MAX5970 Evaluation Kit
The MAX5970 has four open-drain LED driver pins that
double as user-programmable GPIOs. Place shunts
across the 1-2 position of jumpers JU7–JU10 and control
the individual LED from the checkboxes (SET, FLASH,
WEAK PULLUP, and FLASH PHASE) within the LEDs
group box. The user can also set the LED driver pin as a
GPIO by placing a shunt in the 2-3 position on jumpers
JU7–JU10 and selecting the Options | GPIO menu item.
There are two methods for communicating with the
MAX5970, through the normal user-interface main
window, or through the I²C commands available by
Figure 4. Example of an SMBusReadByte Operation Using the Advanced User Interface

Advanced User Interface
LEDs and GPIOs
selecting the Options | Interface (Advanced Users)
menu item. An Advanced User Interface window pops
up with the 2-wire interface tab selected, which allows
the SMBusK/I²C-compatible protocols, such as read
byte and write byte, to be executed. The only SMBus/I²C
compatible protocols used by the MAX5970 are:
The combo and edit boxes accept numeric data in hexa-
decimal and should be prefixed by 0x. See Figure 4 for
an example of this tool.
