Question about an old thread - Open ChargerPort

This site may earn commission on affiliate links.
I'm trying to replicate this post --- Open ChargePort
Mainly looking at Si4010 version in that post.
Below is my schematic:
1695218431547.png


Only difference between original design and this is the IC variant. Mine is 10 Pin original is 14 Pin.
I have downloaded the code to the IC provided at (Open-Chargeport/Si4010/source at master · mstegen/Open-Chargeport)
I couldn't see any signal on TXP TXM pins (on oscilloscope) after pushing button SW1.
Do I need to change pins in code? I looked at the code but couldn't find the location where I can change pin. I could see line 171 related to GPIO. No idea what to change there!
@fuzzylogic.1161 is the original author I couldn't tag user id for better visibility.

Any ideas are highly appreciated.
