B4R Question attachInterrupt ?

[Jaames]

Hi, is this function implemented in B4R already or will it be ?

Interrupts are very important functionality
of microcontrollers , and arduino IDE have it's own implementation :

Running code from interrupts is very problematic. You can use interrupts in B4R from a library however the B4R code will run outside of the interrupt. You can see an example in the rWire library source code.

You can add listeners to pins with Pin.AddListener. This listener is not based on interrupts. The latency on Arduino Uno should be around 50 microseconds (0.05 milliseconds).

I was "afraid" of similar answer , but hey, which other IDE have events attached so simple to the pin?
AFAIK there is none. With latency that small, it can replace physical interrupts on any pin .
I'm satisfied with ability to attach events to the pins . Thanks for another great product.

Hi Erel,
This will mean employ a pin just for hardware interrupt and can not use it for any other purpose. correct me if I am wrong.
will need 2 pins for maskable and non-maskable interrupts.

Currently you cannot use hardware interrupts with pins at all.

All pins allow you to add a listener with the AddListener method.

There are many types of interrupts, but the way B4R works, hardware interrupts are almost replaceable with pin.AddListener (I se it as event in other B4X products)
