I did firmware 1.03 update for the MCA module, if you want to update please contact me by email. If you have any suggestions before I make the final compile please let me know too:)
Software 1.03 update summary:
1. Set LCD ZOOM RANGE in menu. Added LCD zoom. You can set number of channels to display on LCD from 128 to 1024.
2. Set LCD FIRST CH. Related to LCD zoom, you can set the first channel for LCD zoom range.
LCD zoom settings has no influence on SD data file. As before, the log. file will contain all 1024 channels.
3. SET MIN CH and SET MAX CH functions where updated. Previously it was used only to filter out noise channels on top/end of a spectra. Now it also allows to select a specific region and ignore all peaks beyond. On SD file, all filtered channels will be saved with zero value.
Be careful not to overlap minimum and maximum channels, otherwise the MCA will not capture any spectra.
4. REMOVE NOISE CPS when enabled, allows to show on LCD only relevant CPS counts in range of minimum / maximum channels. When disabled, all CPS events are counted for LCD. This function can be useful when you debug the noise level of your system or want to estimate full spectra CPS vs. activity for selected region.
5. Added sound/melody notifications on RA6 port of the processor. For PCB version 1.00 you can wire an external components to drive a little magnetic buzzer.
6. SET MAX TIME increased up to 7200 seconds to capture longer spectrum.
7. Fixed initial zero spectra bug that occurred without incoming signal in firmware 1.00
