(a) Introduction In this laboratory experiment, our objective is to establish an interface between two 7- segment displays, along with their respective decoders (7447/7448), and an EEPROM (2864). The aim is to create a counter that ranges from 0 to 15, which will then be visually displayed on the 7-segment displays. However, conventional binary counting from 0000 to 1111 cannot be directly showcased on a single 7-segment display. To overcome this limitation, we must convert the binary values into two Binary-Coded Decimal (BCD) digits, enabling them to be accurately presented on the two 7-segment displays. This conversion is necessary because the decoders (specifically the 7447/7448) are designed to handle binary data up to 9 (1001). ■ To achieve this, we will utilize an EEPROM to store the BCD representations of the numbers we want to display. These BCD values will be stored in memory, and we will access their locations using the address bus. An asynchronous up counter will be employed to increment from 0 to 15 (0000 to 1111), and the corresponding BCD representation of each number will be retrieved from the output data bus (D7-D0) to display on the 7-segment displays.
