Other Parts Discussed in Thread: CC3220SF
Hi,
I am working to send the raw data from C2000 to CC3220SF. When we give a sinusoid input (0-2V) to ADC of C2000 based on PWM triggered sampling frequency, we are able to send the raw data to cc3220sf successfully while we are performing 64Point FFT on the ADC data (64 samples/cycle) simultaneously . Here the strange thing come when we try to generate harmonics (consider an arc in a power circuit as signal containing harmonics) signal at the input of adc and send the harmonized raw data to SPI. SPI starts sending all data as 0xFFFF (from c2000 to cc3220sf) and CC3220SF clock continue even after receiving the intended size (ex. Rx Count at cc3220sf is 256 but it will continuous to receive 0xFFFF even after that.
What can be the issue, is it hardware or something else ?
Thank you.
Best Regards,
Kuldeep
