$if _type command

[SCV]

Hi,

Looking to search for instances where the device is a dsPIC33CK***. To save me listing every _DEVICE I though I could use _TYPE but manual (p448) doesn't list CK devices.

Code Select Expand

$if _type = DSPIC33CK doesn't work.
What is the correct syntax here?

Thanks,
Tim.

I am doing this way.

Code Select Expand

$if _device = _18F87K90
    ....
$elseif _device = _18f8722
    ....
$endif

So it should have "_" at the beginning.

Thanks Yasin, I had put the underscore in my programme but not typed it correctly here.

To be clear...

$if _device = _33CK64MP205   works ok
$if _usart = 3               doesn't work
$if _type = _DSPIC33E        works ok
$if _type = _DSPIC33C        doesn't work
$if _type = _DSPIC33CK       doesn't work

$if _usart = 3              doesn't work
The correct define for the 16-bit parts is '_uart' (no usarts in these parts)

$if _type = _DSPIC33C        doesn't work
There is no 'C' type defined... currently just 'CK'

$if _type = _DSPIC33CK      doesn't work
Works ok here

The device information for the preprocessor is held in each device's ".def" file. For example, the DSPIC33CK64MP506 has the $defines:

All working now, thanks everyone.

I was wrong to say it's not working, it's just the _DSPIC33CK wasn't highlighting as _DSPIC33E does. I remember now Les mentioning something about this before...
For the USART / UART it's a typo in the Proton 24 manual!

Cheers
