Hi,<br>My program "ViewPort" lets you use the Propeller as a 40Mhz Oscilloscope when used with a $5US Analog Digital Converter. If more were interested I might be able to put together a "daugherboard kit" - my current solution involves a lot of fine soldering.<br>
<br>ViewPort has most of the features of the competing usb scopes: triggers, cursors, timescales, save to csv, spectrum analyzer, logic state analyzer and much more. It's worked very well for me and let's me measure anything from low speed sensors to NTSC video...<br>

Mine is a stingray from dontronics across the ditch.<br>

For what I need, its been good. Fairly simple to use but not rated for<br>
really high speed signals.<br>
I note that the dual channel one is only a smidge more now though.<br>
