4 Setting of Baud Rate and COM Port

- Choose <Options><Select Port>

- Select the COM port to which your GEMINI-1

programmer is connected.

- Select the required target baud rate to

communicate with the target microcontroller.

The default is 9,600 baud which should work

reliably for most target systems.

If you wish to minimise the programming time, the baud rate may be increased. The

reliability of the programming operation depends on the target device and, to some

extent, the speed of the PC. Please refer to the ‘Microcontroller Timing Characteristics

Section’ on page 47 for further information.

5 Performing a ‘Signature Check’ of the target device

A quick check to make sure that the programmer is able to communicate with the target

device is to perform a ‘Signature Check’ operation.

- Select <Device><Check Signature>

-> The yellow ‘Active’ LED on the programmer should illuminate

-> The ‘Device Signature (ID) should be read from the target device and validated:

• PASS: Signature matches selected device

• FAIL: Incorrect signature - The wrong device may have been selected.

• Device not responding: Programmer could not communicate with target device.

(See Error Messages section)

6 Loading user code to the buffer area

To program the target system with real data, the buffer must first be loaded with the

user code.

- Select <File><Load to Buffer...>

The ‘Load to Buffer’ dialog as shown in Figure 16

- To load a file into the code area, click <Browse...> in the code section

- Select the required file (*.hex or *.bin)

- Click <Load>

- Click <Ok> to quit the ‘Load dialog box’.

Please note: The current TEMIC microcontrollers do not feature an EEPROM (Data)

Section, so the ‘Data’ dialogue has been greyed out.
