STM32F0 – Software capacitive touch

Capacitive touch is “rad”. By utilizing one of the simplest physical characteristics of an object – charge storage, one is able to measure the presence of a grounded object including touch and pressure. There are a couple of capacitive touch libraries that I’ve seen around but many require dedicated hardware, for example the TSC peripheral […]

Update 21-8-15

Well, its been an extremely long time since I wrote a blog post and sadly this one is a short one too! 😦 Over the summer, I’ve been working at Imagination Technologies again and going from a lazy student to full time work really takes it out of you. I will however resume my blog […]

STM32F0 RTC using HSE/32 as the timing source

This is only a short post really. With my watch, I’d been trying for AGES to try and get the RTC working with the external crystal. It might seem simple to some but it was certainly not simple to me and ST don’t give an example, unlike most things; in their standard peripheral downloadable pack. I […]

STM32F0 Tutorial 2 – SysTick

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 […]
