I did it really fast... like 50 times. I even tried in russsian, always the same result. Tried on w10, w7,forcing drivers, diferents pcs, no antivirus, trial mode, you name it...
Eventually fond THIS https://sourceforge.net/projects/arduinodev/files/ArduinoBuilder/FreematicsArduinoBuilder-1.0.13-win32.exe/download
With it I was able to upload the hex file. I´ve tried X-loader first and it wouldnt work either. I think im having some funny interaction or something, it can be that I wasn´t able to google someone with some similar problem.
Thanks for the response! Im gonna go now to have some new problems configuring those allegro sensors! :megalol:
