[SOLVED] Serial communication doesn't work – Focus plugin

question

#1

Solved: I had to send the command with an option (in Arduino’s Serial Monitor) newline.

Hi,

I’m kinda lost. I’m trying to experiment with Focus plugin but I can’t get Serial work. See the example attached below. Once I compile that firmware I open Arduino’s Serial Monitor (on 9600 baud) but the only thing I get is .. I’ve tried help, version, example command but I get nothing than . :frowning_face: :

  return true;
}

KALEIDOSCOPE_INIT_PLUGINS(Focus);

void setup() {
  Serial.begin(9600);
  Serial.println("Hello Computer");

  Kaleidoscope.setup();

  Focus.addHook(FOCUS_HOOK(exampleFocusHook, "example"));
  Focus.addHook(FOCUS_HOOK_HELP);
  Focus.addHook(FOCUS_HOOK_VERSION);
}

void loop() {
  Kaleidoscope.loop();
}

Does anyone have a clue what’s going on?

Thanks in advance, I hope we can solve it somehow.

Best,

Jakub

EDIT:

This is the screen from IDE, so I guess I have all the drivers. Using macOS 10.13.6.

EDIT 2:

I’ve tried my SUPER CUSTOM FIRMWARE (my Arduino UNO was actually able to run/display this correctly)

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
  Serial.println("hello");
}

// the loop routine runs over and over again forever:
void loop() {
}

nothing. So I guess… something is wrong, right? :sob:

EDIT 3:

Not everything is lost! I’ve tried to add Serial.println("Hello") into loop function and I can get the message! So I don’t know, is something wrong with Focus plugin?

Glad you got it sorted out!

Focus is a mostly line-oriented protocol, so commands need to end with a newline (ideally \r\n, but \n works too).
