BNMR: Hardware Debugging
Introduction
Test programs have been created for some of the DAQ VME modules in use in the BNMR/BNQR experiments. The test programs are built alongside the main frontend and logger programs.
| Module | ProgramName | Purpose |
|---|---|---|
| PulseBlaster PPG | vppg_interactive_32bit.exe | test program for PulseBlaster PPG |
| TRIUMF PPG (PPG32) | tppg_interactive_32bit.exe | test program for TRIUMF PPG32 (not used by bnmr / bnqr yet) |
| SIS3801 | sis3801_interactive_32bit.exe | test program for SIS3801 scaler |
| SIS3820 | sis3820_interactive_32bit.exe | test program for SIS3820 scaler |
| PSM | psm_interactive_32bit.exe | test program for PSM RF module |
| PSMII | psm2_interactive_32bit.exe | test program for PSMII RF module |
| PSMIII | psm3_interactive_32bit.exe | test program for PSMIII RF module |
| NIMIO | bnmrbeamsim_32bit.exe | test program for NIMIO32, inclusing simulating BNMR beam/helicity flipping |
All the 32bit programs must be run on the VMIC (not the host computer). The non-32bit programs must be run on the host computer.
PSM
The test program psm3_interactive_32bit.exe tests the PSMIII module.
This is a menu-driven program. It can be run (with caution) at the same time as the DAQ, as it does not automatically do any initialization. The module's registers can be dumped by using the 'Dump Registers' command.

PPG
The test program vppg_interactive_32bit.exe tests the PulseBlaster PPG module.
This is a menu-driven program. It can be run (with caution) for debugging at the same time as the DAQ, as it does not automatically do any initialization. For example, it can be used to check whether the PPG is running.

SIS3820
- Note
- The sis3820 must be used in non-DMA mode. The DMA mode does not work
The test program sis3820_interactive_32bit.exe tests the SIS3820 scaler.
This is a menu-driven program. It can be run (with caution) for debugging at the same time as the DAQ, as it does not automatically do any initialization. For example, it can be used to read the control/status and operation mode register.
Several test procedures are provided. For example, test1 runs a test using the internal 10MHz clock as the LNE source, then reads out the data from the FIFO.
NIMIO32 / beam simulator
The test program bnmrbeamsim_32bit.exe tests the NIMIO32 and provides a tool for testing when real beam/helicity inputs are not available.
This is a menu-driven program. It can be run (with caution) for debugging at the same time as the DAQ, as it does not automatically do any initialization. For example, it can be used to read the control/status and operation mode register.
The main menu provides a generic interface for the NIMIO32. Use the S command to enter a sub-menu of commands specific to bnmr and bnqr.
