3.2.1.1 Microcontroller and Peripherals

The Freescale 8-bit MC9S08LG32 high-performance microcontroller unit (MCU) controls the entire

application and is the heart of the main board. The MCU (U1) uses enhanced central processor unit and

embedded peripheral modules.

The application occupies the following peripheral modules:

• One 16-bit timer/PWM interface module (TPM2), 2 channels in the input capture mode and 1

channel in PWM mode

• One 16-bit timer/PWM interface module (TPM1) in the PWM mode

• Liquid crystal display driver (LCD)

• General-purpose input/output pins (I/O)

• Keyboard interrupts (KBI)

• 12-bit successive approximation analog-to-digital converter (ADC)

For pin muxing of MC9S08LG32 80-pin LQFP and its use in this design, refer to Appendix C,

“MC9S08LG32 Pin Connections on Cluster Reference Design Board.”

The MCU uses one channel (ADC4) of the ADC to perform fuel-level sensing, one channel (ADC5) for

temperature sensing, and one channel (ADC11) for gear-number sensing. The resolution of the ADC is

12 bits. The ADC measures the corresponding voltage provided at its channel input through the header

(J3).

The MCU can drive a maximum of 41 front planes and 4 back planes of an LCD display. The application

uses an LCD display with 28 front planes and 4 back planes. Because of the 4 back planes, a 1/4 duty of

the output waveform is set. When the LCD driver is enabled, the back plane waveforms for the selected

duty are driven out through the back plane pins. The back plane waveforms are periodic. The speed in

km/h, odometer, trip A, and trip B data in km, mileage in kmpl, time in hour and minute, HVAC indicators,

fuel levels, check oil, service mode, temperature, engine hot/cold, battery level, etc. are displayed on the

32-pin LCD glass (U5).

The MCU uses one channel of TPM (TPM2CH3) for speed input and one channel of TPM (TPM2CH5)

for rpm input in input capture mode and one channel of TPM (TPM2CH0) in edge-aligned PWM mode to

drive the piezoelectric buzzer for left/right turn audio indication through one channel of 74AC125 tri-state

quad buffer.

Architecture

Freescale Semiconductor 17

For speed and rpm sensor inputs, the appropriate pulse shaping circuit has been added.

For the stepper motor application, the MCU drives the stepper motor through a 74AC125 Tri-stated Quad

Buffer driver using two channels of TPM (TPM1CH0 and TPM1CH1) in edge-aligned PWM mode along

with two GPIOs (PTA4 and PTA5).

The KBI provides eight independently maskable external interrupts. The KBI pins are shared with

standard I/O pins. The application uses all eight of them:

• KBI7 for SW1

• KBI1 for SW2

• KBI2 for left turn input

• KBI0 for right turn input

• KBI3 for fog light input

• KBI4 for head light input

• KBI5 for touch sensor input

• KBI6 for side stand input

The MCU drives the following GPIOs for LED indicators through two 74AC125 ICs:

• PTC4 for head light indication red LED

• PTA0 for side stand indication red LED

• PTA2 for fog light indication red LED

• PTA1 for neutral gear indication green LED

• PTG2 for right turn indication green LED

• PTG3 for left turn indication green LED

The MCU also controls the backlighting control of the cluster through one of its GPIO PTB0 and monitors

the check oil at PTB1.

The MCU is interfaced to a touch sensor on the interface board using I2C interface. The pin PTB1 is

connected to the

ATTN pin of touch sensor, MPR084, for the MCU to establish connection. For more

details on touch sensor application, refer to

Appendix F, “Enabling Touch Sensor Application.”

The standard 6-pin BDM interface along with USB to BDM wiggler is used to communicate with the PC

for reprogramming and debugging the application.

The emulated EEPROM is used to store the trip and odometer data.

3.2.1.2 Power Supply

The cluster is turned on from the 12-V DC. A simple linear voltage regulator 33269DT-5 is used to provide

a 5-V power supply for the cluster devices.

The schematic of the power supply can be seen in Figure 3-5.

It is necessary to save odometer and trip meter data if the power supply from the battery is switched off.

The resistor dividers, R1 and R2, monitor the battery power supply and generate an interrupt signal in

case a power off occurs. The capacitors C5, C6, and C9 hold a voltage long enough for the microcontroller

to perform an interrupt service routine to save the data. C9 can be replaced by a higher value for better

discharge time.

3.2.2 LG32 Cluster Reference Design Interface Board

This board consists of the MC9S08QD2 MCU for simulating speed and rpm sensors, potentiometer, and

switches for simulating other analog and digital sensors.

Figure 3-6, Figure 3-7, and Figure 3-8 provides

the layouts of LG32 cluster reference design interface board, top layer, and bottom layer.

Figure 3-6. LG32 Cluster Reference Design Interface Board

Figure 3-7. LG32 Cluster Reference Design Interface Board Layout Top Layer

Figure 3-8. LG32 Cluster Reference Design Interface Board Layout Bottom Layer

The interface board simulates various analog and digital sensor inputs to the main board. The interface

board consists of a MC9S08QD2 MCU that accepts varying analog input through the potentiometers and

generates two PWM signals at its output. The frequency of these PWM signals depends on the ADC input

through the potentiometer and these PWM signals work as speed and rpm input to the reference design

board. Three additional potentiometers are directly connected to the reference design board to simulate
