ADM TEST

The program is designed to test the operation of the module with the FPGA project ADM.

Features

  • Display information BAR0 - list of control units
  • Display information BAR1 - list of control units TEST_CHECK, TEST_GENERATE
  • Checking of the data input from TRD_MAIN
  • Checking of the data input from DIO_IN
  • Checking of the data output to the DIO_OUT
  • Synchronous data input from the DIO_IN and data output to the DIO_OUT
  • The calculation of the current exchange rate - in the interval 4 seconds
  • Calculating the average exchange rate - with the launch of
  • Error logging

Source code

The source code of the program is in the repository: trunk/soft/linux/application/adm_test

Catalogs:
  • bin - executable and configuration files
  • src - source code
Catalog src
  • Makefile - for build
  • work - source code
The program uses the files in the directory trunk/soft/linux/common/
  • pex - contains class files: pex_board
  • utils - contains useful files

Starting the program

Before starting the program you want to load driver pexdrv.
To load the driver script is used insert from the directory soft/linux/driver
Loading the driver: sudo ./Insert.
Unloading Driver: sudo rmmod pexdrv

To view a list of available devices can run the command ls /dev/AMB *
The device name is formed as follows: /dev/<device name> <sequencenumber of the device>
For example: /dev/AMBPEX50

Launch:
./adm_test <device name> <configuration file> [<configuration file>]

  • <device name> - logical device name, for example /dev/pexdrv0 (not currently implemented, is always used pexdrv0)
  • <configuration file> - cfg file with parameters
List of configuration files:
  • test_main.cfg - inputs from the TRD_MAIN
  • test_dio_s128.cfg - inputs from DIO_IN
  • out_dio_s128.cfg - output to the DIO_OUT

If given two file that runs two of the testing process, if only one file is only one testing process.

Example:

Command: ./adm_test test_main.cfg
Output:
