[close]file can't connect when adding pwm to ble uart example

[Ben]

Hello everyone, I encounter a question. I follow below link to solve the issue.

https://devzone.nordicsemi.com/question/104118/adding-pwm-to-ble_template/

I've set the TIMER_ENABLE, TIMER0_ENABLE, TIMER1_ENABLE and APP_PWM_ENABLED from 0 to 1. And, I've added nrf_drv_ppi.c to file. But, IDE still show Error: L6218E: Undefined symbol nrf_drv_ppi_channel_assign (referred from app_pwm.o). Error: L6218E: Undefined symbol nrf_drv_ppi_channel_disable (referred from app_pwm.o). Error: L6218E: Undefined symbol nrf_drv_ppi_channel_enable (referred from app_pwm.o). Error: L6218E: Undefined symbol nrf_drv_ppi_channel_free (referred from app_pwm.o). Error: L6218E: Undefined symbol nrf_drv_ppi_init (referred from app_pwm.o).

I use the "Go to definition" to find it in app_pwm.c It can't be found. It displays source browser 'nrf_drv_ppi_channel_assign' - undefined Definition/Reference.

Please help me to solve this issue. Thank you.

Hi,

Looks like you need to have #define PPI_ENABLED 1 in sdk_config.h. Remember that you can edit sdk_config using the configuration wizard.

Thank you, I've solved it. It really happened in that I don't enable PPI_ENABLED.
