KamPROG for AVR

__jzXpdf__

Introdcution

KamPROG for AVR is development/production programmer for Atmel AVR microcontrollers. It can be controlled by KamProg application, Bascom AVR and AVR Studio. Programmer is connected to PC USB port. KamPROG works with AVR microcontrollers that can be connected through 10-pins IDC header (Atmel standard).

Features

• Programmer for ISP-enabled AVR microcontrollers
• 10-pins IDC output header, Atmel standard pinout (Fig. 1)
• Power supply from USB port
• Operates with KamPROG application, Atmel AVR Studio and Bascom AVR
• Windows XP, Windows Vista compatible

Installation

KamPROG for AVR does not require drivers, you only need to download and install KamPROG software (http://www.kamami.com/?content=kamprogavr). During installation you have to decide, whether you want to in- stall AVR Studio Plug-in (Fig. 2). Bascom AVR (v. 1.11.9.3 and newer) supports KamPROG for AVR.

Software

On the figure 3 you can see programmer’s application window.

Microcontroller tab

On this tab you can find list of supported microcontrollers. You can choose programmed device on the list or identify it using its signature bytes (Identify microcontroller button). If you check Auto-identify checkbox then device will be identified everytime you open this tab.

Memory programming tab

To erase microcontroller’s Flash memory, EEPROM memory (if EESAVE is not set), lock bits (LB, BLB0, BLB1) press Chip erase. To write Flash memory enter hex file name, press Write button in Flash section. You can also use two additional options: Erase chip before Flash programming and Verify written data. You can also verify written data by pressing Verify button and read microcontroller’s Flash memory conent into hex file (Read button). EEPROM section works similar (Erase chip before Flash programming and Verify' written' data options are not available for EEPROM).

Fuse bits and Lock bits tabs

Here you can set fuse bits and lock bits values.

Be careful while changing fuse bits values. Some combinations can make microcontroller not accessible using SPI! For more informations see microcontroller’s documentation.

Programmer setup tab

Here you can set ISP frequency and read programmers firmware version. Make sure that ISP frequency is less than microcontroller frequency divided by 4.

AVR Studio 4

If you selected KamPROG for Atmel AVR Studio plug-in option during installation, then you can use KamPROG in Atmel AVR Studio 4. If there is no Kamami AVR programmer item in Tools menu and there is no Kamami toolbar, then open Plug-in Manager (Tools>Plug-in Manager) and check Kamami_AVR_programmer in the list, restart AVR Studio. Now you can open programmer’s application (Tools>Kamami AVR programmer>Connect) and write Flash memory (Tools>Kamami AVR programmer>Write Flash), both operations can be done using toolbar.

Write Flash works only when project’s output hex file has the same name as project file!

Command line

You can also use command line tool – KamPROGAVRc.exe – to work with KamPROG AVR. First you have to go to KamPROG AVR folder (default path is C:\Program Files\KamPROGAVR), then type in KamPROGAVRc and press Enter to display help.

Examples

• Performing chip erase of autodetected device:

KamPROGAVRc -d -r -s 2

-d - chip autodetection

-r - chip erase

-s 2 - set SPI frequency to 50kHz (omitting this parameter sets frequency to 100kHz)

• Reading ATmega8 fuse bits

KamPROGAVRc -c ATmega8 -B

-c ATmega8 - connected device is ATmega8

-B - read fuse bits

• Writing led.hex into autodetected device’s Flash memory:

KamPROGAVRc -d -f led.hex

-f led.hex – write led.hex into device’s Flash memory
