I've gone and bought a PicoScope 4224 as I'm messing about with the CAN bus and was advised that that was the way to go. Managed to install The Windows on a laptop and have The PicoScope 6 (22.214.171.124) installed on it.
Everythin' good now apart from getting this scope to trigger on the CAN signal comin' out of a microcontroller. I have a led flashing and of course when I connect the probe to that connection I can trigger every time. Now move the probe to the CAN connection and I'm either not getting a trigger at all, or I'm getting a trigger some time (seconds) after the event. In the case where I do get a trigger after the fact I can see all the negative pulses that were missed by the trigger. And of course I miss the start of the CAN Message. I know that the CAN message is going through as I've got another module on the BUS picking up the message and lighting a led. Every time the message gets sent the PicoScope just sits there scratching it's head and whistling in the wind.
In addition to that is there a way to get the scope out of the trigger mode? At present I have to kill the SW and restart it to get rid of the triggering yellow diamond. If I'm not trying to trigger I can watch the wave form going by without learning anythin' about it, but at least I see it going past. Try to trigger and all I see is a yellow diamond.
