Hello all,
After some time I came back to use Arduinos. I just downloaded the las Arduino IDE today and plugged my board.
At the beginning I got in trouble connecting, but I selected the option Old Bootloader in the processor tab and its fine now.
I uploaded the blink sample and it works, but while the code says delays should be 1 second, my Arduino does 5 seconds instead.
I tried the analog read one too. I am getting nothing but ??x??x??X??x??x??X??x??x??X
Could someone help me please?
Thank you in advance.
Welcome back
Your topic title says "Micro" but "old bootloader" seems to indicate "Nano". Which one is it?
5x slower is odd, 4 or 8 would make more sense. Is your board a new board or did you use that same board in the past (years ago) without problems?
How did you upload blink? Via USB or via ICSP?
Thank you for your reply. It was a Typo, my bad. It is a Nano v3.0 this is what is says below the board.
You are right, I measured again at it is 4 seconds not 5. I uploaded the blink via USB. It is a new board.
Thank you for helping.
These are some guesses
It sounds like your board is running on the wrong frequency (4MHz vs 16MHz). One way to check is to set the baudrate in serial monitor to match a quarter of the baudrate in the sketch; so if your analogread sketch uses 9600, change the serial monitor to 2400 baud and see if you get readable text.
Where did you buy your Nano?
I just tried but I got the same ??x???x
I think that board was purchased 4 or 5 years ago from Bangood
I'm out of options. If you have another Arduino or a programmer, i would try to burn the bootloader.
Maybe somebody else has ideas.
I have more Arduino's and one programmer. I will see how that can be done. thank you for the help.
