Meaning of "IN5"?

Vincenzo1309

Dear all,

I am now working on a project using the Bluetooth embedded transceiver. I am connecting my computer using a Bluetooth dongle to the transceiver.

I keyed in the following command in my program to check if there is any Bluetooth connection between the dongle and the transceiver

Do until IN5 = 1 : Loop

So if there is a connection, the program will proceed to the next command, else it will always be in a loop.

I know the meaning of the number 5, since pin 5 is the status pin of the Bluetooth transceiver.
But what is IN??

Kindly advise...

Thanks and Regards,

In = INPUT. The pins can act as inputs or outputs. To control something (an output), HIGH/LOW pin is normally used, but also
DIR3 = 1
OUT3 = 1
Could also be used - DIR, make an output
OUT3, set output 3 to high

IN5 simply returns the state when it is an input, if input is high or low.
