4.2 ON-BOARD INTERFACES:

4.2.1 Slide Switch (SW1):

The slide switch SW1 is used for programming the flash memory. When this switch

is in PROG mode on the board the pin /RST/NMI (Pin-94 of U1) goes low forcing the

on-chip boot loader execution. When the switch SW1 is in RUN mode the pin /RST/NMI

is released high through a resistor and user application will be executed.

4.2.2 Serial Interface:

The board has a USB B-TYPE serial communication port. The Tx and Rx signals

that appear on the USB B-TYPE connector CN17. Use a standard USB TO B-TYPE cable

to connect the board to the computer's use USB port connector. The controller device

MSP430F449 (U1) supplies serial I/O data at TTL levels to the FT232R device (U15).

4.2.4 Six Digit Multiplexed 7-Segment Displays:

There are six multiplexed 7-segment display units (U16, U17, U18, U19,

U20 and U21) on the board. Each display has 8-inputs SEG-A (Pin-7), SEG-B (Pin-6),

SEG-C (Pin-4), SEG-D (Pin-2), SEG-E (Pin-1), SEG-F (Pin-9), SEG-G (Pin-10) and SEG-

H (Pin-5) and the remaining pins pin-3 & pin-8 are Common Cathode CC. These

segments are common cathode type hence active high devices. The port lines P2.4 to

P2.7 are used to select one of the four digits as shown in the table below. These signals

P2.4 to P2.7 are used as inputs to the 74LS145 (U3) and the output lines of the

decoder are used as enable lines for six 7-segment displays. The port lines P3.0 to P3.7

are used as segment lines for the six digits through the 74HCT244 buffer (U4).

0 1 0 1 U21

4.2.5 Keypad (4 Rows X 4 Columns):

The switches 0 to F are organized as 4 rows X 4 columns matrix. One end of all

the switches are connected to port lines P2.4 P2.7, which are configured as columns.

The other end of the matrix is connected to the port lines P2.0 P2.3 which are

configured as rows. The interface diagram for keypad is shown below.

Operation: Initially take one column line to logic HIGH, then check for each row. If

first row is at logic '0' and other rows are at logic '1' then save the read data and

compare with the look-up table. Similarly repeat the procedure for all the columns

4.2.6 Temperature Sensor (LM335 D14) & 12-Bit ADC:

The channel-0 of the 8-channel 8-bit ADC device U9 (ADC0809) is connected to

the preset voltage (POT R33) varying from 0V to 4.5V. The Channel-1 is connected to

the Relay mate to feed the analog channel externally (Before feeding any channel make

sure it not more than 5V). The temperature sensor device used in this interfacing block

is LM335 (D11). The sensor device is connected to the Channel 2 (CH2) of the

ADC0809 (U9). The port lines PX.1, PX.2 & PX.3 are used for Channel selection. The

circuit diagram for ADC interface is as shown in next page.

4.2.7 High Current Output Lines and Relay Interface:

Any of the 3 ports can be used for High Current applications where a stepper

motor, a Dc motor are interfaced through the high current driver ULN2803. These lines

will have high current (max 300 mA) with low voltage level of 0.7V.

The Stepper motor can be interfaced to the board by connecting it to the

Powermate PM1. The rotating direction of the stepper motor can be changed.

The DC Motor can also be interfaced to the board by connecting it to the Relay

mate RM4. The direction of the rotation can be changed through software.



4.2.8 ELEVATOR:

An elevator presents typical problem to logic designers. A number of situations

like the occurrence of simultaneous requests, the assignment of priorities & the logging

of requests are frequently encountered.

The control & operation of an elevator within a building, having three floors is

simulated by this interface. A key & corresponding RED LED indicator serves as a

request button & request status indicator. A row of LEDs indicate the position of the

elevator within the shaft. The Green LED when lit indicates that the elevator is at a

floor. The servicing of a request can be indicated by clearing the request (turning OFF

the request indicator flip-flop).

A four line to 10 line decoder is used to specify the location of the elevator

within the shaft. When the four inputs to the decoder are sequenced through the binary

codes, corresponding to 0 to 9 with a time interval between transitions, the elevator is

seen to move. Two dual D flip-flops are used to sense requests & output the status. A

request is cleared through the clear inputs of the flip-flops.

The elevator starts at the ground floor & moves up to the top. The requests are

sensed each time the lift position is changed. Once the elevator has moved to the top

all the requests are cleared.

4.2.9 DAC (DAC0800)

DAC0800 is used to convert the digital data into analog signals. Digital data from

any port is given to DAC input. Amplitude of output waveform can be varied by varying

the pot R40 that is by varying the reference voltage of DAC0800.

4.2.10 SPI ADC:

12 Bit SPI ADC is directly interfaced to the controller through the controller port

lines P4.2(CS), P4.3(MOSI),P4.4(MISI) and P4.5(UCLK). Using the connector CN15 the

lines are interfaced with the controller.

4.3 JUMPER DESCRIPTION:

There are 4 jumpers provided on the Controller board, the description and their

significance are given below.

Jumper Significance

JP1 JTAG connects the VCC

JP2 JTAG connects the VCC

JP3 For to monitor DVCC1 voltage

observed at the test point TP10. Similarly the clock signals SMCLK and MCLK can be

observed at test point TP9 and TP11 respectively.



CHAPTER 7

TROUBLE SHOOTING

If any trouble is faced then refer to the schematic and resolve the problem

according to the following suggestions.

GENERAL PROBLEM: In case of any problem check out the clock signals ACLK,

SMCLK & MCLK at the port lines P1.5, P1.4 and P1.1 respectively. The clock signal ACLK

= 32768 Hz, can be observed at the pin 4 of the connector CN6. Similarly the clock

signals SMCLK = MCLK = 1048550 Hz can be observed at the pin 3 and TP11

respectively. If the clock signals are not accordingly then check out the microcontroller.

POWER FAILURE: If power LED L1 is not glowing then, check out the LED. If LED is in

good condition then it means the power is not supplied to the MSP430 board. Check out

the +5V incoming power at the pin 9 of connector CN2. If +5V is not supplied then

replace the +5V power supply unit with the one which is working good.

If then also power is not supplied then check out the input of the regulator U2 on board.

If +5V is measured at the input pin-3 of the regulator U2 and 3.3V is not obtained at the

output pin-2 of the U2 then replace the regulator with the one which is working good. If

then also power is not supplied to the board then refer to the schematic and checkout all

the related tracks on the board.

DOWNLOADING PROBLEM: If there is any problem in downloading the program then

check out the followings

1. Check out the proper connections as per the downloading details provided.

2. Check whether proper target device is selected in the MSPFET utility.
