So we’ve finally got our second semester project briefs and it has been declared that we need to build a half duplex one direction communication system! Obviously, as its a project given by the university, it can’t be as easy as sending USART down a cable and receiving it, requiring pretty much no effort… at […]
4×4 Font Well! With the advent of multiple new LCDs to test out, I decided to challenge myself to designing a 4×4 font, a pretty grim task if I’m honest. A 4×4 font with good byte packing could store the whole font set from character 32 to character 127 in 190 bytes. Note that for […]
Wahooooo! Exams are over, term starts next week and I’m free other than a few nights out with me chums over the next few days. In the meantime, today brought the arrival of my first ever DSO (Hantek DSO5072P) and a new LCD (the other LCD came a couple of days back but that comes […]
Upon my return to Nottingham, I’ve been able to go down to the local RS counter and order new parts! Those new parts were the final little nuggets required for my current smart watch – ESD protection diodes and a micro SD holder! New arrivals! I’ve been waiting all Christmas to get these parts so […]
Well, starting with the updates first! As some of you may know, I’m at university, well through the first few weeks now. All seems well so far! None the less, university work renders me less able to post as often as I’d like to, or at least until the load relaxes a little (never i […]
Well! Its been a long time since I’ve actually blogged as I’ve been so busy! I’m now back at university (with 25 hours of contact time/week), along with vice president’ing UoN ShockSoc (https://twitter.com/Shock_Soc) and being the general secretary of BladeSoc (https://twitter.com/UoNBladeSoc), leaves little time for me to do much else! I have however been asked […]
As ever, the massive wealth of information on the internet and a bit of ingenuity of mine has lead to some improvements to my test application! Not only are all sentences sent from the module, received and stored in their corresponding buffers, I’ve written a few functions to parse some of the useful sentenced, to […]
Well! On another of my eBay whims, I decided to get a GPS receiver module. They’re normally relatively cheap (<£10 from the far lands! http://goo.gl/DGdbl0 – Link will expire!) and are surprisingly easy to use. I’d found a fair few Arduino versions but couldn’t really find anything on how they’re interfaced. My module literally has 4 […]
Well today has been productive! Here, I’m using my cheapo MAX7219 LED screen (cheaply available off my favourite website eBay: http://goo.gl/NBURFm, link will expire!) to create a scrolling text effect! The font used is from my standard graphics library, originally from the Adafruit graphics library. I’ve modified the text size from 5×8 to 6×8 in the […]
In addition to my previous post about the ADXL335 accelerometer, I’ve now added some basic calibration! The datasheet for the ADXL335 (http://goo.gl/LAslK) does actually state the voltages that the accelerometer should produce with respect to the actual level of acceleration though as some may know, the value of gravity varies dependent on where about you […]
