lzoDSO – todo for today: timer driver

Posted by June 11, 2013

Will work on the timer driver code (legacy and fresh one) to allow selection of the actual hardware timer to use (the on-chip ones that are part of the ATmega series micro controllers).

When things are working, I’ll be able to finally enable the test signal output on the front panel controller board of the lzoDSO.

Just burned a 10K poti … I hate when that happens, which is somehow discouraging.

I was trying to replicate my own NE555 timer circuit (see wiki page) on a breadboard. This circuit will be the central piece of a signal/function generator I’m building.

For now it is simply an oscillator, but  I will add a circuit which will convert the oscillator signal to different wave forms (sinus, triangle, saw tooth). Later on I’ll also add a micro controller to be able to have the device controlled using a serial interface or USB and give it a display and some keys.

I have already drawn a schematic and worked on a board layout, even though the thing is not totally finished. So, if you are interested, checkout the schematic and layout files from this directory in the labs repository (there is also a wiki page but its content is in a draft state).
