Find help, specifications and source code for the LPC900. The LPC900 challenges Microchip and AVR based on the worlds most popular 8-bit architecture the 80C51. With a 2-clock core the LPC900 series is a high performance, very flexible and low cost 8-bit microcontroller family. Designers using or interested in these devices are encouraged to share their know-how and ask questions.
Application Hint LPC900 family ADC #2 "boundaries" - philips_apps - Aug 9 14:05:00 2004
Hi,
the ADC offers many innovative features, this is a little hint for
another nice one.
The ADC has boundary registers. This means that you can have the ADC
convert in the background and absolutely don't care unless a critical
value, the "boundary" has been reached. This is using the ADC as a
comparator and may be considered a waste of an ADC channel by some of
you. However, the implementation supports the function of a
"window-comparator" while the conversion results are within a
preprogrammed target range, there will be no interrupt at all, as soon
as e.g. a temperature reaches the "too hot" or the "too cold" range,
the program will be interrupted and can take appropriate actions.
It is fun using the nice features of the LPC900!
