Porting old EXT driver implementation to Chibi_19

[dflogeras]

Hi, I have an older project I think I used Chibi_16 vintage. As discussed in this posting:
viewtopic.php?t=3319

We figured out a way to use EXTI17 as a wakeup source. However, I relied on the EXT driver to set up the IRQ.

Now that PAL has replaced EXT, it seems to be only pad-centric (0->15). Is there a way in modern ChibiOS to set up EXTI17 in a generic fashion?

Hi,

There is an EXTI API under EXTIv1, it is used by PAL as an internal interface but can be used by application code, see stm32_exti.h/c.

Ahaa, and it looks as though the RTCv2 driver already uses it to set those IRQs up properly. I guess I should have read the driver code first.

Thanks as always,
