LIN Remote Control
LIN properties
Returns the on-going commutation type (use definitions MC_COM_HS or MC_COM_LS or
MC_COM_HLS).
The demonstration software for the ATA6833/ATA6834-DK includes a LIN remote control
function. This application represents a LIN slave node based on LIN1.3. It is possible to con-
trol the motor by several commands.
When the application receives a valid command then the display information will be updated
accordingly. Command behavior is similar to a switched button. For example, sending the
command LIN_MOTOR_START_STOP at the first time, the motor will start. At the second
time the motor will be stopped.

BLDC Motor Control Kit with ATA6833/ATA6834
• LIN1.3, 19200 baud rate
• LIN ID 0x03 is implemented as TX message handler and returns motor speed when a
• LIN ID 0x02 is RX message handler and expects header+data frame from LIN master. The
• Message length of LIN ID 0x02 and 0x03 is 2 bytes
header frame is received from LIN master
data frame has to contain motor control commands like it is shown in the list below.
