Just modify it for your needs, and it’ll help with sending the commands from the Robosapien arduino library.


# change a hexadecimal string to decimal number and reverse
# check two different representations of the hexadecimal string
# negative values and zero are accepted
# tested with Python24 vegaseat 11oct2005
def dec2hex(n):
  """return the hexadecimal string representation of integer n"""
  return "%X" % n
def hex2dec(s):
  """return the integer value of a hexadecimal string s"""
  return int(s, 16)
print "dec2hex(255) =", dec2hex(255) # FF
print "hex2dec('FF') =", hex2dec('FF') # 255
print
print "hex(255) =", hex(255) # 0xff
print "hex2dec('0xff') =", hex2dec('0xff') # 255
