topic going to sleep in LPCXpresso IDE https://community.nxp.com/t5/LPCXpresso-IDE/going-to-sleep/m-p/567399#M18863 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by mayotte1 on Fri Apr 09 10:04:56 MST 2010</STRONG><BR /><SPAN>My project is working so well now that I need to have it start sleeping. I don't really find much info on the _WFI that is used in the blinky example. The comments in the blinky code say it is going to sleep to save power but the discussions on the forum seem to indicate I need to do more than just issue a _WFI. I do see on the scope where the project is waiting but cannot really tell if any reduced power is in play.&nbsp; Any comment would be appreciated. Thanks in advance.</SPAN></BODY></HTML> Thu, 16 Jun 2016 02:19:32 GMT lpcware 2016-06-16T02:19:32Z going to sleep https://community.nxp.com/t5/LPCXpresso-IDE/going-to-sleep/m-p/567399#M18863 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by mayotte1 on Fri Apr 09 10:04:56 MST 2010</STRONG><BR /><SPAN>My project is working so well now that I need to have it start sleeping.

It makes CPU stop executing and go to sleep until it gets an interrupt. Which sleep mode is entered depends on the power configuration. See "Power control" in your chip's user manual.</SPAN></BODY></HTML> Thu, 16 Jun 2016 02:19:33 GMT https://community.nxp.com/t5/LPCXpresso-IDE/going-to-sleep/m-p/567400#M18864 lpcware 2016-06-16T02:19:33Z
