new uBoot commands

  • led in[it] - setup GPIOs
  • led ge[t] - get button status
  • led se[t] hh - set LEDs to lower 4 bit
  • led se[t] - increment last state, i.e. make LEDs count
  • led mi[rror] - read button status and mirror to LEDs until a key is pressed
  • led bl[ink] - blink LEDs

  • lcm in[it] - initialize subsystem (DSS, GPIOs etc.)

  • lcm ba[cklight] dd - set backlight level (0..255)
  • lcm po[wer] dd - set power level (0..2)
  • lcm on - set lcm on
  • lcm of[f] - set lcm off

  • tsc init - initialize/enable TSC2007 through I2C2

  • tsc get - read current ADC values (incl. internal temp and AUX/photosensor)
  • tsc lo[op] - read x/y coordinates
  • tsc ch[oose] cols rows - defines receptive fields and waits until touch is pressed
  • tsc choice x - check if choice was x (1..rows*cols)

To be Done:

  • gps on | of[f] - control GPS receiver (and initialize UART)
  • gps re[ad] - read GPS NMEA from UART until a key is pressed
