These are set up in the [FONT=Courier New][SIZE=2]system_LPC[I]nn[/I]xx.c[/SIZE][/FONT] file (replace [FONT=Courier New][SIZE=2][I]nn[/I][/SIZE][/FONT] with part number) within the appropriate CMSIS library project.</SPAN><BR /><BR /><SPAN>If you access the[FONT=Courier New][SIZE=2] SystemCoreClock[/SIZE][/FONT] variable within your code base, then you can see what clock speed has been set up. [Note that if you don't actually reference SystemCoreClock from your code, the linker will normally remove it from the final image - so you won't then be able to see it within the debugger.]</SPAN><BR /><BR /><SPAN>If you want to change clock speeds, then I would advise using the PLL spreadsheet NXP have available:</SPAN><BR /><BR /><SPAN>LPC17...</SPAN><BR /><A href="http://">http://ics.nxp.com/support/documents/microcontrollers/xls/lpc17xx.pll.calculator.xls</A><BR /><BR /><SPAN>LPC11...</SPAN><BR /><A href="http://">http://knowledgebase.nxp.com/showthread.php?t=337</A><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>CodeRedSupport.</SPAN></BODY></HTML> Wed, 15 Jun 2016 22:05:55 GMT https://community.nxp.com/t5/LPCXpresso-IDE/Maximum-Allowable-Torquage/m-p/549999#M11225 lpcware 2016-06-15T22:05:55Z Re: Maximum Allowable Torquage? https://community.nxp.com/t5/LPCXpresso-IDE/Maximum-Allowable-Torquage/m-p/550000#M11226 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by woodchuck on Tue Aug 03 13:14:00 MST 2010</STRONG><BR /><SPAN>Perfect!&nbsp; Many thanks.</SPAN></BODY></HTML> Wed, 15 Jun 2016 22:05:56 GMT https://community.nxp.com/t5/LPCXpresso-IDE/Maximum-Allowable-Torquage/m-p/550000#M11226 lpcware 2016-06-15T22:05:56Z
