Motor M1 Commands
Commands 0x8C – 0x8F apply to motor M1. In 8-bit mode, commands 0x8D and 0x8F will set the motor speed to
128+motor speed; in 7-bit mode, command 0x8D is identical to command 0x8C and command 0x8F is identical
to command 0x8E.
For example, in 8-bit mode, the command packet 0x8C, 0x7F will set motor M1 speed to 127 out of a maximum
of 255, which will result in the motor’s turning at half speed. The command packet 0x8D, 0x7F will set motor
M1 speed to 127+128 = 255, which will result in the motor’s turning at full speed. In 7-bit mode, both commands
will set motor M1 speed to 127 out of a maximum of 127, which will result in the motor’s turning at full speed.
