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:

Please view the page and software here

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

Thank You very very much…

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.
