===== User Guide ===== 

The system is equipped with an LCD which displays information about the state of the load such and together with the 3 push buttons placed below it can be used to display and configure different system parameters. The **+/-** buttons are used to navigate through the system's menu and to change different system parameters, while the **Enter** button is used to confirm parameter changes or to enter / exit the menu screens.

===== Analog Discovery™  ===== 
In order interface the Dyno with the Analog Discovery™ USB Oscilloscope:
  * Slide switch S2 to EXT_CTRL position
  * Insert the Analog Discovery™ in P1 the connector(with the Analog Devices logo facing the user) 

{{:resources:eval:user-guides:ad-fmcmotcon1-ebz:hardware:dyno_discovery_control.JPG?400|Dynamometer Drive System}}

Two software packages are available for interfacing with Analog Discovery™:
  *[[http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,66,849&Prod=WAVEFORMS|Digilent® WaveForms™]]\\
  *[[http://www.mathworks.co.uk/help/daq/examples/getting-started-acquiring-data-with-digilent-analog-discovery.html|MathWorks Analog Discovery toolbox ]]\\

The signals available to the  Analog Discovery™ are:
^ Dyno Signal ^ Analog Discovery channel ^ Description ^ 
| I_A | Scope Channel 1 Positive | Phase A motor current (185mv/A) | 
| I_B | Scope Channel 2 Positive | Phase B motor current (185mv/A) | 
| PWM1 | Digital Channel 0 | Phase A PWM (3.3V levels) | 
| PWM2 | Digital Channel 2 | Phase B PWM (3.3V levels) |
| PWM3 | Digital Channel 2 | Phase C PWM (3.3V levels) |
