I have a problem with Arduino Atmega Nano with Atmel MEGA 328 after using Teensyduino 3.0.
The code doesn't want to upload. LEDs do stop blinking for a moment on the Arduino Nano, but than I get a message: avrdude: stk500_getsync(): not in sync: resp=0x00
What do I set in "Tools" menu to make it work?
Comport 3 or Comport 9?
What do I choose in "Programmer" menu?
USB menu grayed out ... When I tried to download new copy of Arduino software and run that, there was no USB menu. Is there any way I can make sure that Arduino compiler software doesn't access any folders that have old Teensy settings in them? Where do I find those files that tell new Arduino compiler installation what old settings were?
I installed FTDI drivers. How do I know where and why the USB is not working? This issue has nothing to do with the code I am writing to the Arduino Nano.
Teensy worked like a charm but there are some modifications that had to be done to Adruino software to make Teensy work. What do I do now? Try it on a different computer? :grin:
