During sleep GPIO

Everybody is good!

We use GPIO driver two leds, we now can only when DA14586 than low power LED light, entered into a state of low power LED is not lit, what method can let GPIO after into low power consumption is still keeping the original state?

When we use P1_2 and P1_3, LED anode GPIO, LED cathode grounding.

Thank you very much!

hello

hello

After entering the low power consumption IO power supply is cut off.

Relative to the LED lights several mA current, in fact the CPU power consumption is only about 100 ua, whether can consider not enabled when he worked in LED low power?

Hi Libing,

Hi Libing,

As CYiBin advice, your LED should not be directly driven by the GPIO DA14586 anode, can adjust the LED circuit makes the GPIO into dormancy driven by external power leds.
