Class Summary

HelloWorldWithJna	The purpose of this classe is just to test jna with a very basic example : Helloworld.
TestBenchMainModule	This is the main module for the control software of the APC test bench.
TestCanfestival	Just for testing JNA : a better solution is to do the job in a C file and communicate to this C file with a TCP proxy.

Package org.lsst.ccs.subsystems.fcs.testbench Description

This package is for the test bench installed at APC with a PC104 and two Can Open Devices : an ADC and a DAC. Its purpose is to test the communications between the CCS and the control software of the test bench. The control software of the test bench has 2 parts : - a Modular Subsystem, which is a subsystem of the CCS and written with the CCS framework - a C program which handle the can open devices : it translate the commands comming from the Modular Subsystem in commands that the ADC and the DAC can understand. To do this translation, it uses the open source C library canfestival.. The PC104 has 2 can bus interfaces and is connected to one or two Can Open device. The PC104 with its can bus interfaces is a Can Open Master Device and the 2 other devices on the Can Bus are Can OPen Slave Can Open Device. The APC test bench is made of one PC104 and 2 can open devives : - a 8 analog inputs (CAN_CBX_AI814) - a 4 analog outputs (CAN_CBX_AO412) A thermometer is connected to the analog inputs and a led is connected to the analog output. One of the OUTPUT of the DAC is connected to the INPUT of the APC, so we can test if the value we write on the DAC is the same value we read on the ADC With the TestBenchMainModule, we can read the temperature, turn on or off the led or start an automatic mode where the temperature is read every tickmillis seconds. When the temperature reachs a given value, it turns the led on, otherwise, it turns the led off. This package should not survive after camera construction. The communications with the Can OPen devices are done by the C programm, testadcdac, which relies on the canfestival C-library. The Wrapper and the TestBenchMainModule communicates over a TCPIP connection.
