Other Parts Discussed in Thread: TMS570LS3137
Hello,
Can I ask your advice to implement a diagnostic for ADC MUX(multiplexer) ?
We would be glad if you could comment for hardware and software.
- Hardware: In case of Hercules (TMS570LS3137), 16 terminals are connected to both ADC1/2 and the duplicated readings can be compared. I think such duplicated ADC paths are not there in the F28377D. How TI has implemented a diagnostic on the F28377D to pass the IEC61508 SIL-3?
- Software: Is there a sample code to self-test the MUX? It would be like, many calls to the STL_ADC_test() in various MUX conifguration.
My point is not the ADC but the MUX.
I have downloaded the C2000-DIAGNOSTIC-SW-PACKAGE and found the STL_ADC_test() is a good solution for the ADC body or a single channel.
