ENCODER_OPTIMIZE_INTERRUPTS not working for ATmega4809

[raindropmedia]

Description

ENCODER_OPTIMIZE_INTERRUPTS do not work for ATmega4809 (Nano Every)

When I use the optimized source code, I no longer get any values for .read ();

it works without "ENCODER_OPTIMIZE_INTERRUPTS".

Steps to reproduce the problem

Two 2400 step encoders on an Arduino Nano Every. Latest encoder library from Github from August 9th, 2020

board Arduino Nano Every

Arduino IDE version 1.8.10

Operating system & version Mac OS 10.14.6

Arduino Sketch

` //#define ENCODER_OPTIMIZE_INTERRUPTS

include

include

define enc1P1 2

define enc1P2 4

define enc2P1 3

define enc2P2 5

define bit4 A0

define bit3 A1

define bit2 A2

define bit1 A3

define led 6

Encoder knobRot(enc1P1, enc1P2); Encoder knobX(enc2P1, enc2P2);

typedef struct { int16_t x; int16_t rot; } B_t; B_t data;

byte datasend = 0; byte i2cAddress = 1; boolean ledState = false; byte ledblink;

void setup() { pinMode(bit1, INPUT_PULLUP); pinMode(bit2, INPUT_PULLUP); pinMode(bit3, INPUT_PULLUP); pinMode(bit4, INPUT_PULLUP); pinMode(led, OUTPUT); digitalWrite(led, HIGH); bitWrite(i2cAddress, 0, !digitalRead(bit1)); bitWrite(i2cAddress, 1, !digitalRead(bit2)); bitWrite(i2cAddress, 2, !digitalRead(bit3)); bitWrite(i2cAddress, 3, !digitalRead(bit4));

Wire.begin(i2cAddress); // join i2c bus with address #8 Wire.setClock(400000); Wire.onRequest(requestEvent); // register event data.x = 0; // assign a value to the long number data.rot = 0; // assign a value to the long number delay(1000); digitalWrite(led, LOW); }

void loop() { int32_t newX, newRot, tempRot; newRot = knobRot.read(); newX = knobX.read(); if(newRot<0){ tempRot = newRot % 2400; data.rot = 2400+tempRot; }else{ data.rot = newRot % 2400; } data.x = newX; Serial.print("absX= "); Serial.print(data.x); Serial.print(", absRot= "); Serial.print(data.rot); Serial.print(", absRot= "); Serial.println(newRot); //delay(1); }

void requestEvent() { datasend = Wire.write ((byte ) &data, sizeof data); / sends data ti Master */ //data.rot = 0; //data.x = 0; }`

I have the same issue, using 2 linear encoders.

Using "_//#define ENCODER_OPTIMIZEINTERRUPTS" works, but can sometimes miss steps in the encoder, while using "_#define ENCODER_OPTIMIZEINTERRUPTS" does not give me any step signal.

ENCODER_OPTIMIZE_INTERRUPTS is not working yet, but have a look at #66 as not every pin was using interrupts

Still running into this issue with the Nano Every. Has anyone come up with a workaround?
