Hi everyone, I need to draw a flowchart from a software of a PIC16F84 based Simple combination lock, can someone tells me how does the program works? I’m really time short and I’ve read the PIC’s datasheet for 3 days and still cant understand the software, I didn’t even know what EQU is for…. It is due for the day after tomorrow, I don’t have enough time now… help ASAP please, SOS… :cry: :cry:
there are some mistakes on the schematic, which is the Vss should be Grounded and Vdd should be on +5. and RA0 should be connected to switch 4, and RA5 if not used should be Gnd
Sorry, but we're not here to do your homework for you :cry:
That particular diagram has been discussed here previously, it's particularly hard to understand. There's a simple code lock in my pic tutorials at http://www.winpicprog.co.uk which uses a 16F628, hex keypad, and LCD - it's under the keypad section, the code should be much easier to understand.
