I want touse TIMER3 and TIMER4 in nRF52832

[Andres]

I am using a development board PCA10040 with an nRF52832

I am running one of the examples: gpiote_pca10040

Everything is working fine with this line in the original example:

static nrf_drv_timer_t timer = NRF_DRV_TIMER_INSTANCE(0);

However, I want to use TIMER3 and TIMER4, so when I type: static nrf_drv_timer_t timer = NRF_DRV_TIMER_INSTANCE(3);

I get this error (Using IAR for ARM):

Error[Pe020]: identifier "TIMER3_INSTANCE_INDEX" is undefined C:\nRF5_SDK_v11.0.0-2.alpha\examples\peripheral\gpiote_Test_AA\main.c 41

Would you please tell me what I am missing (I am new with the nRF52)?

Thank you!

Go to the file nrf_drv_config.h and change lines

#define TIMER3_ENABLED 0
#define TIMER4_ENABLED 0

to

#define TIMER3_ENABLED 1
#define TIMER4_ENABLED 1

This information should be in the documentation of the SDK, this took many hours. Thank you anyway
