With this exercise we will learn to read and write in an EEPROM (25LC020) through SPI communication with the PIC 18F4550.
The exercise consists of the following:
To start writing the program code in C language for PIC's of CCS. The PIC is programmed as a master at using the SPI BUS. The first thing is to write, in this case write 7 data, from 0 × 00 to 0 × 07. Amedida that are written to the EEPROM is written to the LCD every half second, the first E stands for writing. Once written, we will read and display them as Ian is displayed on the LCD every half second. The L is read
To test the operation load the program on the Proteus and simulate. Using a tool you can view all transfers made by the SPI. In the simulation is seen as the PIC reads the data recorded in the EEPROM as the LED goes from 0 to 6.
