Firmware update 4.14 released for Nuclear Pioneer RIID

Firmware update 4.14 released for Nuclear Pioneer RIID based on Cortex-M4. You are welcome to download the latest firmware file including programming instruction PDF here:

Nuclear Pioneer MCA Firmware | RH Electronics

What is new in 4.14 firmware:

1. In scintillation mode added Waterfall Histogram for energy distribution and CPS intensity estimation. The scale has the same zoom settings as the main MCA window: 512-4096 channels.  Waterfall zoom can be set in the LCD ZOOM X menu.

2. In scintillation mode added basic identification for Am-241, Cs-137, Ra-226, U-235. Please note, scintillation mode identification does not replace the main MCA RIID mode and has less performance of the identification results compared with the MCA mode. However, it can be a nice add-on along with the new Waterfall Histogram.

3. Fixed bug in CSV file date. Now the day and month of the recorded CSV spectrum are displayed correctly.

4. Improved activity calculator. Now it has a better precision function to get efficiency for the selected geometry. You may need to re-calibrate the correction factor in the activity menu.

5. Improved geometry selection menu. Now the menu scrolling list starts with the previously selected crystal size. 

6. Fixed a few small bugs in the internal maintenance. 

7. Added internal test for erratic value or temperature sensor disconnection. Now if the sensor read wasn't completed, the temperature readings will be displayed as "--.-" until the next read try.

Electronics intended to wotk in temperature range of 10C-30C, try to install the SiPM detector close as possible to the thermistor sensor on the PCB as shown on the diagram.

Windows OS detects the board as an USB Audio device, that's why you can start to use your favorite freeware MCA without additional audio card or any adapters. Just solder USB cable and open Theremino, PRA or BecqMoni2011 MCA.

Calibration process is simple!

1. Set recording audio level to 99%, set playback audio level to 0% in Windows drivers
2. Set Theremino Audio Gain x1 and 192kHz sampling rate for the USB device
3. Set Theremino Energy Trimmer to the middle
4. Apply Cs-137 and adjust SiPM voltage bias potentiometer to place the 662keV at correct position
5. Check the bias voltage on SiPM cathode is below 31V and re-adjust Energy Trimmer or Bias (if required)

Firmware 1.06 update for MCA ver.1 boards!

1.06 firmware update released for the MCA ver.1 boards! It include supporting of UART-USB logging with the PC Utility software. You can download firmware update and utility software from the rhelectronics website.

https://rhelectronics.net/store/diy-pic18-mca-kit-for-gamma-spectroscopy.html

What is new in 1.06 firmware:
- UART Mode for live spectrum transfer
- Added new hex format for SD file (faster saving)

Firmware can be uploaded to the module with Pickit programmer. To start using UART-USB all you need is CP2102 USB-TTL module to connect the MCA with the computer.

The PC Utility software will do: live spectrum, import and export CSV, SD file convert from hex to CSV, export spectrum screenshot and bin to energy calibration. PC Utility software working as a passive receiver, I'll post communication standards of the MCA unit if you want to implement your own UART data receiving of the gamma spectrum from the MCA.
