4182E–CAN–05/04
An interrupt end-of-conversion will occurs when the bit ADEOC is activated and the bit
EADC is set. For re-arming the interrupt the bit ADEOC must be cleared by software.
Figure 72. ADC Interrupt Structure
1. Configure P1.2 and P1.3 in ADC channels
2. Start a standard conversion
3. Start a precision conversion (need interrupt ADC)
Note:
// configure channel P1.2 and P1.3 for ADC
// Enable the ADC
// The variable "channel" contains the channel to convert
// The variable "value_converted" is an unsigned int
// Clear the field SCH[2:0]
// Select channel
// Start conversion in standard mode
// Wait flag End of conversion
// Clear the End of conversion flag
// read the value
// The variable "channel" contains the channel to convert
// Enable ADC
// clear the field SCH[2:0]
// Select the channel
// Start conversion in precision mode
