FreqMeasure with 1284P

[bvernham]

I would like to use the FreqMeasure library with the 1284P but the library has not defined that microcontroller.

Can someone help me modify so I can use that library with the 1284P?

The ATMEGA1284P is mounted on the Bobuino board.

Thanks

Edit util/FreqMeasureCapture.h. Maybe copy one of the other board defs as a starting point?

If you actually get it working, maybe share the solution here, or send a pull request on github.

Which input capture is used?:
#define CAPTURE_USE_TIMER1
#define CAPTURE_USE_TIMER2
#define CAPTURE_USE_TIMER3

1284P has 3 timers.

Thank

You're going to have to research the timers, perhaps comparing to the ones on the supported boards, and figure out which pin. You have to do that part....

Can I get a hint?

I see ICP1 and ICP3 but ICP3 is also shared with the SPI buss so I want to specify the library to use ICP1.

Is this possible?

Thanks
