Arduino Nano with SoftwareSerial and interrupts

Projects Networking, Protocols, and Devices

I am using Hardware UART, SoftwareSerial in my project and now I wat to add interrupt handler to one pin. Will this work ? I read somewhere that SoftwareSerial and interrupts don't work together.

An external interrupt pin? Or a pin change interrupt?

Get a Mega, and quit worrying.

I'm talking about hardware interrupt, which occur in response to an external event, such as an input pin going high or low. Which one ? I don't know .. does it matter ?

Mega is not an option at the moment :slight_smile:

OK. So, you don't need to use pin change interrupts, so there will be no conflict with SoftwareSerial.

Of course it does.
