False encoder events triggered

[riban-bw]

Describe the bug Each time an encoder is rotated there are events triggered for all encoders, not just the adjusted one.

To Reproduce Steps to reproduce the behavior:

1. Within mixer view, rotate SELECT encoder

Expected behaviour Select encoder action occurs.

Actual behaviour Select encoder action occurs and also each other encoder.

Setup:

• HARDWARE Raspberry Pi 3 Model B Plus Rev 1.3 Soundcard: HifiBerry DAC+ ADC PRO Display: ZynScreen 3.5 (v1) Wiring: MCP23017_ZynScreen GPIO Expander: MCP23017
• SYSTEM Raspbian GNU/Linux 10 (buster) Build Date: 2021-09-23 Memory: 58% (542M/923M) SD Card: 49% (14G/29G) Temperature: 59.1ºC
• MIDI Profile: default.sh Fine Tuning: 440 Hz Master Channel: off Single Active Channel: on ZS3 SubSnapShots: off
• SOFTWARE zyncoder: testing (1609f8d) zynthian-ui: testing (789ba16) zynthian-sys: testing (587dd76) zynthian-data: testing (076a23d) zynthian-webconf: testing (0de7a5e)

Additional context Detected during debugging. Adding breakpoints after each lib_zyncore.get_value_flag_zynpot call shows that this returns true for all encoders after any have changed state. This is a screenshot of my GPI config:

Sorry @riban-bw !!

I can't reproduce this issue. It works like a charm for me. I've a v4 over my desk. Could you send the log?

Thanks!

This is a V3. What log would you like to see. It is immediatly obvious if you run with a debugger and set breakpoints after each if lib_zyncore.get_value_flag_zynpot call within zyncoder_read function.

OK! I see. But it's only in the mixer, so it doesn't seem a problem with the zyncoder library. Let me do some research ...

Solved!
