GPIO memory mapping on OSK5912

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...

Using C5510 HPI as GPIO

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...

Re: GPIO in C6713

Hello. Problem is now solved. It was that the HPI is multiplexed with the GPIO and at reset one specific pin (H14) must be pulled down via an external resistor. Thanks for you answers. ...

Re: UART on EMIF ? (C6000)

There's an app note on connecting a UART to McBSP. I don't remember there being one about connecting to EMIF though. Only 2 of the clock pins on the EMIF can be configured as GPIO. If your're not using the HPI then you can use the GPIO module of the 6713. The pins are muxed though so you can ...
