MAX7313 Evaluation Kit
The MAX7313 can be returned to its power-on-reset
(POR) state by selecting File | Reset from the menu
bar. After a reset has been performed, ports P0–P11
are configured as inputs. This is reflected on the soft-
ware’s Port Configuration and Port Status tabs.
Although the P0–P11 ports are configured as inputs on
reset, the EV kit is designed to operate with P0–P11 as
output-only ports. Pressing the Configure button on the
Port Configuration tab configures the P0–P11 ports as
outputs. Refer to the MAX7313 IC data sheet for details
on the device’s power-up configuration.
The Global and White LED Config/Status tab contains
two group boxes. The Global Configuration/ Status
group box is used to enable/disable various MAX7313
global functions. The White LED/Flash Configuration
group box is used to configure the WLED output ports,
as well as provide flash capability. See the Global
Configuration/Status and White LED/Flash Configuration
sections for details on each group box’s controls.
The Global Configuration/Status group box provides
controls to configure global device settings: blink
enable, blink, and LED intensity control. The Static
Outputs and Global Intensity Control checkboxes are
used to set the desired LED intensity control scheme.
The Master Intensity and Global Intensity track bars
are used to configure the desired LED intensity. See
Table 2 for details on configuring the device for one of
Table 1. Initial Configuration
* See the Global Configuration/Status section.

the three intensity control schemes. When configured
for static and PWM outputs, see the White LED/Flash
Configuration and RGB LED Config/Status sections for
more details. Refer to the MAX7313 IC data sheet for
additional LED intensity control details.
The White LED/Flash Configuration section is used to
turn the EV kit’s WLEDs (D5–D8) on and off, adjust
WLED intensity, and provide control of all four WLEDs
as a single flash unit. The Phase 0 and Phase 1 check-
boxes are used to set or clear the respective bit in that
blink phase register. When checked, the associated
output port is set low, turning the respective WLED on.
When unchecked, the associated output port is high
impedance. The WLED Intensity track bar indepen-
dently controls the intensity of all WLEDs (D5–D8).
Refer to the MAX7313 IC data sheet for additional inten-
sity setting details.
Flash features such as Single Flash, Repeat Flash,
and time delays from 0.5s to 8s duration can be select-
ed. To utilize the flash feature, the Enable Flash Timer
checkbox must be checked. Pressing the Run Flash
button initiates the flash sequence. The Single Flash,
Repeat Flash, and flash timer settings can be changed
on the fly. When running the flash, all global BLINK
checkboxes are unchecked and all white LED check-
boxes are disabled. To stop the flash sequence press
the Stop Flash button, and to disable the flash feature,
uncheck the Enable Flash Timer checkbox.
Warning: Do not continuously stare at LEDs.
