Need help creating code for TMS320F2812

Michael Douthglass

Other Parts Discussed in Thread: SPRC097

I don't have much experience programming this MC, so I need some help. In some cases, after the main code I need to turn on (put 1 digital) an output pin of the MC, and turn it off in other points of the code. Which instructions do I have to use to turn the pin on/off?Neither I know which pin it is.

Thank you friends

Just curious .. if it is a new project and you are new to this family of devices why 2812? please consider later devices for more flexibility. Good luck.

Where can i see information about the gpio registers? Is there any document about that?

All documentation for the F2812 is here

But I agree it's not clear where the GPIO section would be....

Refer to the System Control and Interrupts Reference Guide for your device.

All reference guides, along with a short description, can be found in this document: TMS320x28xx, 28xxx DSP Peripherals Reference Guide (www.ti.com/lit/SPRU566).

I've also added this question to the GPIO FAQ page: http://processors.wiki.ti.com/index.php/General_Purpose_IO_(GPIO)_FAQ_for_C2000
