The Kart module is a Summer School module for students at the end of the first year.

System Architecture

The kart is controlled by a smartPhone via BlueTooth.

A BlueTooth receiver on the kart control board communicates via an RS232 serial link with the control board FPGA.

BlueTooth communication

A BlueTooth communication transfers serial port data. A receiver chip creates the RS232 signals for the FPGA. The protocol defines how the registers are accessed.

The FPGA receives following controls:

  • the propulsion DC motor speed and direction
  • the steering stepper motor target angle and step period
  • two LEDs

The FPGA sends following information back:

Sensors

Board connectors

The FPGA board has following connections:

  • a 26 pin Header connector
  • a 9 pole DSub connector for RS232
  • the FPGA JTAG programming connector
  • the PIC RJ11 programming connector

Boards

For special designs, some boards have larger FPGAs:

  • Board 29 has a AGL125
  • Board 30 has a AGL250

Within the Actel Project manager, the settings of the FPGA have to be changed:

  • in Synplify: Implementation Options… -> Device -> Part<code>
  • in the place & route tool: <code>Tools -> Device Selection… -> Die<code>

To do

Use the register to set the rate at which the FPGA sends status to the remote control.

Set-up a hall sensor wheel rotation counter.
