Hello,

I'm using IIR project from C:\ti\c2000\C2000Ware_4_02_00_00\libraries\dsp\FPU\c28\examples\filter\iir_f32

while single stepping it gets stuck at Error or done flag check. why program is not moving forward?

also want to see data of ip and op on graphs.

Hello Anshuman,

It looks like you mention the F28335 in your post, but the sysctl.c file that you're stepping through is not for this device. Can you clarify which device you are running this example on?

Best regards,

Omer Amir

Thanks Amir,

i'm using TMS320F28335 as mentioned. Please suggest appropriate IIR filter (floating point) for the same.

Hello Anshuman,

You can continue to use this example and the same filter, you just need to change all the project properties such that the F2833x drivers, etc. are selected. Let me know if you need help configuring this.

Best regards,

Omer Amir
