Timer Example Issue

[phipi]

I'm building a new application based on the no softdevice template example. I pulled in the code from the UART BLE example to redirect printf to the serial interface and that works. Next I wanted to add a timer so I copied the timer example but the timing off the interrupt was completely off.

At long last I discovered that the template example has Timer 0, 1, 2 all enabled while the Timer example only has timer 0 enabled. By disabling timer 1 and 2 my application started working. Can someone explain why disabling those two timers caused the application to start working again?

Are you using SDK 14? I will take a closer look at this case tomorrow.

I'm using SDK12.3 on the nrf51822 with no softdevice

Very sorry for the late response. I've taken a look at this case over the last few days, but have not found a definite solution yet. Just to get things clear, are you using the no softdevice template example located under examples/peripheral/template_project folder in SDK 12.3? For the UART BLE example, you're referring to the example under /ble_peripheral/ble_app_uart/ folder, right? And lastly, the timer example is located under examples/peripheral/timer, right? Sorry for this stupid question, it's just I don't want to spend a lot of time looking at code and then realizing after a while that I am looking at different examples compared to you. I will get to the bottom of this soon.

I'm looking at the template example right now (i.e. the one mentioned in my previous comment), but it seems like only Timer 0 is initialized there in the main.c file.

const nrf_drv_timer_t MYTIMER = NRF_DRV_TIMER_INSTANCE(0);

It seems like we are looking at different examples. Could you specify where you found the template example you are referring to? Cheers, Bjørn

Thanks for the response. Yes that is the template I'm referring to. The way I had to disable the timer was by opening sdk_config.h and entering the Configuration Wizard view. Then under nRF Drivers > TIMER_ENABLED we see TIMER0_ENABLED, TIMER1_ENABLED and TIMER2_ENABLED are all selected. I had to unselect timer 1 and 2 in order for my application to start working
