RC-Thoughts Firmware Uploader Updated – Need testers!

I would be happy if people would test RC-Thoughts Firmware Uploader in various computers. Application is updated with correct dll-files and is now tested by me in Windows 10 64-bit and Windows 7 32-bit. (I don’t have others to test with myself) Not compatible with Windows XP.


  • 32-bit software, dll’s included
  • Uses avrdude for the actual upload
  • Minimal hazzle with settings
  • Indicates successful or failed upload


These operating systems have been verified to work at least on one user – Please report here what windows you are on and if it worked or not. I’ll update this as report’s starts to drop in.

  • Windows 10 64-bit
  • Windows 7 64-bit
  • Windows 7 32-bit

Comparison to XLoader

  • More reliable status of upload-process
  • Always shows correctly successful / failed upload
  • Faster timeout in case of failed upload
  • Works with 3.3V 8Mhz and 5V 16Mhz Arduino Pro Mini’s without settings-changes

Main difference to XLoader is that often XLoader does not update the status-strip. Also XLoader does not monitor the avrdude-process so user needs to open taskmanager and kill it.

RC-Thoughts Firmware Uploader tries to make sure avrdude-process is not left to hang. Also there is no need to close/reload the app in case of missed upload.

Timing of pressing “Upload” and pressing Arduino’s reset-button is as critical as before, this has to do with avrdude. You’ll get really consistent result if you first press the upload-button and then quickly with same hand press the reset-button on the Arduino. As with any other avrdude-uploader, you’ll just have to learn it.


For 32/64-bit Windows 7/10 zip-package HERE. (v.1.0.3)

Extract zip-package and run RCT-FW_Uploader.exe. The folder “Extras” has two Arduino Blink-files to test with. If you do not see correct serial-port you can re-scan port’s with the “Scan”-button.
