kinetis FRDM-K22F tpm

[kentgu]

hi,

Now I want to realize PWM output using FRDM-K22F tpm to with IAR. In "c:\Freescale\KSDK_1.3.0\Examples\frdmk22f\driver_example" folder, there is no tpm demo project. I copy the project"c:\Freescale\KSDK_1.3.0\Examples\frdmk22f\driver_example\gpio", and move the content of main.c from "c:\Freescale\KSDK_1.3.0\Examples\frdmkl02z\driver_example\tpm".

I just copy

"

volatile uinit32_t cnt = 0;

int32_t setp = 1;

tpm_general_config_t driverInfo;

"

report the error "Error[Pe020]:identifier "tpm_general_config_t" is undefined.

I try several solution, still can't solve it.

#1,Include "fsl_tpm_driver.h" in the top side of main.c because :tpm_general_config_t" is defined in the "fsl_tpm_driver.h", can't work.

#2, In"ksdk_platform_lib" increase "tpm" folder, the folder include "fsl_tpm_common.c", "fsl_tpm_driver.c",fsl_tpm_driver.h", fsl_tpm_hal.c", "fsl_tpm_hal.h". And make new "libksdk_platform.a", can't work.    

Any reply is appreciated.

thanks!

Hi kent gu,

      Actually, KSDK1.3.0 have the PWM code, it is not TPM, just FTM, K22F have FTM module, not named as TPM, FTM is the enhanced TPM module.

    Please run the code in path: C:\Freescale\KSDK_1.3.0\examples\frdmk22f\driver_examples\ftm

    This is the code which you need.

Wish it helps you!

Have a great day,

Jingjing
