This demo shows how to set up a USB connection between the PC and the FLEX board. The aim is to control the dsPIC LED and the PIC18 LED system from the host PC. The dsPIC LED is controlled by the SPI communication with the PIC18.
The application is divided into three parts: - In the first part a brief description of the USB set-up is provided. The aim is to give a brief overview of the USB protocol.
- The second part concerns the dsPIC side with the use of the SPI connection with the PIC18.
- The third part concerns the PC side application. You can download a simple application under Windows (XP or Vista) to communicate with FLEX in order to switch on and off both LEDs of dsPIC and PIC18.
Future application notes will develop the USB connection up to the control of the dsPIC functions through the host PC with a Linux application. |

This demo shows how to set up a procedure for identification of a DC Motor with permanent magnets aimed at digital torque control.
The application is divided into two parts: - In the first part the dsPIC implements a simultaneous sampling of voltage and current and sends the data via serial bus to a remote PC (sampling time equal to approximately 4e-5 sec, number of samples 12800 * 2,signal voltage type PRBS)
- In the second part the PI controller, designed on the model identified, is used to control the current (directly) and the torque (indirectly) with appropriate characteristics of strength (sampling time of 6.4e-5 sec)
On the PC side, the data are processed with a specific software for the system identification. The applied methods are: - Subspaces Method (with generic I/O data)
- PEM method (to refine the model)
- Residual Analysis (to validate the model)

 The demo board The demo acquires angle and distance from a compass and a ultrasound receiver, sending them to a remote system using an XBee module connected through UART. On the PC side, then, a GTK graphical application (not available for download) displays the data in a polar plot. Board schematics, PCB and software available as a template under ERIKA Enterprise. |
