app_pwm.h and PWM Examples won't compile

[Dave_couling]

I'm trying to get the PWM example to compile in SDK 10. However I cannot get app_pwm.h to compile. I get the following errors:

1. expected expression before '{' token ble_app_hrs line 70, external location: C:\Nordic_Semi_SDK_10\SDK_v10_Package\components\libraries\pwm\app_pwm.h

This is on the first { in the #define APP_PWM_DEFAULT_CONFIG_2CH(period_in_us, pin0, pin1)

2. Type 'APP_PWM_INSTANCE(PWM1,1)' could not be resolved I'm included app_pwm.h into project include paths as well as in the makefile (along with app_pwm.c). I don't get any other errors on app_pwm function calls except this MACRO.

Thanks guys,

1. I was actually because I could not use a global variable for app_pwm_config_t type.

2. Still no clue??

The second parameter of APP_PWM_INSTANCE() is the timer number. Have you remembered to enable timer 1 by setting TIMER1_ENABLED to 1 in your applications nrf_dfv_config.h?

[Dave_couling]

Yes, this has been enabled.

#define TIMER1_ENABLED 1

Again, I'm simply using the provided PWM example in SDK 10

It was an Eclipse issue, not properly including nrf_drv_timer.h in app_pwm.h.

As a rule, should always ctrl+click on all include files to make sure they are linked to the project properly.
