I bought a couple of months ago a little AVR Dragon card. My initial plan was to use it for debuging programs with the embbeded JTAG. But I run into several issue with that, mainly because the lack of doc … Continue reading

I recently bought 2 LCD from jckrers ebay store. I have a good idea for this stuff, but first I need to run several tests. This LCD are fine and use the common KS108 controller. My first thought was to … Continue reading

In the previous article, I have study the way to power this large VFD, now we gonna take a look closer at the logic itself. We need to drive a lot of bits (8+9) at ~40v. After a little googling, … Continue reading
