Encoder not working properly on pins 19 and 18 Teensy LC

[SwooshMihu]

I have a little problem with the implementation of 1 encoder. The encoder connected to pins 19 and 18 gives the same signal when rotated either way. This is the code i am using:

include // Include the Encoder library.

// This must be done before the Control Surface library.

include // Include the Control Surface library

USBMIDI_Interface midi;

///////////////////Defining Bank/////////////////////// Bank<4> bank1(2); IncrementDecrementSelector<4> selector = { bank1, // Bank to manage {8, 13}, // push button pins (increment, decrement) Wrap::Wrap, // Wrap around };

/////////////////////////////////////Banking encoders////////////////////// Bankable::CCRotaryEncoder enc1 = { {bank1, BankType::CHANGE_CHANNEL}, {21, 20}, // pins //{MIDI_CC::Channel_Volume, CHANNEL_1}, {MCU::V_POT_1, CHANNEL_1}, //MCU::V_POT_1, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough }; Bankable::CCRotaryEncoder enc2 = { {bank1, BankType::CHANGE_CHANNEL}, {19, 18}, // pins //{MIDI_CC::Channel_Volume, CHANNEL_1}, {MCU::V_POT_2, CHANNEL_1}, //MCU::V_POT_1, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough }; Bankable::CCRotaryEncoder enc3 = { {bank1, BankType::CHANGE_CHANNEL}, {17, 16}, // pins //{MIDI_CC::Channel_Volume, CHANNEL_1}, {MCU::V_POT_3, CHANNEL_1}, //MCU::V_POT_1, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough }; Bankable::CCRotaryEncoder enc4 = { {bank1, BankType::CHANGE_CHANNEL}, {15, 14}, // pins //{MIDI_CC::Channel_Volume, CHANNEL_1}, {MCU::V_POT_4, CHANNEL_1}, //MCU::V_POT_1, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough }; Bankable::CCRotaryEncoder enc5 = { {bank1, BankType::CHANGE_CHANNEL}, {12, 11}, // pins //{MIDI_CC::Channel_Volume, CHANNEL_1}, {MCU::V_POT_5, CHANNEL_1}, //MCU::V_POT_1, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough }; Bankable::CCRotaryEncoder enc6 = { {bank1, BankType::CHANGE_CHANNEL}, {10, 9}, // pins //{MIDI_CC::Channel_Volume, CHANNEL_1}, {MCU::V_POT_6, CHANNEL_1}, //MCU::V_POT_1, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough }; //////////////////////////

void setup() { RelativeCCSender::setMode(relativeCCmode::TWOS_COMPLEMENT); Control_Surface.begin(); }

void loop() { Control_Surface.loop(); // Update the Control Surface }

Check out the output on MIDI-ox, while testing the encoders you can clearly see this one is problematic:

As far as the wiring goes, all encoders are wired properly and i have also tried using an already tested encoder on those two pins with the same result.

Even when using the following code, you can notice that it increments in the same direction, no matter in which way i twist the encoder.

include // Include the Encoder library.

include // Include the Control Surface library

// Instantiate a MIDI over USB interface. USBMIDI_Interface midi; // Instantiate a CCAbsoluteEncoder object CCAbsoluteEncoder enc = { {19, 18}, // pins MIDI_CC::Pan, // MIDI address (CC number + optional channel) 1, // optional multiplier if the control isn't fast enough };

void setup() { Control_Surface.begin(); // Initialize Control Surface }

void loop() { Control_Surface.loop(); // Update the Control Surface }

Pins 18 and 19 are not interrupt pins. Please see the link I posted in your previous issue.

Control Surface uses the PJRC Encoder library to read the encoders, so I'd recommend trying the Encoder library examples first to debug this.

[SwooshMihu]

Thing is, i have an encoder connected to pins 16 and 17 which according to this schematic do not have the intrrerupt functionality and it works fine

[tttapa]

Do the Encoder library examples work?

[SwooshMihu]

it does work on 16 and 17, does not work on 18 and 19

[tttapa]

Then this is a problem with the Encoder library, not Control Surface. If this is a known issue, you can probably find it on the PJRC forums.

i shall check it out, meanwhile the fix i found was connecting the encoders to 16-18 and 17-19 respectively and it fixed the problem.
