Hi,

I am finding the documentation for GPIO numbers a bit confusing.

Am I correct :

   

HT1 = GPIO1
HT2 = GPIO2
HT3 = GPIO3

Am I correct :

   

P39 = GPIO39
P40 = GPIO40
P41 = GPIO41

Finally, Can any of these pins be assigned for TX/RX for D0/D1 with Weigand Protocol?

Hopefully, this will allow me to configure my entry alarm system.

Many thanks in advance.

Paul
