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:
