STM32F0 CubeMX Tutorial 1 – GPIO

It’s certainly been a while since I wrote a tutorial, a lot of the STM32 ecosystem has changed and its probably time I changed with it. CubeMX was developed by ST to streamline application design and creation. It allows for a visual method of generating initialization code without needing to know the ins and outs […]

The Neon Clock – Part 2

Today, my PCBs arrived, wahoo! Therefore I’ve been able to have a quick go at making my neon clock. I tested it in parts to make sure each section worked before putting it completely together. Unfortunately, my high voltage PNP¬†transistors haven’t arrived yet so I’m currently testing it with TO92 transistors in their place. Testing […]

The Neon Clock

Building a clock really is about as textbook as it gets when it comes to electronics projects – especially on the internet. I however have never build a clock (not intentionally anyway… I wouldn’t count the measily effort of my smartwatch!) so I’ve decided to have a go at one. Instead of doing one of […]

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 […]

SDRAM + VGA + FPGA = SPI Addressable graphics card!

Having already written an SDRAM based VGA controller, I’ve finally got round to writing a simple SPI module that allows my STM32F0 discovery board to write to the SDRAM during blanking. In the video above, I hadn’t implemented a “busy” pin so my STM32F0 was spamming pixels regardless of whether there was blanking or not. […]
