Part Number: F28377D-SEP
Other Parts Discussed in Thread: LAUNCHXL-F28379D
Hi,everyone!
1.In LAUNCHXL-F28379D, when I sample the current sensor with the ADC, the measured results always have significant abnormal interference (out of a hundred points sampled, there will be one point with an error of nearly 0.045V). Could it be a problem with my software configuration? The voltage data of the AD interface was measured with other precision instruments. (The measured current value was normal, which can prove that the voltage signal of the current sensor is fine. )
2. If I want to use an off-chip ADC to reduce interference, could you recommend a solution for me? Here are my work requirements:
a) I need to collect 5 current data points.
b) My interrupt time is 10kHz. To leave some running time for other algorithms, the communication time between the off-chip ADC and dsp needs to be within 50 seconds.
Thank you for taking the time and effort to watch this issue!
