greeeg 460 Posted April 4, 2014 Author Share Posted April 4, 2014 Got my components, soldered up the first completed controller board. The small level shifter, is designed around a dual n/p mosfet. This will probably be changed to a dedicated level shifter in the future. Due to gate capacitance of the mosfets, the output isn't as square as the input. Luckily it gets close enough to work. This is mainly due to the high frequency of the LEDs signal. The accelerometer is connected via IIC, which I have never used extensively before. I still haven't worked out the repeated start condition, which the accelerometer requires for individual register reading. so it's proven that the G2553 has enough grunt to run all 120 LEDs. 70% of RAM is used as a rgb framebuffer, with 152 bytes left there is still plenty for some rich applications. And since people don't read anything these days here is a video. (sorry about the audio, I thought I should pick something ) Even though I've bought a fancy DSLR photographing/filming LEDs is very difficult. I've been experimenting with settings, but this still does look better in real life. bluehash and RobG 2 Quote Link to post Share on other sites
