MKL LOW POWER WITH TSI.

[eliezeroc]

Hello. I'm developing a project with MKL05. This project should be powered with four AA batteries and almentar the useful life of the battery I have to put the PC to sleep (low power) and waking through TSI. Can anyone help me. I got an example of the KL25 that does the same, but when the system calls the function "GotoLowPower ()", the micro sleeps and does not wake up more. It is caught in the "DO WHILE".

Thank you.

Hi Eliezer

The KL05 has an errata about the TSI and the LPTMR, please check it ERRATA 6060 TSI: Out of Range interrupt shows incorrect behavior with some configurations on the following link:

Errata for Mask 2N96F

Because of this is better use the LPTMR to wake up the MCU check if there is any touch and then go to stop again, please check the attached project, this is for the freedom kl05 and use one electrode, if the electrode is not touch for some time the MCU goes to LLS and is waking up periodically to check if there is a touch or not,.

I hope this will help you.

Regards
