There are a few module constants used when directly communicating with the MCA-1K via the API.
The constants specify the on-board hardware target and the address within the target.
Module communication constants |
Constant | Description |
ARM_WRITE | Command type: Write to ARM |
ARM_READ | Command type: Read from ARM |
ARM_VERSION | Command address: Version information (read only) |
ARM_STATUS | Command address: Status data for operating voltage and temperature, results from data acqusition (R) |
ARM_CTRL | Command address: Parameters controlling data acquisition, alarming and gain stabilization (R/W) |
ARM_CAL | Command address: Lookup tables for voltage vs temperature and similar data used for gain stabilization (R/W) |
ARM_HISTO | Command address: MCA data with statistics and histogram (sample) |
ARM_BCK | Command address: MCA data with statistics and histogram (background) |
ARM_DIFF | Command address: MCA data with statistics and histogram (sample-background); ie background-subtracted histogram and count rates. |
