Nuclear Pioneer MCA 4.05 firmware update

 4.05 firmware update released for Nuclear Pioneer MCA. Now you can download the latest firmware file including programming instruction PDF here:

https://rhelectronics.net/store/nuclear-pioneer-mca-multichannel-analyzer-firmware-updates

What is new in 4.05 software:

1. Added second color theme for gamma spectrum with higher contrast. You can switch the spectrum color by making several turns of the encoder pointer toward 0keV direction. The encoder have to be in pointer control mode.

2. Added Th-232, Ba-133, Lu-177 isotopes to the auto-detection library

3. Added N.O.R.M. mix detection with mixed Ra-226 and Th-232

4. Improved peak detection

5. In scint.mode, the counter will make the event beep for every n=100 detected particle for large crystal or for every n=25 detected particle when small crystal is used. You can set crystal size through serial monitor command as described in the manual.

All previous bug fix and updates from 4.01-4.04 are included in 4.05

You may need to recalibrate LLD, HLD, doserate factors, timestamp and energy scale after making firmware update.
