Weird serial monitor data #13

Open ittnerm opened 10 years ago

ittnerm commented 10 years ago

Dear all,

I bought several days ago the 9DOF module and setup the hardware as mentioned in your tutorial, uploaded the software code of your tutorial and I set all the parameters correctly (e.b. Baud Rate 57600). However, there seems to be an error somewhere, because the serial monitor shows only weird data readings (see attached screenshot / picture).

I googled a lot to solve the problem by myself, but I haven't been able to solve it - thus, I would appreciate your help to solve this issue :) Thank you in advance for your answer!!!

Okay, might have found the solution, @ittnerm. If you upload the sketch with the Arduino IDE having selected the wrong microcontroller (e.g. ATMega 328 16MHz instead of ATMega 328 8MHz) it will give you the strange serial output. Selecting the right chip fixed the issue for me.
