ADC input as wake up source

Hi,

Please let me know, whether kinetis and LPC micro-controller has ADC input as wake-up source from deep sleep mode(Low power mode).

Regards,

Vineeth

Hi Vineeth113 754,

It determined by which mode and chip you are using.

1. the kinetis chip:

As you know, the stop and VLPS can be waked up by the interrupt, then you just need to check whether the ADC module can work or not in the according low power mode.

So, if the ADC can work in the according low power mode, and that low power mode can be waked up by the interrupt, then enable the ADC interrupt, after the conversion is finished, the interrupt happens will wake up the according mode.

2. LPC chip

Take LPC5411x as an example.

No ADC wake up in the deep sleep mode.

Wish it helps you!

Have a great day,
Kerry
