The line must be requested from the chip to access the value. Once requested, the line info can also be read from the line: inf, _ := l.Info() infs, _ := ll.Info() Info Watches Changes to the line info can be monitored by adding an info watch for the line: func infoChange...
Each interrupt line is asserted for one clk_i if an interrupt occurs on the respective pin or asserted and held on an unamsked interrupt until the respective interrupt has been cleared depending on the pin_lvl_intrpt_mode setting in the CFG register. reg_req_i input Control interface request...

A watch can be removed by closing the line: Also see thewatcherexample. Find Lines can be found by the GPIO label name as returned in line info and set by device-tree using theFindLinefunction: chipname,offset,_:=gpiod.FindLine("LED A")c,_:=gpiod.NewChip(chipname,gpiod.WithConsumer...
