Note Observe that the total Code bytes of the hid_kb project is less than the 4-k code limit of Keil
uVision2 IDE provided along with the kit.
■ Firmware for EZ-USB RAM memory: The output of the Build Target is hid_kb.hex. It is the rel-
evant file for downloading to EZ-USB RAM memory.
■ Firmware for external I2C EEPROM: To generate EEPROM compatible firmware image, the
Keil IDE invokes the hex2bix.exe utility to convert the output file hid_kb.hex into hid_kb.iic.
Right-click on Target1 in the Project Window and select Options for Target 'Target1'. This will
pop-up the Keil settings for this project. Select the Output tab and observe at the bottom of the
IDE, the hex2bix utility is invoked as shown in Figure 8-3.
