wrLCDcom: clr LCD_EN clr LCD_RS ; select send Command mov LCD_DATA, r0 ; load command into port lcall pulseEwait ; pulse the Enable line ret pulseEwait:clr LCD_EN setb LCD_EN ; pulse the Enable line clr LCD_EN mov LCD_DATA, #0ffh ; prepare port for input LCALL DELAY_5_1MS ; delay LCALL DELAY_5_1MS ; delay ret This is the routine that sends commands to the LCD such as clear screen, move cursor, shift screen, blink cursor, etc. and 'R0' is what I'm using as the register whenever I write to the LCD. Indeed I had pushed and poped the ACC during the UART interrupt, but I keep changin the code I didn't put it back in there. See, I can generate a serial interrupt without any issues, but I cant seem to get a consistent value each time I scan a card. I have tried changing it to ASCII by adding 30, I've tried to strip of the data, etc., but still No SUCCESS. |

| Just the 'integral part' Part of code | 01/01/70 00:00 | |
| you still did not tell the derivative | 01/01/70 00:00 | |

| is DELAY_5_1MS timer based? | 01/01/70 00:00 | |
| Yes DELAY_5_1MS is timer based | 01/01/70 00:00 | |
| so, you call one device generating an interrupt fr | 01/01/70 00:00 | |
| Already tried that | 01/01/70 00:00 | |
| then keep it that way | 01/01/70 00:00 | |
| Here's the entire code.... | 01/01/70 00:00 | |
I quick look, not an analysis | 01/01/70 00:00 | |
| Have a look at this | 01/01/70 00:00 | |
