  18. Computer Peripherals Computer Peripherals/Interfaces • A computer peripheral is an electronic device connected to the CPU via a computer interface. • Printer • LCD • Disk • Real-time Clock • A computer interface is an electronic device that connects the CPU with a computer peripheral. • Serial Port • Parallel Port • A/D or D/A Convertor • Voltage Amplifier • JTAG or Spy-by-wire RBX430

  19. Interfaces / Peripherals RBX430-1 Interfaces / Peripherals • Timers A/B • PWM LEDs • PWM Servos • PWM Speaker • USCI A/B • USART – Universal Serial Asynchronous Rx/Tx • SPI – Serial Peripheral Interface • IrDA – Infrared Data • i2c – Inter-Integrated Circuit • FRAM (8k) • 3 Axis Accelerometer • RTC (w/battery backup) • Temperature Sensor • 8-bit I/O Parallel Port • Watchdog+ • A/D Converter (ADC10) • Potentiometers (Left & Right) • Thermistor (10k ) • Operational Amps (OA0-3) • Ports (P1-P4) • LEDs • Switches • LCD • LCD Backlight • Servos • Speaker • Power Module • Digitally Controlled Oscillator (DCO) • Very Low Frequency Oscillator (VLO) • 4.5v AC Line Power • 4.5v DC Battery Power RBX430

  20. Peripheral Interface ADC10 High-performance 10-bit analog-to-digital conversions • More than 200k samples/sec • Programmable sample & hold • Initiation by software or Timer_A • 8 external input channels • Selectable voltage reference (1.5v or 2.5v) • Internal storage RBX430

  21. Port1 Port3 Port2 Port4 Function Select Register PxSEL yes yes Interrupt Edge Select Register PxIES yes no Interrupt Enable Register PxIE yes no Interrupt Flag Register PxIFG yes no Direction Register PxDIR yes yes Output Register PxOUT yes yes Input Register PxIN yes yes 7 6 5 4 3 2 1 0 Peripheral Interface Ports - Digital I/O Independently programmable individual I/Os • 4 ports (P1 – P4) • Each has 8 I/O pins • Each pin can be configured as input or output • P1 and P2 pins can be configured to assert an interrupt request RBX430

  22. Peripheral Interface USART - Serial Port The Universal Synchronous/Asynchronous Receive/Transmit peripheral interface supports two serial modes with one hardware module • UART • SPI (Synchronous Peripheral Interface) • IrDA • I2C (Inter-Integrated Circuit) • Double-buffered • Baud-rate generator RBX430

  23. Peripheral Interface i2c – Inter-Integrated Circuit • Inter-Integrated Circuit • 2-wire serial interface (Serial data SDA, Serial clock SCL) • master/slave (slaves have unique 7-bit address) • 100-400 kbit/sec (relatively slow) • Master provides clock Slave acknowledgment Stop condition Start condition Write SDA RBX430 SDA stable Read SDA SDA may change

  24. Peripherals A computer peripheralis a auxiliary device that connects to and works with a computer. A peripheralexpands the computer's capabilities but does not form part of the core computer architecture.

  25. Peripheral Timer_A/B Timer_A/B are 16-bit timer/counters with three capture/compare registers • Capture external signals • Compare PWM mode • SCCI latch for asynchronous communication RBX430

  26. Peripheral Watchdog Timer WDT module performs a controlled system restart after a software problem occurs • Can serve as an interval timer (generates interrupts) • WDT Control register is password protected • Note: Powers-up active RBX430

  27. Peripheral FRAM (Ferrite RAM) • Ferro-electric Non-volatile RAM • i2c serial bus, address 0x50 • 8192 x 8 bits • 100 times faster than flash using half the power • Ultra-fast writes • Unlimited R/W cycles (1014 = 100 Trillion) • Immune to magnetic fields – no iron! • Addresses 21st century macro trends • Wireless • Low Power • Security • Endurance RBX430
