Figure 8-11 4-wire SPI Timing Diagram• EEPROM ControlEEPROM is accessed through the I2C interface. In this demo, I2C signal is toggle by NIOS IIthrough the PIO controller. The I2C clock signal is driver by an OUTPUT PIO Controller and theI2C data signal is driver by a BIDIRECTION PIO Controller. The I2C C code is located in:DE0_NANO_SOPC_DEMO\software\DE0_NANO\terasic_lib\I2C.c• EPCS ControlEPCS64 is accessed through the EPCS interface. In Quartus 10.0 or later, the EPCS pin assignmentis required and should be connected the pins to EPCS Controller as shown below Figure 8-12:Figure 8-12 EPCS interface connectionFor the EPCS access functions, users can refer to:DE0_NANO_SOPC_DEMO\software\DE0_NANO\terasic_lib\Flash.c138
Demonstration Source Code• Project directory: DE0_NANO_SOPC_DEMO• Bit stream used: DE0_NANO.sof• NIOS II elf file: DE0_NANO.elfDemonstration Batch File• Demo Batch File Folder: DE0_NANO_SOPC_DEMO\demo_batchThe demo batch file includes the file:• Batch File: test.bat and test_bashrc• FPGA Configure File: DE0_NANO.sof• Nios II Program: DE0_NANO.elfDemonstration Setup• Make sure Quartus II and Nios II are installed on your PC.• Connect a USB cable to the DE0-Nano board and install USB Blaster driver if necessary.• Execute the demo batch file “test.bat” under the batch file folder,DE0_NANO_SOPC_DEMO\demo_batch. This will load the demo into the FPGA.• After executing the batch file, a selection menu appears as follows:• Input “0” to start the accelerometer demo. The demo starts by displaying the accelerometer’schip ID, and then continues by displaying the X/Y/Z values every 1.0 second. Toterminate the demo, press KEY0 or KEY1 on the DE0-Nano board. Upon exiting thedemo, the selection menu will be displayed.139
