The key without any identity data before perform unlock operation. Inside the key will have a PIC12F629, a Voice IC, and a Voltage Regulater IC (battery). It will have 3 device: Cradle, Key, and Lock (1 Key to many Lock).Ĭradle is a middle man that help the Software System (PC) and key to communicate.Ĭradle connect to PC via USB, more the 1 key are slot in to a cradle. My project is a electronic key+lock system. So, is better not to code protect if i want to access the data? Is it possible to program the PIC12F629 to output the data instead of access it's data? Or, should i use any other method to encrypt the data, kindly suggest.
Have you guys try to get some loan set from Microchip before? Kindly suggest what tools/programmer/debugger/simulator/emulator to is suitable for PIC12F629. Does it means the log will be erased too? Is it possible to recover the data memory, just to pull back the log. As i know, if we try to disable the code protection bit, the PIC12F629 will erase everything. Is there a clock (date & time) inside the PIC12F629? So that it can record down when and what action did. One of the requirement is to do audit log. My question is, is there any way to access the data/program after it has been protected? Does it have something like password to unlock?ģ) Possible to do audit log (date & time)?

Is it possible to write program in C#?Īny website that provide free sample/tutorial for microchip programming?Ģ) How to access data after code-protected?īased on my understanding, PIC12F629 support code-protection, it can code protect the program memory and data memory. I'm not familiar with C, i have zero knowledge in assembly. I have few questions that i need your help on.
I'm new to microchip and i do not have assembly language background, i have been assigned to a project that need to program PIC12F629.
