Port Expander library , Single bit reading

#1 Post by kentar » 04 Nov 2021 16:17

In Port_expander library I can read PortA and (or) PortB as byte

function Expander_Read_Byte(ModuleAddress, RegAddress : byte) : byte;

How can I read an individual pin , for example PortA.7 ?

Hi,

You can only do a full byte read and then extract the necessary bit.

Regards,
Filip.
