Summary
There are a few module constants used to direct communication with the MCA-3K
Module Constants
The constants specify the on-board hardware target (ARM or FPGA) and the address within the target.
| Module communication constants | |
|---|---|
| Constant | Description |
| FPGA_WRITE | Command type: Write to FPGA |
| FPGA_READ | Command type: Read from FPGA |
| ARM_WRITE | Command type: Write to ARM |
| ARM_READ | Command type: Read from ARM |
| MA_CONTROLS | Command address: FPGA control registers |
| MA_STATISTICS | Command address: FPGA statistics registers (used for time and count rate measurement) |
| MA_RESULTS | Command address: FPGA results registers (version, telemetry) |
| MA_HISTOGRAM | Command address: FPGA histogram memory |
| MA_TRACE | Command address: FPGA oscilloscope trace memory |
| MA_LISTMODE | Command address: FPGA list mode memory |
| MA_WEIGHTS | Command address: FPGA summation weights |
| MA_ACTIONS | Command address: FPGA action registers, eg to start data acquisition or clear previous data. |
