PASSWORD CODE AND 4X4 KEYPAD CCODE

I am using PIC16F877 to implement communication with a PC. I want a code in C language to execute the following tasks:

(1) To password it to prevent unauthorized access.
(2) To use a key on the 4x4 keypad to display more than one character. For example, key 1 to able display Number "1" and Letter "E", "F" and "G".

I need the code in C language to execute the two task above.

PROBLEM ON CODE OF GSM CONTROLLING APPLIANCES THROUGH SMS

Dear members I have a problem, I have prepared the code of GSM CONTROLLING APPLIANCES THROUGH SMS and when I compile it no any error comes after compiling and when i tested it on proteus using PIC16F877A all lights are turned on initially and always remain on until i stopped a simulation. Any one who can collect my code please can help me.. Below it's my code the code was compiled in MikroC for PIC.

stm32l4 discovery board USB and I2S

Hi

i have discovery board of stm32l476VG ( www.st.com/stm32l4-discovery ).
but mikroC cant support USB for this board, so mikroC have not any solution to use I2S of this board.
this board have a 43L22 I2S codec of CIRRUS company.
i cant find any source code or library for it.
if anyone have any source code , please help me.

Regards.
