SX1507/SX1508/SX1509
World’s Lowest Voltage Level Shifting GPIO
with LED Driver and Keypad Engine
4.9.7
Tutorial
Below are the steps required to use the LED driver with the typical LED connection described §6.2:
-
Disable input buffer (RegInputDisable)
-
Disable pull-up (RegPullUp)
-
Enable open drain (RegOpenDrain)
-
Set direction to output (RegDir) – by default RegData is set high => LED OFF
-
Enable oscillator (RegClock)
-
Configure LED driver clock and mode if relevant (RegMisc)
-
Enable LED driver operation (RegLEDDriverEnable)
-
Configure LED driver parameters (RegTOn, RegIOn, RegOff, RegTRise, RegTFall)
-
Set RegData bit low => LED driver started
