications on an Intel Edison. Though I will use Edison for this post these instructions should work for remotely debugging most Linux targets running Node. I’m a big fan of using Node js to power my IoT …
Update November 4, 2015 With the release of mraa 8.1 there is now support for Node. 4.X. Upm 4.0 now allows the installation of upm modules via npm. I have updated this post to account for the new capabilities of these libraries. There is also the option of updating the libraries by using the XDK. …
Update October 12, 2015 MRAA 8.0 and UPM 4.0 have been released recently. These releases offer improvements in both stability and, in the case of UPM, an increase in number the sensors supported. I have updated this post to install the latest versions of this software. End Update. After recently receiving my Minnow Board Max (MBM) I found …
UPDATE October 6, 2015. The current version of UPM (4.0) includes this driver. However, UPM 4.0 requires MRAA 8.0. It is pretty simple to install both of these on your Edison. I have updated this guide to use the latest library. End Update. The SSD1306 is a very common display driver. There are tons of SSD1306 …
In a previous post I discussed using the LMSensors project programs to scan I2C buses on the Intel Edison. As I mentioned in that post, I only had luck scanning bus 1 on the Edison (which is only available on the mini breakout board). Generally, when using i2ctools to scan bus 6 on the Edison the …
Rotary Encoders are supported by the UPM library. There is already example code that can be leveraged when we want to use one. The code was created for the Grove Rotary Encoder but in reality we can use it for any rotary encoder we choose to implement. The Grove encoder would be a good choice if …
On my current project I have the requirement to monitor indoor air quality. What is of interest are the levels of Volatile Organic Compounds (VOCs) and CO2. There are specific thresholds that we are looking for that when exceeded should trigger an action. For VOCs it is when the concentration is greater that 0.9 ppm. …
One of the things I really like about the Intel Edison (and the Galileo) is that they can be run as little Linux computers. We can use a lot of tools that are available for Linux machines. One of those tools in particular is nodejs. Nodejs is a very powerful server side platform. It comes …
Edit October 24, 2015. The I2C tools project has split from lm-sensors and has gone mia recently. Some of the links I had provided stopped working. I have not been able to track down a good reference for all the tools as yet. When I do I will update this post to let you know. …
