Using two LPCOMP channels simultaneously

[Nikolaj]

Hi,

Is it possible to use two LPCOMPs simultaneously?

I would like to use analog channel 6 and 5 and if I register a RESULT Above on channel 6 it should start a software timer, if it register a RESULT Above on channel 5 it should start another software timer.

Is this possible?

Unfortunately, there is only one LPCOMP peripheral on the chip, so that will not work. You can however constantly change the PSEL register to switch between two input pins.

hi :) 

how can i change the selected pin ? 

do i need to stop / disable the LPCOMP -> change pin -> AND THEN START IT AGAIN ? 

can i reconfigure the referance v and the raising or falling  as well in each pin change ?

best regards
