STEVAL-IAS001V1 Security keypad based on ST7FLite39 and STM1403
This demonstration boards offers the functionality of a keypad controller in security door applications. The aim of this board is to assist in the development of a keypad decoding system and to display associated information through LEDs for all necessary actions such as power on, door open and error. The entire system has been developed to target low-end and low-cost application areas and has been realized with the help of the ST7LITE39F2 microcontroller. A useful additional feature is the support of system protection from physical intrusion, using the STM1403. STEVAL-IAS001V1 aims to display the capabilities of ST's general purpose microcontroller to fit the market segment of home automation and security, keeping the system cost as low as possible. The board can operate in 2 modes:
- Administrator mode
- through PC graphical user interface
When the board is connected to the power supply the system enters the user configuration mode.
Administrator mode can be accessed through the use of a PC, where SCI communication is set up and used between the PC and the board through the RS232. At the time of manufacturing an additional board has been connected to allow incircuit programming of the microcontroller. The two boards can be easily disconnected so that the keypad controller for the security door evaluation board can be used independently
