confict of timer2 when using PWM on nrfread_desktop_2(nrf51822)

[andy]

Hi, nordic staff:

I'm developing a project on nrfready_desktop_2_v3.1.0, as the chip is nRF51822; I need 3 PWM channels for RGB leds. and i found there is a file named app_pwm.c; But there was a building error, list at follow:

Error: L6200E: Symbol TIMER2_IRQHandler multiply defined (by nrf_flywheel.o and nrf_drv_timer.o).

I didn't found the file nrf_flywheel.

could you help me to solve the issue?

Thanks!

Hi,

TIMER2 is used by the Gazell library, as described here. If you do not use BLE/softdevice, you can change the included library to gzll_sd_resources_arm.lib, to use TIMER0 instead. It you use both Gazell and BLE, you can use TIMER1 for the PWM instance:

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

Best regards,

Jørgen
