Hi all, I have made this request before my article combination lock circuit. As you know, on the internet, various controllers (atmel, pic, etc.) are made with a lot of combination lock implementation. When the implementation of a simple combination lock, similar to me. As the application’s main feature is that it is made of a printed circuit board. In addition to this, due to a design, just 3/4 pieces on a cable you can program and debug the circuit using the msp430′a. In addition, during the study and use of flash memory with the msp430 keypad, write, read operations are functions that might be an example.

MSP430 Design with Combination Lock

As we commonly use MSP430 Launchpad with various MSP430 applications can do by connecting additional equipment . In addition to this, we develop a product , or an assignment, project , etc. needed to make printed circuit boards is inevitable. Compared to other MSP430 microcontroller on the Internet by none so much pressure circuit applications . That’s why I felt the need to share this application due .

Each microcontroller due to a few differences in the structural design of printed circuit boards can vary . For example, the most important element for MSP430 programming circuit and the supply voltage is 3.3V . Other microcontrollers made ​​by paying attention to them MSP430 applications in printing circuit can be implemented. This , above all, those described printed circuit design and PCB drawings are required to be knowledgeable about the program . This application of the printed circuit Proteus / Area program ( v7.7 ) is designed with .
