Other Parts Discussed in Thread: THS4031
we have some problems with ADC's. The simplest description of this problem is that we see sampled values that are repeated, despite of the fact that the applied signal has not the values that should lead to this repetition
Example:
applied signal ( programmed arbitrary signal with wave form generator)
example:
signal sampled value
1.23V 956
1.56V 1245
1.97V 1245
2.15V 2049
2.78V 3045
and so on.
this repetion is not periodicaly and is not depending on sampling frequency. SOC Signals and EOC Signals were observed with oszilloskop and are correct. Same behavior can be observed using v220\F28M36x_examples_Control\epwm_adc_soc example from control suite.
For me it's looks like the conversion isn't ready although the EOC and Interrupt are generated or SOC Signal is not recieved although the SOC Signal is generated.
thank for your reply...
Kind regards,
