Hi @James123,

You can find the Emios_Icu_Ip_BlinkLed_S32K344 example under the following installation path for the RTD:

C:\nxp\SW32K3_S32M27x_RTD_R21-11_4.0.0\eclipse\plugins\Icu_TS_T40D34M40I0R0\examples\S32DS\S32K3XX

With the following examples as well:

This example controls with input in ICU-eMios pin through IcuSignalNotification function, a GPIO trigger will generate edges to ICU input pins. The interrupts will be generated for the ICU channels and the user's functions will be called; the user's functions will blink LED.

Hope you find this helpful!

Best regards,
Julián.

Hi @James123

This example is found under the RTD installation path. If you have the latest RTD installed, you can import the example instead from Design Studio:

As for the functions, you can try to implement Emios_Icu_Ip_GetDutyCycleValues, this function reads the coherent active time and period time for the given ICU Channel.

Hope you find this helpful.

Best regards,
Julián

Hi @James123,

Are you utilizing the example from the RTD, or are you implementing the configuration in a new project? If you are using the example, please take into consideration which channel was initialized:

Also, the function states the following: Emios_Icu_Ip_Init must be called before. The given channel must be configured in Measurement Mode Signal Measurement, Duty Cycle Values.

Best regards,
Julián.

Hi @Julián_AragónM

This SAIC example code is not working. The Red LED of the S32K3X4EVB-T172 evaluation board is not blinking according to the given program. Can you send me the working version of this example code for the board I'm using?

Hi @Julián_AragónM
One more thing. Please send this example code for RTD v4 version of the design studio?

Hi @abdul_rahman,

Have you connected the GPIO trigger and channel 1 for EMIOS?

Best regards,
Julián

Hi @Julián_AragónM

Must've slipped my eye about connecting the pins. The code is working fine now. Thanks for the help.
