DS_DMA

h1. ADM TEST 

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

h2. 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

h2. 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

h2. 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.cfg* - inputs from DIO64_IN

* *out_dio.cfg* - output to the DIO64_OUT

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

h2. Example: 

Command: *./adm_test test_main.cfg*
