Digital code lock using 12F629
Hi,
I found this simple code lock for my alarm project.
Security Keypad. This Electronic Code Lock uses a 12-keys keypad is used to enter a password and open an electrick lock or any other device with a signal. Uses an 8-pin PIC 12F629. (11/17/2004)
Works fine but the LED glows dim during standby!!!
Any idea from PIC experts would be appreciated:-)
Dear Nigel Goodwin,
I am novice to pic, help me to sort this problem out of my project.
My efforts to rectify this by anything is not worked.
Reduce the 1K resistor to 220 ohms.
BINGOIt's working.
But power consumption on standby is 1.2 mA which is high for my battery operated project.
Any modification on hex code would possible to solve this problem?
Slow down the internal osc or put it to sleep.
BINGO

Do you have the source code?
He using a hex he down loaded from the site I say he didn't disassemble But if he did I hope he will post the code. I look at it last night and tried disassembling it it's big take some time to do. I imported to mplab I no there got to be a better way then that to disassemble.
Hex code can be download here http://josepino.com/pic_projects/sec...pad/JP6296.hex

You said the "power consumption on standby is 1.2 mA" is this with the LED on?
It is hard to adjust the disassembled code.Better use high capacity NIMH cells.
No, Actually the LED is off during standby but glows when a key pressed.

The watchdog is also off
And it's hard to add that to hexwatchdog

Can't tune more than that.disabling built in modules doesn't make such a big different.
Try adding 330ohms resistors to pins 5,6,7 & see.I don't know much about joepinos technic regarding where the GND path follows for the switches?
Hi, Let me check your idea then I will PM here
