Hi friends,

First I want to put FRDM-KL05Z board to low power in code warrior. Then by touching the touchpad the board must wake up and I want to control the brightness of an LED using touch pad of FRDM-KL05Z, is there any tutorial for that, if not could you tell me how? Anybody please help...

Hello Yadhukrishnan,

1) About the low power , the attachment "klxx-sc-pex" has a sample created by PE on cw.

Also there is a bareboard sample about low power , this is create on IAR, while the application

code you can refer to , please download it here :

FRDM-KL05Z|Freedom Development Platform|Kinetis MCU|NXP

( KL05-SC\KL05-SC\klxx-sc-baremetal\build\iar\low_power_demo )

2) There is demo about use TSI wakeup kl25 chip , it is the same with KL05.

KL25Z - Wakeup using TSI

3) I find there is a low power mode with TSI , and developed on CW 10.6 about frdm-kl05,

i have not test it , while i check one customer have been used it , maybe you can have a test.

Hello ,

Does your problem been resolved ?

If not , the LED in lowpower mode is the same with normal mode .

Yes, on the CW, we can use PWM component .

Hope it helps
