Hi,

i want to read the uid of the processor. (LPC11U67/LPC11U68) The UM10398 describes the function "ReadUID", but my compiler doesn't find this function. Where can i find this function?

Thanks in advance,

Marcel

I'm using the arm-none-eabi-gcc ( version 4.8.4 20140725) from the lpcexpresso v7.5.0  ide.



LPCOpen 2.06 for LPCXpresso LPC11U68 board is including an IAP sample:

periph_flashiap_flashsig

Just add there ReadUID (IAP58) = write command 58 and read 4 result words  :)

The READUID command can be accomplished using IAP or ISP.
I am assuming that you would like to use IAP.  Examples how to use IAP can be found at:

Read section 26.7 ("IAP Commands") of UM10398 which tells you how to use IAP to read the UID and all of the other IAP functions

ReadUID is an ISP / IAP command  :O

Don't know which 'compiler' you are using, but it could be useful to look for an IAP sample...
