Hardware serial problem

[marco12345]

Hi, I want use HW serial to have a bidirectional comunication with a VMUSIC module, the RX is OK, but I can't send commands. I have verified the TX with a logic analizer and I have found that Arduino send a byte(1 or 3) a CR,LF and then the char in serial.print().

It is possible TX only what is in serial.print()??

Thanks!

Are you sure you're not using "Serial.println()" instead of Serial.print() ?

Hi,
sure, I have try also serial.write() but is the same thing!

So, now you need to post your code. It is unlikely to be a hardware problem.

Thanks to all!

It was a SW problem! I was using the analog button library that have an hidden serial.println() in it to trasmit the number of button pressed.I have modified the AnalogButtons.cpp file and now it's working well!
