I don't think you're supposed to make copies of the serial ports. Not sure why the HardwareSerial copy constructor isn't deleted.
If you want to declare the serial ports separately, use references instead:...
You might be interested in the Control Surface library for Arduino and Teensy that I maintain. It comes with many building blocks for creating MIDI controllers and control surfaces and has support for the Mackie Control...
Changing the Interrupt Threshold Control value seems to alter the timing and might expose some data races.
Occasionally, packets seem to be dropped when sending very long SysEx messages using my driver. I added some...
You would inherit from the MIDI_Callback class and implement its onChannelMessage method. Then attach the callback to the MIDI interface using setCallbacks.
For example:
#include <Control_Surface.h>
#include...
Sure, the code for the T4.0 simply discards any incoming MIDI USB data (compiled with USB type “MIDI”, of course):
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH);
delay(100);
...
I've been working on a more efficient implementation of the USB host MIDI driver. It uses alternating transmit buffers and disables interrupts only for a minimal amount of time, which allows for high throughput. It also...
