CCS/TMS320F28335: Obtaining Output at Oscilloscope

RATIK MITTAL
Prodigy 170 points

Part Number: TMS320F28335
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hello,

I'm using TMS320F28335  and trying Multi-Day workshop lab exercise ( Lab 8). Lab 8 is performing FIR on an input signal at ADCA0. I want to see the  output,whatever that is being stored in "AdcBufFiltered" register,  on an oscilloscope. I was wondering if someone can tell how to configure GPIO.c file using CCS.

Regards

Ratik

    Ratik,

    Lab 6 of the multi-day workshop shows how to setup a GPIO as an output using the GPOI.c file. Follow that as a guide. Additionally, there are GPIO example included in C2000Ware as well.

    I want to be clear that setting up a GPIO will only enable Digital outputs, these are only capable of outputting a logic 0 or a logic 1. If that works for your purpose, great! But, they do not function as a DAC and can only output 0v or 3.3v. 

    Note: You can implement a DAC using a PWM though.
