Hi guys,
I am working on project which in its default form communicates with a PC over the serial link to transfer speed data.
I am currently trying to add a function where it can switch and instead output the data in MIDI format through a different connector depending on a button state (but still using pins 0 and 1 to save input/outputs).
In my current program I set the serial (Serial.begin (9600)) in the void setup, my question is can I later declare the serial port to work as midi (Serial.begin(31250)) or can the serial port only be initialised once at one speed?
Hey thanks for the reply, yeah I have tried it and it will compile however I don't currently have access to the midi receiving hardware so cannot tell if it is working correctly, was hoping someone may know.
I guess I will have to wait for then, thanks anyway though
Tommy, there is no problem with calling Serial.begin multiple times at multiple speeds. To test, I made a little sketch that prints data at two different speeds:
void setup()
{
Serial.begin(9600);
Serial.println("Hello at 9600");
delay(5000);
Serial.begin(115200);
Serial.println("Hello at 115200");
}
void loop(){}
When I set my serial monitor to 9600 I got reasonable text then garbage. At 115K it was the other way around.
I think your only concern is whether 31250 works as a baud rate.
