VisSim Diagrams Available for TI Launchpad

A VisSim diagram suite and accompanying power point slide deck is now available for programming the $17 TI Launchpad. These diagrams now come standard with VisSim/Embedded Control Developer as downloaded from the VisSim web site. They come annotated with schematics and detailed directions for compiling, downloading and any hardware jumpering or switch settings required. In addition to ADC, GPIO, comparators, interrupts, PWM and I2C, the board also has a UART transceiver connected to the USB interface that enables a virtual COM port on the PC. This allows easy testing of embedded serial UART applications. The Launchpad, coupled with VisSim models and instructional materials makes an ideal teaching tool for model based embedded concepts. VisSim diagrams include:

  • ADC reading and display
  • ADC sync to PWM
  • Background threads
  • Digital scope for interactive PWM modulation viewing
  • DAC and comparator to turn PWM off and on based on external voltage.
  • GPIO rising/falling edge interrupt handler
  • GPIO Read of on-board push button with debouncing
  • I2C write to 8 way GPIO LED blink
  • I2C read of temperature sensor
  • I2C read/write of EEPROM
  • Interrupt latency check
  • LED blink
  • Multi-rate tasking
  • SPI master transmit triangle wave
  • SPI slave receive data to modulate PWM connected to LED
  • Trip zone use to disable PWM on GPIO12 low
  • UART packet transmit with checksum
  • UART packet decode with UML statechart
  • UART transmit string
