DIU Notes

• PIC32MX360F (U6) running at 8MHz from an external oscillator
• 7-segment clock:
  • PIC talks to STP08DP05 (U9) shift register through (LED0, LED1, LED2, LED3)
  • shift register only drives on digit at a time
  • PIC multiplexes four digits on 7-segment clock with (LED4, LED5, LED6, LED7)
• Viper serial connections through J19 (20x2 header)
• Main power connector through J21
  • (TX3,RX3) goes to PIU serial line
  • (Vault0,Vault1) lines control vault motor through U12
  • (DSR4,RTS4,CTS4) control GPRS modem
  • (VIN) to GPRS and PIU
• (J9) GPS connector
  • Takes in (protected) bus power (VIN)
  • Uses RS232 levels and feeds into (U8) - [R2IN,T2OUT]
• GPS level converter (U8) SP3232EEN
  • Takes in GPS levels to convert to PIC (GPSTTLRX, GPSTTLTX)
  • Takes in PIC levels and converts to Viper serial levels (VIPTTLRX, VIPTTLTX) -> (RX2, TX2)
• Debug serial line (J22) to get access to (RX1,TX1) on viper
• Connector (J26) to potentiometers for sound, screen brightness and audio level
  • (LEDADJ0,LEDADJ1) for 7-segment clock adjustment which feeds into (U9) to do brightness control
  • (AN11) for LCD brightness control which feeds into PIC (that then pwm controls (BLAdj))
