  1. Software Design Narrative Team 1 Hang Xie

  2. Software Design Considerations • Utilization of integrated peripherals pwm, uart, i2c, atd • Computer vision library OpenCV or SimpleCV

  3. Software development status • MicroController part: PWM done UART transmitting done UART receive part not done ATD not done I2C not done • Intelligent part UART done Simple CV not done Atom Motherboard

  4. Software development status • Register initializations required PWM UART I/O OCxCON1 U1BRG TRISB OCxCON2 U1TXIPx OCxR U1STA OCxRS MODE PSS register

  5. Flow chart for micro ( using raspberry pi)

  6. Flow chart for micro (Atom)

  7. State machine, polling loop

  8. Software Design Considerations • Port names/addresses: Programming port: RP1, RP0,VSS,VDD,MCLR PWM1: RP6 PWM2: RP7 PWM3: RP8 PWM4: RP9 PWM5: RP14 PWM6: RP29 UART_RX: RP11 UART_TX:RP12 I2C_SDA : RP10 I2C_SCL: RP17 I/O: RP3, RP4, RP30, RP16, RP23

  9. Software Design Narrative Shareware sources • pySerial : Serial(port,9600), flushInput(), read(), write() • Raspbian • SimpleCV • OpenCV My own modules • pwm_init( ) • pwm_con( ) • uart_init( ) • uart_get( ) • uart_put( ) • atd_init( ) • Init_all( )

  10. Hierarchical arrangement of the various code module

  11. QUESTIONS
