STM32 Mini Computer

Hi again.
Today I’m going to talk about my mini computer I started making with the STM32.
It’s powered by the STM32F103RET6 stamp board from Futurlec, and it is clocked at 72MHz. Right now there isn’t any “real” applications or games in it, but theese are under development.

You can see some pictures about it here, but I’ve also made a video where you can see it in use.

The buttons on the right side of the menu is from Microchip’s Graphics Library, which I ported to the STM32.

STM32 Oscilloscope

This week I got some inspiration from the ST DSP library, so I made my own oscilloscope with the STM32 and my 320x240 pixels QTFT screen. I made the code from scratch, both the sampling and screen updating code -- but I used the ST DSP library for the FFT calculations of course

You can see the video of the project here…

STM32 Nokia LCD

Finally I found how to use the Nokia LCD I’ve bought from Sparkfun a year ago.
Originally I bought the display for the Arduino, but as the LCD is 3.3V I tried to make a voltage convertion circuit, but it didn’t work
But now, I’ve got the STM32 which is running 3.3V – so I could just connect it directly… And then it worked!
