I have just built my second Shruthi control board and observe some strange behavior with the encoder:
it always moves forward (increasing patch number or cycling right), even if I turn it to the left.
Otherwise everything seems to work fine: display and sound behave like they should and I can change presets in both directions via MIDI. The push behavior of the encoder does also work.
I looked through the forum for similar discussions and found some places were encoders behave strangely. But I could not identify what could be the reason in my case. So that’s why I am asking here for advice.
Some more specific information:
I have ordered the board and the programmed chips from here, and the parts by Mouser. The encoder has the ID 652-PEC12R-4225F-S24 (Bourns Encoders), just as recommended in the BOM. Firmware is 1.02 and I also checked that it is not in XT mode. All other switches and nobs seem to perform well.
Does anyone have a hint what could be the reason? Or suggestions how I could test malfunction of the encoder?
Previous builds: one controller board and three filter boards (SMR4 mkII, ladder and Steiner Parker)
