    LCD interface for PIC18F4550 problem

    added #pragma config PLLDIV = 5 #pragma config CPUDIV = OSC1_PLL2 #pragma config USBDIV = 2 #pragma config FOSC = HSPLL_HS but still its not working. is there any other register which I should set (eg. CMCON1) for using PORTE/D? - - - Updated - - - changed lcd_ini() as follows: void lcd_ini()...

    [SOLVED] PIC18F4550 USART protocol

    Hi, I have written this code to check out USART protocol on PIC18F4550 (44-pin). Tx and Rx are shorted with wire. The LED connected to RB3 and ground should go off when the data is transmitted. It is not at all working. Please help in debugging. #include <p18f4550.h> #define baud 9600 #define...

    Code for scanning 4x4 hex keypad in verilog- Not working

    I have adapted it from keypad datasheet. This is written just to see if I can interface it. While checking I am pressing only single key till i get stable output, so debouncing and whether to accept single or multiple can be worked out later. I have tried to make always@() work on clock pulse...
