Instant Interrupts - Revisited

[Ioannis]

Darrel has changed the way DT-INTs work now.

It may surprise but is far better now.

Happy burning

Just so I don't miss anything, can you direct me to more information on how they have changed? Is that on line?

For the practical side, users just get a descriptive message as of what to do in the main program. This errors,that are instructions really, may scare a little. But they just tell you what to do.

Regarding the setup there is no change for the users.

Thanks for taking the time to point this out for me.

Like many things, it seems obvious now that you say it, and I get to slap myself on the forehead again.

It's working fine.

Hi Darrel,
i found a problem which is not clear to me:
I hava a 18(L)F25K22 and want to use SSP1_INT for my I2C handler, but after compiling the source, i get this error:

....test.asm 1052 : Symbol not priveiously defined (SSP1IF)

When defining SSP2_INT there is no error.

Regards,
Ralf

Ralf,

What version of MPLAB are you using?
I don't get the error when compiling for SSP1_INT here.

When dealing with new chips like the 25K22, you should always keep up to date.
Current MPLAB version is 8.66.

Hi Darrel,
yes you are right, i had 8.56, now 8.66 and it works.

BTW: For all I2C Slave progger:
To get the I2C Slave running on a 25K22, use SSP1_INT or SSP2_Int, and, very important, you must set ANSC4 & ANSC3 = 0 for SSP1 and ANSB1 & ANSB0 = 0.

Ralf
