Register View
The contents of the Port Configuration Registers;
Output Intensity Registers; Blink Phase Registers;
Master, O16; and Configuration registers can be moni-
tored by opening the Register View window, which is
accessible by selecting the View | Register View menu
item. Refer to the MAX7313 IC data sheet for additional
register information.
LED Demo
The LED Demo button provided on the software’s main
window provides a demonstration of the EV kit’s opera-
tion. Pressing the LED Demo button results in the
WLEDs and RGBs performing a sequence of blinks,
demonstrating the LED control capabilities of the
MAX7313 device.
General-Purpose 2-Wire Interface Utility
The general-purpose 2-wire interface utility can also
be used to communicate with the MAX7313. Use the
View | Interface menu item to access the utility. The
utility configures the 2-wire serial interface parameters,
such as start and stop bits, acknowledgements, and
clock timing. The 2-wire interface screen allows gener-
al-purpose 2-wire commands to be sent using the
SMBusWriteByte and SMBusReadByte options. The
interface utility only accepts and outputs hexadecimal
number format.
The Hunt for active listeners button scans the entire
2-wire address space, reporting each address that is
acknowledged. The SMBusWriteByte transmits the
device address, command, and one byte of data. The
SMBusReadByte transmits the device address, a com-
mand, and then retransmits the device address and
reads one byte of data.
