Read pin logic level both from M3 and C28 in a Concerto device

Hello!

I have a Concerto device.

Can I read pin logic level both from M3 and C28 units in a Concerto device ???

For example the F28M35H52C1 device in the package HTQFP has the PC4_GPIO68 at pin 37,

with C28 I can read pin logic level using register "GpioG1DataRegs.GPCDAT.bit.GPIO68",

wjth M3 I can read pin logic level using API "GPIOPinRead(GPIO_PORTC_BASE,GPIO_PIN_4)".

But can I read both from M3 and C28 ?

How can I configure "GPIOPinConfigureCoreSelect(GPIO_PORTC_BASE,GPIO_PIN_4, - core M3 o core C28 - ?)"

Thankyou in advice ...

Hi,

Do you mean reading a pin simultaneously for both M3 and C28 configuration?

Yes,

reading simultaneously for M3 and C28 processors.

I have do some tests but, if I don't mistake, probably this can not be done.

I take "blinky sample dual" in the controlsuite and I modify M3 code in order to set LED_1_PIN in accord to logic level of LED_0_PIN (controlled by C28) but I can't read.

I there a way ?
