LED Lights and Switch Functions
Two LEDs and two push button switches are available on the MSP430F5529 LaunchPad development kit
to notify the user of different motor statuses and to control the operation of the motor. These switches are
configured in the reference software and preloaded with the following functions:
P1.1 switch (motor direction reversal) — This switch allows user to toggle the direction of motor spin
either to be clockwise or counterclockwise rotation.
P2.1 switch (fault clear switch) — This switch is configured to clear the fault status in SPI registers and
to restart the motor. When the user does not want automatic fault recovery when a fault occurs, it
can be turned off in the parameter setup file. In such cases, this button helps in restarting motor
after successful identification and mitigation of fault.
