I have been assigned a task to make an EEPROM interfacing library in keil uvision 5for the same. the question is that in the pdf of LPC17xx it shows no hits for the keyword "eeprom" , does it have one? And if not then I have to use an external IC? Can someone help me out with the library?</P></BODY></HTML> Sun, 12 Jun 2016 10:40:39 GMT jwalinthaker 2016-06-12T10:40:39Z LPC1769 - Interfacing EEPROM https://community.nxp.com/t5/LPC-Microcontrollers/LPC1769-Interfacing-EEPROM/m-p/518850#M2883 <HTML><HEAD></HEAD><BODY><P>Hello, </P><P>I am using an LPC1769 microcontroller on a self-designed board whoch is only for general I/O and UART comm.
