Error when using with WT32-ETH01 Board

[rybitski]

When compiling on the WT32-ETH01 (ESP32 based board with wired ethernet) The board spits out an error in the serial monitor on boot E (9) gpio: gpio_set_level(226): GPIO output gpio_num error

Every pin is configurable

Please try example

https://github.com/igorantolic/ai-esp32-rotary-encoder/blob/master/examples/Esp32RotaryEncoderBasics/Esp32RotaryEncoderBasics.ino

And adjust the values for pins depending on microcontroller (in case of ESP32 after the #else part

#if defined(ESP8266) #define ROTARY_ENCODER_A_PIN D6 #define ROTARY_ENCODER_B_PIN D5 #define ROTARY_ENCODER_BUTTON_PIN D7 #else #define ROTARY_ENCODER_A_PIN 32 #define ROTARY_ENCODER_B_PIN 21 #define ROTARY_ENCODER_BUTTON_PIN 25 #endif #define ROTARY_ENCODER_VCC_PIN -1

Certainly, changing the pins is how I was able to make this function for the WT32-ETH01. I've loaded the "Esp32RotaryEncoderBasics" example. Below are the pin assignments I've chosen.

#define ROTARY_ENCODER_A_PIN D6
#define ROTARY_ENCODER_B_PIN D5
#define ROTARY_ENCODER_BUTTON_PIN D7
#else
#define ROTARY_ENCODER_A_PIN 39
#define ROTARY_ENCODER_B_PIN 36
#define ROTARY_ENCODER_BUTTON_PIN 15
#endif
#define ROTARY_ENCODER_VCC_PIN -1 /* 27 put -1 of Rotary encoder Vcc is connected directly to 3,3V; else you can use declared output pin for powering rotary encoder */

Regardless of what I change these values to I still get the error. To be clear- the code complies, but when the ESP32 reboots in spits out the error on the serial monitor. Somewhere in the library (or included) there is a reference to a pin that is not listed here. For reference here is some info on the dev board I'm experiencing the issue with: link

and you verified documentation? https://www.esp32.com/viewtopic.php?t=33952 or youtube Spiess Andreas pins I don't use for ESP32

[rybitski]

I've used this board in multiple projects up to this point. I can't say for certain that the documentation is 100% correct. I can say that if I connect switches to pins 36, 39, and 15 that I can use those as inputs without issue. The problem only arises when compiling and running this library. (which is quite nice- hence why I'm reporting an issue to try and contribute) I know it is tempting the think commenters are overlooking simple things, but this appears to be a legitimate issue. I've tried the following assignments with the same results.

#define ROTARY_ENCODER_A_PIN 14
#define ROTARY_ENCODER_B_PIN 12
#define ROTARY_ENCODER_BUTTON_PIN 15 

AND

#define ROTARY_ENCODER_A_PIN 2
#define ROTARY_ENCODER_B_PIN 4
#define ROTARY_ENCODER_BUTTON_PIN 12 

Thanks for your responses. It can be hard to support ALL ESP32 hardware especially if you don't own it. I'm happy to look into sending you a dev board if you are interested in trying to reproduce.

UPDATE- If I assign a pin to VCC PIN instead of -1 the issue goes away.

#define ROTARY_ENCODER_VCC_PIN 4

Looks like there is an issue with passing -1 as a pin.

[rybitski]

AiEsp32RotaryEncoder.cpp line 135 AiEsp32RotaryEncoder::AiEsp32RotaryEncoder(uint8_t encoder_APin, uint8_t encoder_BPin, uint8_t encoder_ButtonPin, uint8_t encoder_VccPin, uint8_t encoderSteps)

-1 does not fit in uint8_t

[rybitski]

There are a few fixes- change the library so that if the VCC pin is set to a unsigned int that is not likely ever going to be a pin that is used (ex: 999)

if (this->encoderVccPin /= 999)
	{
		pinMode(this->encoderVccPin, OUTPUT);
		digitalWrite(this->encoderVccPin, 1); //Vcc for encoder
	}

Change the uint8_t data type to an int to allow it to hold -1.

Are there other options that I'm missing?

[igorantolic]

use the last version. It is int not unit anymore

see

https://github.com/igorantolic/ai-esp32-rotary-encoder/issues/63

and https://github.com/igorantolic/ai-esp32-rotary-encoder/blob/master/src/AiEsp32RotaryEncoder.cpp#L193

AiEsp32RotaryEncoder::AiEsp32RotaryEncoder(uint8_t encoder_APin, uint8_t encoder_BPin, int encoder_ButtonPin, int encoder_VccPin, uint8_t encoderSteps, bool areEncoderPinsPulldown_forEsp32)

I will install the library manually- it looks like my Arduino 2.3.2 IDE thinks 1.4 is the latest. Sorry to open up an old issue.

[igorantolic]

for me Arduino 2.3.2 IDE says 1.6 Ininstall and then verify if there is a newer version on dropdown left of the install button Update seems to be moved (hidden) on Arduino 2.3.2 IDE - 3 dots menu on the right / Other versions

Please verify that
