Sunday, everybody’s least favourite weekend day at the thought of having another 5 days until time is no longer scarce! I’ve been getting down to a fair bit of VHDL programming, one program I wrote recently was an attempt at a brushless DC motor. I managed to get the outputs 120deg out of phase but […]
On any microcontroller, timers are arguably one of the most useful peripherals, probably along with GPIO. What is a microcontroller without the ability to measure time reasonably accurately?! Timers on the STM32 series of chips are quite complex and will be spread across multiple tutorials, each hopefully demonstrating one useful section of timers. The tutorial […]
One of the most cool features of the ARM Cortex series of processors is the SysTick. The SysTick is a 24 bit timer with a user configurable prescalar which can be used for simple variable incrementing tasks such as incrementing a second counter or similar. For the example of done, I’ve made the SysTick counter […]
Its been a pretty hectic exam period (It hasn’t really, I just didn’t really know what to start the post with!) but I’ve regardless managed to finish Watch 1, finish most of the construction of Watch 2, design and send off for Watch 3 and learn a fair bit about Visual basic along with way! […]
So I’ve finally got round to writing my first tutorial! This first tutorial will be on using the STM32F0 with simple GPIO ports. I’ve set it up so that the LED’s will alternate depending on whether the push button is pressed or not. I’m using Coocox for my IDE and there are loads of other […]
Today has actually been a really successful day! I finished the routing of Watch 3 and sent the gerber files to ITead Studio for them to be developed into PCB’s, managed to get my personal Bluetooth packet system working and had a tasty postal order through! One of the things that came in the post […]
Well, today has certainly been a productive day! I recieved my new HC-06 bluetooth module (I stupidly ripped up the RX trace on the other one trying to unsolder it from the backboard) and have managed to implement the “harris protocol” system! I’ve gone for a really simple protocol as the module itself only sends […]
3 blog posts in one day! So today, along with my Farnell arrival came the magical package from the far lands of Asia containing my Watch 2 PCB’s! Choosing a black solder mask really brings out the PCB shine and makes the product look more professional already! For only $6 extra, I’d say its worth […]
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 […]
After doing a bit more research into homemade smart watches, I came across this brilliant forum article (http://goo.gl/7mI1Dm). This guys watch is utterly amazing and uses a memory LCD. These LCD’s are quite out of my price range at ~£14 each! So after another eBay search, I found a total 1.44″ gem (http://goo.gl/3Tfg7e Link will […]
