ADC Config for F280X – early versions

The ADC Config dialog is dependent on the target you select. If you selected a newer device, the dialog box parameters are different from the ones shown below.

ADCCLK: Specifies the analog-to-digital converter clock.

Sample Duration: Chooses the number of ADC clock ticks for a given ADC sample. High impedance inputs require longer samples. A recommended duration is 20 nsec.

HCLK: Specifies the high-speed clock.

Sample Duration: Chooses the number of ADC clock ticks for a given ADC sample. High impedance inputs require longer samples. A recommended duration is 20 nsec.

Sample Trigger

Controls when to start sampling channels.

Cascade Sequence 1 and 2: Scans sequence 1 followed by sequence 2.
Sample Sequence 1 and 2 at the same time: Allows the simultaneous sampling of the two sequences.

SYSCLK: Indicates the speed of the CPU clock 

Use Continuous Conversion: Enables the continuous conversion option in the hardware.

Use Full Scale Value = 1: Provides direct read of the ADC result register with no scaling. When activated, the value will range from 0 – 0.00007. When de-activated, Embed adds code to scale the result from 0 – 3.
