TMS570LS3137-EP: Toggle HET pin

Other Parts Discussed in Thread: HALCOGEN

Hi,

In rtiBlinky example on HalCoGen, the code gioSetPort(hetPORT1, gioGetPort(hetPORT1) ^ 0x0000001); is used to toggle HET pin 0.

What is the value to toggle other HET pins? Where do I find that information?

Many thanks,

Shiromini,

I believe you can simply change the xor bit location to different bit in the hetPORT1. For example toggle het pin 1 with ^ 0x0000002

There is training material here:
training.ti.com/.../EN

I will take a look to confirm the above.

Regards,
Wade

Shiromini,
You can see how the coding works by changing the bit weights in HalCoGen and then rewriting the code and comparing the values in het.c.
For example, you can change the DOUT value, or DIR, or PDR values for any of the 0-31 bits and see the settings change in the het.c after generating code. Hopefully this will resolve how to set these registers.

Hi Wade,

How do I change the values? Can you post a screen shot to show please?

Many thanks,

Shiromini,
Were you able to figure this out yourself?
I don't have a hardware setup available to test right now, but I can get one if you still need help.
