QCX CW Alıcı/Verici USBAsp Yardımıyla Firmware Yükseltme (Windows)

QCX is a feature-packed, high performance, single-band 5W CW transceiver kit, with WSPR beacon and built-in alignment/test equipment. Available for 80, 60, 40, 30, 20 or 17m bands. It has rotary encoder synthesized tuning, VFO A/B/Split, Iambic keyer, CW decoder, and more… Detailed info can be found at https://www.qrp-labs.com

The QCX kit includes a 2 x 3-pin standard AVR header for In-Circuit-Programming on the board and uses ATmega328 chip. Time to time QRP Labs provides firmware upgrades. Latest updated firmware is 1.09a and existing QCX units can be upgraded. You can check the latest firmware announcements and history from https://www.qrp-labs.com/qcx/qcxfirmware.html

If you don’t want to wait you can upgrade your QCX easily by yourself. This guide is for Windows users but if you’re using MacOS computer click here.

For Linux, terminal command below can be used in Linux computers after downloading avrdude tool.

There is an alternative upgrade guide using Arduino Uno. CLICK HERE for a tutorial written by Simon VK3ELH on how to use an Arduino UNO and the AVRDudes to update your QCX firmware.

Requirements

• Software
  • avrdude (click here to download, includes OCX latest firmware)
  • latest OCX firmware (included in avrdude pack or get it from https://www.qrp-labs.com/qcx/qcxfirmware.html)
  • usbASP device Windows driver (Click here do download)
• Hardware
  • USBasp device with 10 pin to 6pin adaptor (Arduino device also can be used but requires some more experience. See tutorial written by Simon VK3ELH)

(USBasp device can be used without 6 pin adaptor but you should match the pins on the cable. Its cheap, I suggest getting the full kit as seen in above picture.)

Firmware Upgrade Procedure

Step 1: Install USBasp driver

Extract the USBaspWinDriver.zip file and run InstallDriver.exe

Step 2: Extract “avrdude” zip file

Extract the avrdude-6.4.zip file.

Step 3: Preparing QCX and USBasp device

Connect your USBasp programmer device to the pins accordingly as shown in the picture below.

Step 4: Flashing the new Firmware

• Connect USBasp programmer to computer USB port.
• In Windows File Manager go to the folder of avrdude file run upgrade.bat file.
• It will start flashing the controller. Wait until the firmware uploading is complete. It should take around 20-30 seconds.WHen finish OCX will reboot and you will see following screen with new firmware number.

Alternatively right click on right pane and select “Open in Terminal” and copy/paste following command and press enter.

.\avrdude -c usbasp -p ATmega328p -e -v -v -U flash:w:"T1.09a.hex":i
