- Fri Mar 17, 2017 3:55 pm #63860 Hello,
I have an ESP-07 modules, however, the Interupt does not work on the GPIO16 and GPIO12, i use 10K Pulldowns.

GPIO14 - Works
EDIT: i use ESP Basic 3.0.Alpha 66

Code: Select all[isr]
interrupt GPIO16, [switch1]
wait

[switch1]
if io(laststat,GPIO16) = 1 then print "Hello"
goto [isr]

- Sat Mar 18, 2017 4:34 am #63881 I RTFM and ESPBASIC use Prolling for Interups

"Will execute a specific branch when a pins status changes. The interrupt polling only occurs when the esp is waiting and useful for things like push buttons trigger events. The branch must end with the wait command."

"You can have interupts on any of the i/o pins and there is no limit to how many you can have except the number of pins available."

But why does GPIO12 not work?

- Sat Mar 18, 2017 6:00 am #63885 Ok, then it's probably a bug in ESP8266Basic.ino in RunBasicTillWait() in for (int pinn = 0; pinn <= 15 - probably there should be 16. For GPIO12 check PinListOfStatus[12] value...
