Software SPI

0

Bit Banged SPI using PIC 16F877A Micro-controller unit (MCU) implemented in Mplab X IDE. The MCU writes data to particular addresses of a 25LC256 EEPROM device, and reads back the data by only passing address information to the EEPROM. This data is then displayed on a common-Annode 7-segment display connected to a port on the MCU.
