Photon USART Interrupt

Hi, I’d like to generate usart interrupts, however I think that all of their “handler” functions are defined in “usart_hal.c”, so I am not gonna be able to define them again in the user code, right?
If this is the case how can I generate an usart interrupt?

how can I generate an usart interrupt?

Any response to this question?

Can you clarify a bit more what you’re after?

And I already had proposed something like this but it was “dismissed” as no call for it

This way you’d not exactly have an ISR but a callback triggered from an ISR which might suffice for most needs IMHO.
