Evaluation environment setup

The evaluation environment is composed by:



One or more EVAL6470H\PD or EVAL6472H\PD.



One STEVAL-PCC009V2 demonstration board.



A USB cable.



A stepper motor with a small mechanical load (unloaded stepper motors suffer of

strong resonance issues).



A power supply with an output voltage within the operative range of the evaluation

board.



A Windows® 7 or Windows XP PC with a free USB port.



The SPINFamily evaluation tool (the last version can be downloaded from the

STMicroelectronics® website).

In order to start using the evaluation environment the following steps are required:

Install the SPINFamily evaluation tool

Start the SPINFamily evaluation tool (by default it is in Start menu > All programs >

STMicroelectronics > SPINFamily Evaluation Tool).

Select the proper device when requested by the application.

Plug the STEVAL-PCC009V2 demonstration board to a free USB port.

Wait a few seconds for board initialization.

Connect the SPI_IN connector (black) of the demonstration board to the 10-pin

connector of the STEVAL-PCC009V2 board using the provided cable.

For connecting more devices to the same board, please consult the daisy chain

connection paragraph (Section 5: Daisy chaining on page 40).

Power-up the demonstration boards. The FLAG LED should turn on.

Click on the button with the USB symbol to connect the STEVAL-PCC009V2 board to

the PC and initialize the evaluation environment.

The application automatically identifies the number of demonstration boards

connected.

The evaluation environment is ready.

Before start working with the demonstration board, the device must be configured according

to the indications in Section 3: Device configuration.

Warning:

Important - the device configuration is mandatory. The

default configuration is not operative.
