A Defines Request

[Kirk Fraser]

I'd like to explore my theory first, considering my accomplished tests sufficient proof (so far) that the two global commands don't help in my circuit. What other commands are there to try? What commands would convert or leave the 3 essential pins analog and make the rest digital?

This seems reasonable since the PWM outputs are analog signals and driving the IRL530's with a solid digital on could act like a short, allowing coil current to build and eventually blow things up. This could explain the blown chips with the global commands.

The "normal" inaction with the POT input may also be affected by a more specific analog input, compare, or conversion command. The exact same POT circuit was used successfully with the Stamp, with the exact same RCTIME command. RC means Resistor-Capacitor so it is necessary for them to be in parallel to create a measureable oscillator time change when the POT value changes. I don't know why it is connected to ground instead of 5+ but I got that circuit from Stamp docs. Perhaps a different setting for that pin is needed to accept analog input from ground instead of positive values.

I don't know how the guts of the Analog - Compare commands work, if there's any need to know. I do think finding pin specific commands would be a step toward a solution. What section of the book are those in? Thanks.
