2.4.5 AVR Chip Programmer Setup

Using the Settings|Programmer menu command, you can select the type of the in-system programmer that is used, and the computer's port to which the programmer is connected. The current version of CodeVisionAVR supports the following in-system programmers:

•Kanda Systems STK200+ and STK300

•Atmel STK500 and AVRISP (serial connection)

•Atmel AVRISP MkII (USB connection)

•Atmel AVR Dragon (USB connection)

•Atmel JTAGICE MkII (USB connection)

•Atmel AVRProg (AVR910 application note)

•Dontronics DT006

•Vogel Elektronik VTEC-ISP

•Futurlec JRAVR

•MicroTronics ATCPU and Mega2000

The STK200+, STK300, DT006, VTEC-ISP, JRAVR, ATCPU and Mega2000 in-system programmers use the parallel printer port.

The following choices are available through the Printer Port radio group box:

•LPT1, at base address 378h;

•LPT2, at base address 278h;

•LPT3, at base address 3BCh.

The Delay Multiplier value can be increased in case of programming problems on very fast machines. Of course this will increase overall programming time.

The Atmega169 CKDIV8 Fuse Warning check box, if checked, will enable the generation of a warning that further low voltage serial programming will be impossible for the Atmega169 Engineering Samples, if the CKDIV8 fuse will be programmed to 0.

For usual Atmega169 chips this check box must be left unchecked.

CodeVisionAVR

The STK500, AVRISP and AVRProg programmers use the RS232C serial communication port, which can be specified using the Communication Port list box.

The Atmel AVRISP MkII, AVR Dragon and JTAGICE MkII use the USB connection for communication with the PC.

Usage of this programmer requires the Atmel’s AVR Studio V4.13 or later software to be installed on the PC.

Changes can be saved, respectively canceled, using the OK, respectively Cancel buttons.

2.4.6 Serial Communication Terminal Setup

The serial communication Terminal is configured using the Settings|Terminal menu command.

In the Terminal Setup window you can select the:

•computer's communication port used by the Terminal: COM1 to COM6;

•Baud rate used for communication: 110 to 115200;

•number of data bits used in reception and transmission: 5 to 8;

•number of stop bits used in reception and transmission: 1, 1.5 or 2;

•parity used in reception and transmission: None, Odd, Even, Mark or Space;

•type of emulated terminal: TTY, VT52 or VT100;

•type of handshaking used in communication: None, Hardware (CTS or DTR) or Software (XON/XOFF);

•possibility to append LF characters after CR characters on reception and transmission;

•enabling or disabling the echoing of the transmitted characters

•number of character Rows and Columns in the Terminal window

•Font type used for displaying characters in the Terminal window.

Changes can be saved, respectively canceled, using the OK, respectively Cancel buttons.
