    4-bit mode of LCD-1602 using 8052 µc

    I try writing "NO" in the LCD using 4-bit mode. So, I programmed the AT89S52 to send the upper nibble first to the last 4 data inputs of the LCD. I used AND operation to eliminate the lower nibble. Afterwards, I cleared the RS bit and send a HIGH-TO-LOW enable pulse. The same code for the lower...

    This simple PIC24 assembly code doesn't execute. I don't know why.

    After much grief getting assembly code to compile and download on MPLAB-X, I have everything I ever dreamed of, but this dream turned into something less than I expected. For reasons unknown to me, this simple LED flash code doesn't seem to execute. It does simulate OK in MPLAB V8.xx The two...
