A couple of people had requested that I give some example code on using the I2C peripheral in an interrupt controlled manner. By using it in this manner, the processor can achieve other tasks while also doing I2C transactions giving a multi-tasking feel to a program. In this example, I combine using the DRDY output […]
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. […]
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 […]
Well! I’ve had a fair few requests in the past few weeks about how I got the HMC5883L digital compass IC working with my STM32F0 discovery board (as shown in a previous post: https://hsel.co.uk/2014/05/29/hmc5883l-magnetometer/). I’m really not a fan of the I2C implementation on the STM32F0 discovery board as many things don’t seem particularly apparent at […]
As with nearly all cool electronic devices that I buy, this one too came from the foreign lands and was off eBay (http://goo.gl/jbcKE6 – Link will expire as with all eBay links)! One of the features that I’ve wanted to have in my watch that I’d actually find really useful is the ability to have […]
