  2. Main Loop • Interrupt Driven • Two Microcontrollers • Base Station • Remote Station Software

  3. Base Station Routines

  4. Power On • Initialize • Turn on Interrupts • Main Loop • PS2 Controller • On Screen Display • Power • Transceiver Flowbullets (Base)

  5. Remote Station Routines

  6. Power On • Initialize • Turn on Interrupts • Main Loop • Compass • Servos • Motor Driver • Power • Transceiver Flowbullets (Remote)

  7. // do some initializations spi_isr(VECTOR, ipl3) { int Data; // Read SPI data buffer Data = SPI1BUF; /* do stuff */ // clear the SPI1 interrupt flags IFS0CLR = 0x03800000; } SPI ISR

  8. // do some initializations iic_isr(VECTOR, ipl3) { case Start /* stuff */ ACK NACK Stop // clear interrupts IIC0CLR = 0x0440 } I2C ISR

  9. // do some initializations pwm1_isr(OC1_VECTOR, ipl3) { /* do stuff */ // clear the OC1 interrupt flags IFS0CLR = 0x0040; } PWM ISR
