1Purpose
These labs will show the various MC9S08PT60 demo examples on the Tower System module. LAB1 to
LAB6 are integrated in a single project TWR-S08PT60_lab, while others are independent. You can switch
from LAB1 to LAB6 via the keyboard interface SW2 and/or SW3. The demo examples include TSI with low
power, potentiometer, accelerometer, IR, UART loop demo, and SPI demo. You can also play with the
standalone Flash & EEPROM lab (TWR-S08PT60_flash_lab), as well as the BLDC demo (TWR-
S08PT60_bldc_demo).

11 Lab8—BLDCdemo
This lab will demonstrate how to implement a simple BLDC motor control with the FlexTimer module FTM2
which is designed to support motor control, digital power conversion and other applications that require
PWM signals. It will use touch pad 0 and touch pad 1 to control the motor speed and the rotation direction.
The start and stop of the motor’s spin are controlled via the keyboard interface SW2. This lab requires a
special connection from the general purpose TWRPI connectors on the board to the 40-pin daughter card
connector P1 on APMOTOR56F800E which can be ordered from the Freescale website:
www.freescale.com/tower
The following steps show how to work with this demo:
1. Download S08PT60_BLDC_demo code to the board via OSBDM.
2. Disconnect the USB cable from PC to turn off power to the board.
3. Connect general purpose TWRPI connector of the board to P1 of APMOTOR56F800E as below:

5. Press and release SW2 which sets motor to be ready state.
6. Touch pad 0, the motor starts to run in clockwise direction. Repeat touching pad 0, the motor speed
will be increased up to the maximum. Both D7 and D8 flash to reflect the signals from the hall
sensor.
