Installation and Building

The latest version of this module has been built and used on EPICS 7.0.6.1 but should work on earlier versions. The code uses the EPICS devLib APIs for VMEbus access, so it can be run on any target that provides EPICS VME support.

Unpacking the distribution tar file produces an EPICS support module directory tree named after the module.
Edit the configure/RELEASE file and set the path to your installation of EPICS_BASE.
Run make in the top level directory and check for any compilation errors.

Application Builds

In order to use the support in an application do the following:

Add the following to <top>/configure/RELEASE

ACROMAG=<full path to installation directory>

Add the following to the application Makefile.
```
<app>_LIBS += acromag
```
Add the following to the <app>Include.dbd file for older EPICS versions:
```
include "avme9440.dbd"
```
For newer EPICS versions, add a line like this to the Makefile that builds the IOC application:
```
<app>_DBD += avme9440.dbd
```

VME Configuration

The following configuration command is provided for use at IOC startup:

    devAvme9440Config(ncards, base, vector)

where

    ncards - number of modules. The default is 0.
    base - the VME A16 address for the first card. The default is 0.
    vector - The interrupt vector for the first card. the default is 0.

VME cards must be configured at adjacent addresses in the VME A16 space.

EPICS Device Support

This module provides device support for the EPICS bi, bo, mbbi and mbbo record types. Set DTYP to AVME9440 I for the input record types, and to AVME9440 O for the output record types.
