I had trouble getting the time to work on my Arch GPRS V2 in the last post, which is a shame because it would be incredibly useful. Fortunately, I stumbled across a lead which I was able to follow.
Since I had gotten serial communication working to my Arch board, and with it basic debugging, I decided the next step was to get measurements from the Grove humidity sensor.
As development for this module occurs in a browser, rather than an IDE with the typical debugging features, the best way to troubleshoot is to print messages over a serial port that can be read by a laptop.
After successfully connecting WiFi to my RPi, I had something which was headless and portable (except of course, for power). The next step to turn it into a minimally interactive information panel was to add the display. The timing is a bit uncanny because Raspberry Pi just released a 7 inch touchscreen, but I’m going … More Adding a display panel to the RPi
I set up WiFi on my Pi with the module I recently bought, so that I can move it away from my router.
This post is mostly just a repository for all the resources required for setting up GUI development on a Raspberry Pi.
The ARCH GPRS V2 can be programmed using the mbed platform. I actually had a bit of trouble programming it so I’ll share my process here.
My plan to make a minimally interactive bedside display will require a few components to construct the system.
I hate technology.
As mentioned in the introductory post, this project will, at the very least, require the selection of a controller, a cellular device to send and receive SMS messages, and a humidity sensor.
