OpenBeken 4-Relay Board: How to Script Break-Before-Make Logic With Delay?

New to OpenBeken

Just flashed 1.18.155 onto a BK7231N Cb3S chip. All good

Chip controls 4 buttons and 4 relays.

Was hoping I could create a template or script or rule to ensure "break before make" logic on the relays

Is this possible?, if so, kindly help an old man
AI: Could you please describe how your relays are wired and what they are controlling? For example, are they switching mains power, and do any of the relays need to be interlocked so they’re never on at the same time?
4 buttons control 4 relays individually
AI: Can you share a bit more about the exact “break before make” behavior you want—like, which relays should never be on together, and do you need a specific delay between turning one off and the next one on?
Example: Push button 1 = relay 1 on. Push button 3 = relay 1 off - short delay - relay 3 on. etc etc.

Hmm, you can either do it manually in OBK script or Berry (we have Berry-enabled build), or maybe you could try the PinMutex driver which I made recently for one of our users?

@spleefer90 is PinMutex still working good for you?

>>21636597 Hi and thank you for answering
I am completely new to scripting in OpenBeken, but I am trying my best, but it seems my firmware is very limited in scripting functionality. I tried with various commands in my autoexec.bat:
setChannel
backlog
led_enableAll
gpio
delay
But the commands are not recognized at all. Tried the AI approach with ChatGPT, but no luck either.
Do I need to enable a driver, or do I have some sort of minimal firmware? I am running on the latest 1.18.155
