Background
BeagleBone PRUSS
The BeagleBone is a low-cost, high-performance embedded platform for hobbyists and other uses. It is based upon a TI AM335x 1GHz ARM® Cortex-A8. Features (from the product website) include:
Processor: AM335x 1GHz ARM® Cortex-A8
- 512MB DDR3 RAM
- 2GB 8-bit eMMC on-board flash storage
- 3D graphics accelerator
- NEON floating-point accelerator
- 2x PRU 32-bit microcontrollers
Connectivity
- USB client for power & communications
- USB host
- Ethernet
- HDMI
- 2x 46 pin headers
The board comes pre-loaded with and Ångström Linux distirubtion and many other options can be considered for development and operating the device. It is a very powerful device well suited for a number of soft real-time applications.
Procedure
The goal is to have a task that every 300 ms checks the distance of the IR Rangefinder and change the servo's position accordingly.
- Open the lab stationary using CodeWarrior located in:
LAB04/Micrium/Software/EvalBoards/Freescale/MC9S12DG256B/WytecDragon12/Metrowerks/Paged/ OS-Probe-LCD/OS-Probe-LCD.mcp
- Add a task that every 300 ms calls ir_range(ATD0DR0)
- Connect the VCC and ground wires of Servo and IR Range Finder. Make sure you have +5 volts and have a common ground between the microprocessor and your power supply.
- Connect PP7 pin to servo's input signal and PAD04 pin to R Range Finder output signal.
- Double check your circuitry with your TA before powering up anything.
- Recompile the project and transfer the binaries to Dragon12 board.
