Blink LED, and sample from ADC using GPT interrupt on C5535 DSP

Other Parts Discussed in Thread: TMS320C5535, TMS320C5515

Hi All,

I need help. I have the C5535 ezdsp board and I'm trying to set it up to do a simple task. I only have experience of programming a MSP430 using GRACE, so I am baffled by this thing.

All I want to do, to start with, is flash one of the LED's, and sample from the ADC all triggered by an interrupt from the GPT.

I have played around with the examples in CCS but can't figure out how to do this. I have searched and searched for a simple example of blinking an LED on a timer interrupt, but there's none.

I realise using a DSP for such a simple task is over kill, but humour me.

Any help would be greatly appreciated.

But, please don't tell me to download the C55 Chip support libraries... I have already looked at those examples, they are just a collection of letters and numbers to me!
