7.3.2
A/D converter interrupt processing
When 10 converted data values are written to the FIFO buffer, an A/D interrupt is
generated so that interrupt processing can take place. The interrupt processing routine
fetches 10 A/D conversions from the FIFO buffer, and averages them. This is treated as the
acquired value (value used to determine humidity) from the humidity sensor. The figure
below shows the details of the A/D converter interrupt processing routine.
A/D converter interrupt processing
- Stop A/D converter
- Clear interrupt causing bit
Get 10 A/D conversion results from FIFO
Calculate average (ad_average) from A/D
conversion results
Clear FIFO
