Releasing new version of freq_pi for Raspbery Pi
Released under the GPL license.
This version has a frequencty sweep mode.
Range is from very low audio kHz to very high VHF MHz.
You can set start, end, and frequency increment, as well as the time to wait between steps.
It also has a trigger pin input with selectable polarity, to start the sweep,
Output is a square wave.
Nice to test filters.
No additional hardware required on the Raspberry. Just a quick hack.

Range from about 150 kHz to above VHF.
This version as a scope triger output, just sweeped my scope with it. You can sweep anything that way.
That just worked thank you.
After sweeping, it continues to generate the last (end) frequency. I would have thought it should reset to "off"
What command can I send to kill the output? (switch off pin 4) Is that function tied up with pin 24?
TIA

The latest version, -0.6
No.
Version 0.6 does the job, thanks for what I believe to be a really useful program.
