Content originally posted in LPCWare by sumit.kajave on Wed Jul 29 05:11:24 MST 2015I developed LPC2387 board by own for my home automation project. I burn my IC using flashmagic. In my code I select ROM at address @0x2000 location. My software run on internal oscillator. I developed my code by help of sample code bundle for LPC2300. My PLL section as below #define PLL_MValue35#define PLL_NValue0#define CCLKDivValue23/* System configuration: Fosc, Fcclk, Fcco, Fpclk must be defined *//* PLL input Crystal frequence range 4KHz~20MHz. */#define Fosc4000000/* System frequence,should be less than 72MHz. */#define Fcclk12000000#define Fcco288000000 I am using keil uvision5 IDE for my development. In simulation my code running properly. But on my board my code doesn't work. I simply toggle port 0. I attach my code below.Original Attachment has been moved to: lpc_lcd.rar
