PWM

[harrys]

Hi,

i am working on nrf52dk. i want to include "pwm" example in "ble_app_uart" example . i have included all the header files. and functions in "ble_app_uart" example.

the error shown is  " 'NRFX_TIMER2_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_TIMER_INSTANCE'? "

Hi,

Have you enabled the PWM instance in the SDK config file and included the paths to the pwm source files in the project settings?

regards

 i have added 

"

#include "app_error.h"
#include "bsp.h"
#include "nrf_delay.h"
#include "app_pwm.h"

APP_PWM_INSTANCE(PWM1,1); // Create the instance "PWM1" using TIMER1.

static volatile bool ready_flag; // A flag indicating PWM status.

void pwm_ready_callback(uint32_t pwm_id) // PWM callback function
{
ready_flag = true;
}

"

and in sdkconfig.h configured pwm as 

#ifndef APP_PWM_ENABLED
#define APP_PWM_ENABLED 1
#endif

i have not included  any paths to pwm source files in project settings.

can you tell me which path i have to include to run pwm in "ble_app_uart"

Hi,

Just to be sure, do you want to include the app_pwm that uses the PWM library, or the PWM driver that uses the PWM peripheral?

yes i want to include app_pwm

Hi,

I've attached an example that merge the pwm library example with the ble_app_uart example. 

best regards

YES, your code is working.   i did similar changes but i am facing a issue with compilingble_app_uart_PWM_1.rar

[harrys]

can you tell me how i can disable pwm. i want to do off the led connected on pwm. i could not access that pin as gpio once it is initialized as pwm.
