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))
