After managing to get my graphics controller working at a mediocre resolution of 100×75, I wanted to squeeze as much performance out of this chip as possible! Unfortunately, due to memory constraints, this meant rewriting the VGA controller to work at a different resolution. The original controller was running at a resolution of 800×600, which […]
Well, this week so far has been very productive with regards to electronics! This is a project I’ve been wanted to do for ages just haven’t got round to doing. I’ve previously designed VGA controllers on both my CPLD and my FPGA board but I’ve not actually done anything useful other than design a bouncing […]
To all who haven’t had chance to read part 1 yet, it can be found here. So! In the previous post, I designed a pretty simplistic graphic analyzer. I’ve since upgraded it to display the frequency range (dependent on the sample rate), along with redesigning the analog input stage. Playing a bit of Dillinger Escape […]
What’s cooler (than being cool, ice cold? no…) than having the ability to view the spectrum of audio?! A few things I hear you say, to which I also agree. On the other hand, viewing the spectrum of your music can be a fun and “wow factor” way to show off how electronics can do […]
Wahoo! With two exams down, I have my last one this Wednesday and nearly all of my free free time (time not spent skating and revising) has gone to improving my watch. Its actually getting to the point now where I’ve got so much code that without optimisations, it doesn’t all fit on! I’m currently […]
The ADC in the STM32F0 series of microcontrollers is pretty advanced compared to similar costing equivalents, offering features such as continuous conversion, internally and software triggered conversions, channel scanned conversions, amongst much more! This isn’t a proper tutorial but I will be posting the code on how to achieve such a task and how I […]
Fueling off my desire for wearable navigation, I’ve decided to try and use the simple HMC5883L magnetometer module to create a simple non tilt-compensated compass. As the name suggests, it currently only works on flat surfaces and tilting it will give a pretty erroneous result! None the less, on a flat surface it pretty much […]
Well after popular demand (lol two people…)! I’ve revisited some EXTREMELY old code and got it working for my ILI9163 LCD, its not pretty, its code I’ve not used in a LONG time and probably won’t use for a long while more but as far as I know, the driver is pretty sound. Its uncommented […]
Well tonight has been productive! I’ve managed to get the DS1307 working with my STM32F0 and now the AM2302! I thought that I’d actually done a previous post on interfacing the DHT11 humidity and temperature sensor but it turns out I hadn’t! The method of operation and data transfer is pretty much the same so […]
One of the many things I bought a while back was a small PCB containing a DS1307 RTC (http://goo.gl/rfdL78) along with an EEPROM IC (not interfaced in this post…). The DS1307 as far as I know is the universal standard for RTCs offering BCD storage of time and date, along with some user accessible space. […]
