Errors uploading with multiple inputs and logarithm/linear adjustments and the main-branch library #46

Closed rabbiccu closed 6 years ago

rabbiccu commented 6 years ago

I was having strange crosstalk and sporadic functionality on A0-A4 so I decided to load the new library from the main branch. I also noticed the pots were functioning logarithmic, so I found your calibration example and implemented that into my sketch. I am using:

MIDI CONTOLLER: main branch Arduino IDE 1.8.5 Arduino Leonardo

CODE

This is an example of the "Analog" class of the MIDI_controller library.
Connect a potentiometer to analog pin A0. This will be the MIDI channel volume of channel 1.
Map it in your DAW or DJ software.
Set 'minimumValue' to the analog value read when the potentiometer is in the minimum position.
Set 'maximumValue' to the analog value read when the potentiometer is in the maximum position.

#include <MIDI_Controller.h> // Include the library

// Create a new instance of the class 'Analog', called 'potentiometer', on pin A0,

Analog potentiometer_B(A1, MIDI_CC::Sound_Controller_2, 1);

const int minimumValue = 3;    // the analog value read when the potentiometer is in the minimum position.
const int maximumValue = 1020; // the analog value read when the potentiometer is in the maximum position.

int mapCalibrated(int value) {
  value = constrain(value, minimumValue, maximumValue); // make sure that the analog value is between the minimum and maximum value
  return map(value, minimumValue, maximumValue, 0, 1023); // map the value from [minimumValue, maximumValue] to [0, 1023]

I am enjoying this, again thanks for input.

tttapa commented 6 years ago

That's an error during upload, not a compilation error. The code is fine. Try resetting the board during upload, and make sure you select the correct serial port.

rabbiccu commented 6 years ago

Done, again it was an issue with my uploading and the reset button needs to be mashed in just the right way.
