Programming/Debugging PC Connector (location 3)

• Location 3 refers to the programming/debugging PC connector. Via

this USB connector it is possible to either program the Matrix Module

or debug when developing custom firmware for the module.

• For programming the Matrix Module with custom firmware, the

suggested programming software tool is the “Chipcon SmartRF04

Flash Programmer”. This tool is available from TI/Chipcon. In

addition to the software tool a USB A-B cable is also required for

connection between the interface board and a PC.

• For debugging firmware that is developed using the IAR Embedded

Workbench for 8051, this USB connector can also be used. Again a

USB A-B cable is required. Additionally the jumpers J2 1-2, J8 1-2,

and J37 1-2, shown in location 2 of Figure 3-1 need to be installed.

Off Board Programming Header (location 4)

• Location 4 refers to the off board programming header. Via this

header it is possible to connect to an off board Matrix Module and

program it while in-circuit.

• A custom cable needs to be built that will allow the off board Matrix

Module to be connected to the interface board. Signals that are

provided on header J11 include “DEBUG_DATA”, “DEBUG_CLK”,

“RST”, “GND”, AND “VCC”.

• Refer to the “Programming/Debugging PC Connector” section above

for information on programming the Matrix Module.

Reset Button (location 5)

• Location 5 indicates the white button that provides ability to reset the

microprocessor on the Matrix module.

User Button (location 6)

• Location 6 indicates the white user button. Its main purpose is for

use with the ping pong range test (described in Section 2.2 above).

In order to use this button jumper J36 1-2 needs to be installed.

Headers for Access to All I/O Pins (location 7)

• Header to provide quick access to all of the I/O pins on the Matrix

Module.

LED Enable/Disable Header (location 8)

• To utilize LED’s the jumpers must be connected as shown in Figure

3-1. The jumpers may be removed to externally access pins P0_2,

P0_3, and P0_4 for input or output operation.
