Getting Started with the Point Runner¶
The Point Runner requires an Intel Edison Compute module to function. The Edison may be either mounted directly on the Point Runner board, or on a seperate breakout board connected via USB.
- If the Edison is to be mounted directly on the Point Runner, it should be clipped into the 70-pin socket in the centre of the Point Runner board over the Tektyte logo. The switch labelled “FPGA Source” should be set to the “EDISON” position.
- Alternatively, the Edison may be attached to another breakout board with USB on-the-go capabilities (such as the Arduino Breakout Board or the Tektyte Edi-Expand). The USB OTG port on the breakout board should be attached to the “USB” micro-usb port on the Point Runner and the switch labelled “FPGA Source” should be set to the “USB” position.
The Point Runner board requires an external 5V DC power supply connected to the “DC IN” port to power the Edison and onboard FPGA.
The LED strips and servo motors s be connected to a Tektyte Hexa LED Power Injector board via the green three wire terminals, and an appropriate high-current power supply should be connected to the Injector board. The Point Runner power supply is isolated from the Injector board power so voltages other than 5V may be used if the LED strip or servo motors are compatible. The Hexa LED Power Injector boards should be connected to the 16-pin headers on the edges on the Point Runner board.
Power up the Point Runner and connect to the Intel Edison terminal (either using the “CONSOLE” USB port or using WiFi and SSH). The Intel Edison will need to be connected to a WiFi network to transfer the required software from a PC; use “configure_edison –wifi” to set up the WiFi connection and “wpa_cli status” to determine the Edion’s IP address.
Use a program such as WinSCP to transfer the PointRunnerSetup folder (available from the Tektyte website) onto the Edison. Run setup.sh to install all required libraries as well as the example programs.
Testing the Point Runner¶
The simplest way to verify that the Point Runner is properly set up and configured is to use one of the included test programs. First, power up the board and connect to the Intel Edison terminal (either using the “CONSOLE” USB port or using WiFi and SSH).
- To test the board with LED strip attached, run the included program named “anim”. This should generate a green line which travels back and forth along the strip.
- No program has been written to test servo motors yet.
