Its been a fair bit of time since I last posted, mostly attributed to the fact that I’m no longer living down south and have moved home for the next two weeks until I return to university! None the less, after re-arranging my room at home to my liking (my family have the obsession of […]
Well! Apart from having a nice little travel into London to see the family and a haircut, what have I been up to today you ask? The answer to that resides in my Colour graphics library! Its not very often that I improve on my libraries unless I need to, or I’m bored as I’m […]
Well in light of my recent hardware addition, I’ve decided to convert the basis of my HD44780 code into a standalone library. I’ve also added the ability to print signed integer numbers with padding with my whole code including examples compiling to < 3.5k at O0 optimization! Snazzy or what, with O3 optimization, I’ve managed […]
And voila! As I said in one of the last two posts (Initial post: https://hsel.co.uk/2014/08/14/stm32f0-discovery-board-and-the-hd44780-lcd/ and integrating a charge pump for backlight control: https://hsel.co.uk/2014/08/14/stm32f0-discovery-board-with-hd44780-and-integrated-charge-pump/), I’ve now included a generic LED backlight PWM controller using one of the standard GPIO pins. I’m using GPIOA Pin 6 to drive the LED backlight and I’ve integrated a 4bit (16 step) backlight […]
Upon my return from my Central Europe tour (realistically – Belgium and Germany), I had the parcel everybody loves, A lovely little cuboid from Itead Studio! Contained within were my Eon Smart Watch 3 PCB’s, the ultimate model. As with always, I set to building then pretty soon after receiving the PCB’s as they were […]
After much contemplation, I decided to rewrite the original ILI9163 library that I was using for the LCD. Fortunately, the LCD manual was much easier than I thought to read (http://goo.gl/CNVU8V), so tonight, I went about rewriting the whole LCD driver. I didn’t include any of the gamma correction curves as that would require a […]
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 […]
Well! Even after a bit of a dodgy design, I’m happy to say that the PCB’s have quite good success! I’ve now linked up the menu and mainboard PCB and have got the menu successfully working! The PCB’s in shot showing the main board and menu linked. Even though the center button on the menu […]
Today, using one of my favourite PCB companies ever, I sent off for my Phobass IV PCB’s to be made! I didn’t get round to designing the “string” PCB as that will require much more though and I’m wanting to jump right into finally completing IV! I’ve also fully completed the menu system and at […]
Having had a drastic rethink over the whole Phobass design, I’ve decided that I’m going to scrap the idea of making the patch editing PC based and have a dedicated patch editor onboard. Using my trusty PCD8544 Nokia LCD and the library I wrote, I’ve been writing a menu system. So far, I’ve got the […]
