Propeller Activity Board WX

Tapperman

I’m back. After a few years, things sure have changed. I purchased an Activity board WX. And I can’t find any examples of how to use the A/D or D/A. No chip numbers … nothing.

Any help would be appreciated.

Welcome back Tim !

I've attached the schematic so you can see what's going on.

The last page has the ADC labelled U13. Part number : ADC124S021CIMM
The DAC is just an opamp, labelled U12. Part number : MCP6004T-I/ST

Learn has some resources with C code or BlocklyProp, for example here: https://learn.parallax.com/courses/propeller-c-simple-circuits/lessons/measure-volts/

Couldn't find a SPIN example yet - maybe Jon will have something to share-- else I'll take another look too.

I have an object for the ADC124S021. Since I hadn't used it in a long time, I freshened it and knocked together a quick demo. It works.

JonnyMac, thankyou for info.

Bonus, loved the format string used in the terminal object.
