Hi. I'm trying to use the Adafruit_BBIO.Encoder library on kernel 4.4.87, but cannot seem to get it working. I think everything initializes ok, but my readings are just continuous '0'. I think the issue might be that I can't configure the pins: ``` root@bela:~/Robut# config-pin P8.33 qep P8_33 pinmux file not found! bash: /sys/devices/platform/ocp/ocp*P8_33_pinmux/state: No such file or directory Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P8_33_pinmux/state ``` I have the universal cape loaded: ```root@bela:~/Robut# cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,BB-PWM1 5: P-O-L- 1 Override Board Name,00A0,Override Manuf,cape-universaln 6: P-O-L- 2 Override Board Name,00A0,Override Manuf,BB-ADC ``` I get that for all the pins I try to configure. I went through the HDMI disable in /mnt/boot/uEnv.txt: ``` disable_uboot_overlay_audio=1 disable_uboot_overlay_video=1 ```
My code is : ``` from Adafruit_BBIO.Encoder import RotaryEncoder, eQEP2, eQEP1 Enc1 = RotaryEncoder(eQEP1) Enc1.enable() Enc1.setAbsolute() Enc2 = RotaryEncoder(eQEP2) Enc2.enable() Enc2.setAbsolute() print (Enc1.position) print (Enc2.position) ``` Is there anything I'm doing wrong or not doing?
