💅 NAME 💅

PPoll — parallel poll devices, bestie. yes it's literally that.

✨ SYNOPSIS ✨

okay so first you gotta pull in the header, no cap:

#include <gpib/ib.h>

and then the function itself is giving:

void PPoll(int board_desc, short *result);

🦋 DESCRIPTION 🦋

ngl PPoll() is basically the twin sister of ibrpp(), the 'traditional' API function — same energy, different era. 🫶

what it does is tell the interface board to go do a parallel poll, and then it drops the parallel poll byte right into the place you pointed at with result. iconic behavior honestly.

now the byte itself?? bits 0 to 7 correspond to the dio lines 1 to 8, and a 1 means that matching dio line is asserted. so like, a little 8-bit vibe check on your whole bus. 🔥

⚠️ important one, bestie: the devices on the bus you wanna poll have to be configured beforehand using PPollConfig(). no setting up mid-poll, that's not the move.

and the board must be controller-in-charge to perform a parallel poll. periodt. 👑
