motor mind b enhanced help

ccc11223

i just got a mmbe, and have never used the serin and serout commands before. i understand the concept of duty cycle, but all of the $## is confusing me. i simply need to make a dc motor run at full speed forward, and full speed backward. if someone could help me out by giving some example code it would be greatly appreciated.

Each SEROUT to the MMBE must start with a $55.
A $55 is ASCII for a 'U'.
HEX isn't necessary.

' {$STAMP BS2}
' {$PBASIC 2.5}


' motormindexp.bs2

up_down:
  SEROUT 0, 396, ("U", 3, 255)   ' full on
  PAUSE 2500

  SEROUT 0, 396, ("U", 3, 128)   ' 1/2spd
  PAUSE 2500

  SEROUT 0, 396, ("U", 3, 0)     ' lowest
  PAUSE 500

  SEROUT 0, 396, ("U", 3, 1)     ' change dir
  SEROUT 0, 396, ("U", 3, 64)    ' 1/4spd
  SEROUT 0, 396, ("U", 3, 0)     ' lowest
  PAUSE 500
  SEROUT 0, 396, ("U", 3, 1)     ' change dir

  GOTO up_down
