Welcome in the forum, Richard!
In Creator go to Project -> Build Settings -> Linker -> General
Add "m" (without the quotes) into Additional Libraries. This will add the math library "Libm.a" to your project.
as alternative you may also consider fast thermistor calculator, which was made for higher precision and speed than Cypress's stock component is providing:
Thank you Bob and Odissey1 for your suggestions. It's nice to be back on the rails!
Oddly, adding the "m" didn't fix the original project but did fix my minimalist project. I had to rebuild the project from scratch with the "m" added from the start. Otherwise I got a different raft of compiler objections.
I'll look into Odissey1's work later as it's interesting and useful for another occasion. This current project is just a toe-in-the-water exercise that is a thermal monitor to go in one of our products as an add-on. It needs accuracy of about 2 degrees at best! But it gives me a chance to get some practical experience with the PSoC goodies.
Once again, guys, many thanks for your assistance.
You're always welcome, Richard.
