all in one pcb use H11L1 optocoupler IC can use 6n138 its same
- Visual Inspection & Plug Socket orientation check
- Your All-in-One board stops a working machine?
- Does you pi die (no leds) when you connect All-In-One board?
If so you have a Power Supply short on All-in-One.
- Can you measure voltages? Check (using schematic …) Check PSU pins on All-In_One board.
Continuing the discussion from Encoders on MCP23017:
THIS ENCODER WIRING TO ALL IN ONE MODULE COMPATIBLE
What is exactly your layout configuration? If you disconnect the All-In-One circuit and configure “Dummy” wiring layout … does it work OK?
Have you tried to test your encoders from the command line?
You also can check if the MCP23017 is “on-line” for the RBPi. Just run this command:
The default address of the MCP23017 GPIO expander is 0x20
1.How do I connect wiring a rotary encoder to switch intelligently all in one module pcb
2.whether to add a capacitor on the back of this such as the pcb looks in this picture?
this standard all in one module from gifthub zynthian hw
Take a look to this post
If you can make these encoders work on zynthian, please give me the recipe hahaha! I have not been able to make them work. I’m using the same model on the official all-in-one board.
do any of the encoders produce a response?
