[BUG] (Rotary encoders error on ENDER 3 V2 and BTT E3 RRF) #22639

Closed krubbitt closed 3 years ago

krubbitt commented 3 years ago

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

So i just bought a BTT E3 RRF board and i´m trying to make it work on my ender 3 v2 printer but seems like the software its not correctly made for the DWIN screen that it has. Looks like the option is there but is not working at compiling.

I made a lot of compiles each time i made a change and the change that gives me the error is when i place the #define DWIN_CREALITY_LCD Even in a new and unmodified Marlin code only changing the screen.

Bug Timeline

No response

Expected behavior

Compile without errors

Actual behavior

'ENCODER_PHASE_0' was not declared in this scope 'ENCODER_PHASE_3' was not declared in this scope 'ENCODER_PHASE_1' was not declared in this scope 'ENCODER_PHASE_1' was not declared in this scope 'ENCODER_PHASE_2' was not declared in this scope

Steps to Reproduce

use #define DWIN_CREALITY_LCD

This is not a bug, your trying to add a E3V2 lcd to a non supported controller. At best its a feature request

You need to add BTN_EN1, BTN_EN2 and BTN_ENC pin definitions

 */

As you can see you cannot just plug this LCD into this controller, it needs a special cable to break out the RX1 and TX1 lines to a serial port. The TFT port would be the obvious choice.

Add

define BTN_ENC PB2

define BTN_EN1 PE11

define BTN_EN2 PB1

define BEEPER_PIN PE10

You also need to add #define ENCODER_5X_STEPS_PER_SEC 15 to your Configuration_adv.h above #define ENCODER_10X_STEPS_PER_SEC 30 // (steps/s) Encoder rate for 10x speed
