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 […]
The 74HC595 (http://goo.gl/J9ILXZ) is a great chip for expanding output only GPIO and is normally really cheap. Normally, you bit bang an SPI like interface to send data to it but I decided to test whether it actually works using an SPI peripheral. With my trusty STM32F0 Discovery board and my good ol’ oscilloscope, I can […]
Last year, I came across the Maple Mini microcontroller (http://goo.gl/G5579s) which is an ARM based arduino equivalent that came before the arduino due. It really helped me jump into the world of arm controllers and I think that its a really great little board! Unfortunately, they stopped support for windows quite a while back and […]
Another cool buy that I’ve found on eBay is a 8×8 LED matrix powered by the MAX7219 (Example: http://goo.gl/lkyY4c). Its really easy to interface and uses SPI which I’m beginning to think is my favourite protocol! The STM32F0 is a pretty high quality processor based on the ARM Cortex M0 and doing a simple 8 point […]
