Due some problems with programming a nano with Atmel studio, i changed the fuses with what i tought to had to be the correct fuses from the arduino ide. However now there cannot be any communication with te nano. I tried USB(arduino ide) and a avrsipmkII programmer in Atmelstudio.
The fuses in Atmel studio where : Low:0xFD , High:0xDA , Extend:0xFD The fuses in Arduino IDE where : Low:0xFF , High:0XDA , Extend:0x05
For what ik could find (using www.engbedded.com/fusecalc )is the only change in the Lowerfuse byte van importance right ? This a change from:
Ext.Crystal Osc: Frequency 3.0-8.0-MHz; Start-up tim PWRDWN/RESET: 16K CK/14 CK + 65ms;[CKSEL = 1101 SUT=11]
Ext.Crystal Osc: Frequency 8.0-MHz; Start-up tim PWRDWN/RESET: 16K CK/14 CK + 65ms;[CKSEL = 1111 SUT=11]
For the Extendedfuse byte are only the first 3 bits used which were not changed. Although i changed the last 5 to a "0" in stead of a"1" (default).
Can this be the problem to communicate with the nano ? Can ik solve this or is the nano (can i really use FUBAR in this case :D) ?
