GPIO memory mapping on OSK5912

sleve_ex - 2007-01-17 07:28:00
I'm currently working on driver design in Windows CE using OSK5912 development board together with Mistral QVGA LCD module. The driver will map and control the input and output of the GPIO pins. The problem is that I have difficulty in mapping the GPIO registers to the OS. When I tried to map it...GPIO memory mapping on OSK5912

Using C5510 HPI as GPIO

rickman - 2006-03-24 18:49:00
It has been awhile since I have used the C55 family and I can't remember if they support using the HPI as GPIO if you are not using the HPI. I seem to recall that some of the TI DSPs can do that, but I don't see anything in the docs that says the C5510 is capable of it. Anyone know for sure i...Using C5510 HPI as GPIO
