Hello,

Could anyone tell me how to configure conversion time of ADC at 0.5ms using HALCOGEN.

Thank You Bob.

Could you please explain how the cycle time affects the adc conversion time.

The ADC cycle time is the period of the ADC clock. The conversion time is one ADC clock for each bit of conversion. For 12-bit accuracy the conversion time is 12 ADC clocks.

Hi Bob,
Just curious, how much time is there between two conversions on the same ADC group or on different groups?
