Toothpick

General Setup

Insert the Toothpick in the evaluation board so that

the antenna overhangs the edge of the board.

There should be nothing inserted in the LinkMatik,

Stamp and BlueMatik sockets.

Remove any

existing links and then insert links over the

following configuration pins:

C5 – C6

(CCP4 to rotary switch)*

C7 – D7

(CCP3 to its LED)

C10– D10

(CCP2 to its LED)

E6 – F6

(TxD to its LED)

*Note: on one version of the board (TPDr5), the

“C5 - C6” is incorrectly labeled on the rear as

“C6 - D6”

If the RS232 port is to be used (e.g. DARC-I

tutorial) insert links over the following configuration

pins:

A3 – A4

(RS232 TxD to RxD pin)

B5 – B6

(RS232 RxD to TxD pin)

C4 – D4

(RS232 TxD to RxD pin)

In addition, if flow control is to be used (e.g.

DARC-I tutorial) insert links over the following

configuration pins. The ICD2 programming socket

cannot be used with these pins in place:

A8 – A9

(RS232 CTS to INT0 pin)

A10– B10

(RS232 CTS to INT0 pin)

B2 – B3

(RS232 RTS to INT1 pin)

B8 – B9

(RS232 RTS to INT1 pin)

If the RS232 port is not to be used (e.g. DARC-II

tutorial)

insert

a

link

over

the

following

configuration pin:

D4 – D5

(RxD to rotary switch)

If the I2C memory is to be used insert links over

the following configuration pins:

C3 – D3

(SDA to I2C memory)

D1 – D2

(SCL to I2C memory)

If the I2C memory is not to be used insert links

over the following configuration pins:

C1 – D1

(SCL to its LED)

C3 – C2

(SDA to its LED)

Toothpick Slave Tutorial

To follow the Toothpick Slave tutorial provided in

the Toothpick data sheet, remove any existing

links and then connect the links for RS232 (no flow

control) and I2C as follows:

A3 – A4

(RS232 TxD to RxD pin)

B5 – B6

(RS232 RxD to TxD pin)

C3 – D3

(SDA to I2C memory)

C4 – D4

(RS232 TxD to RxD pin)

C5 – C6

(CCP4 to rotary switch)

C7 – D7

(CCP3 to its LED)

C10– D10

(CCP2 to its LED)

D1 – D2

(SCL to I2C memory)

E6 – F6

(TxD to its LED)

Step 6 of the tutorial, adding an RS232 level

shifting circuit, is now complete and you may

simply connect your PC serial port to the DB9

socket on the evaluation board. The TxD LED will

glow more or less continually during the tutorial

because the TxD is usually in the high state.

You may the follow the tutorial exactly as in the

data sheet. When you have completed the tutorial

you might like to experiment with the I2C memory

as follows:

Type the command:

04010C01

to activate the I2C memory. This command a non-

volatile setting which only takes effect after a

device reset, so type the command

0200

to reset the Toothpick and wait for the greeting

message.

To store the values 0x05, 0x06, 0x07, 0x08 at

location 0x0100, type the command

090F10000105060708

To retrieve those same values, type the command

060E10000104

The retrieved values will be the last 8 characters of

the response.
