Preface I’m currently doing a project that uses a tiny SSD1306 based OLED display. I’ve searched all over the internet but couldn’t actually find any data on current measurements done by people so I thought I’d do a couple and put them up here! The OLED I’m using is a standard 128×64 pixel version that […]
Its been one hell of a while since I posted a tutorial so I thought I’d throw one of up for this. I’ve not had much time to do much electronics as of late (it is now my job…) but hopefully once I move into a new area, I’ll have a little more free time […]
I’ve previously got the STM32F0 discovery board working with a FIFO (AL422b) version of the OV7670, not a particularly hard feat and many others have achieved this across the internet. From what I can find however, nobody has managed to interface an OV7670 with an STM32F0 without external memory or a FIFO! Today however, thats all […]
So I did this project a looooong time ago (Actually around this time last year…..) where my FPGA was acting as a video controller for the STM32F0. I’ve recently improved (or I’d like to think I have given my final year project) my VHDL skills so I thought I’d give this another shot. I completely rewrote […]
(Its now 4/5/17 shhhh) Frame So last night I was in the hackspace testing out my new hinges and moved actuator. Sadly, the hinges once again were too weak to fully support my weight (ugh) so it’s made me rethink the design of each leg. I am however going to keep the hinges for now […]
After the faults with controller board 1, I wanted to respin another controller board ASAP. These boards arrived yesterday and with a swift order from RS, so did a load of components! On the previous board, I was using a large STM32 device with many pins and driving the motors directly through level shifter chips. […]
Half man, half (ant, beetle, grasshopper, cockroach…), the ultimate dream of creepy sci-fi locomotion. I’m sat here with a 6 legged centaur like image in my head, somewhat like the Scorpion King from The Mummy (exceptional 1999 CGI). Probably about the strangest intro to a post I’ve ever written but hey! It’ll do. This is […]
A couple of people had requested that I give some example code on using the I2C peripheral in an interrupt controlled manner. By using it in this manner, the processor can achieve other tasks while also doing I2C transactions giving a multi-tasking feel to a program. In this example, I combine using the DRDY output […]
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 […]
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 […]
