Timer selection for Nucleo F411

Is there an easy way to know what timers are used in the mbed library for wait, timer, timeout and ticker? I need to setup a timer to trigger the ADC independent of the mbed library and I would like to avoid using those timers so I can still use those API calls.

From the code it looks like: TIM5 channel 1 = mbed timeout channel 2 = HAL tick

Can anyone confirm that this is all that's used?

Thanks

For reference: https://github.com/mbedmicro/mbed/blob/master/libraries/mbed/targets/cmsis/TARGET_STM/TARGET_STM32F4/TARGET_NUCLEO_F411RE/hal_tick.c

THis is the hal tick implementation for F411. AS you stated, those 2 are used. Then you got PWM here are pins for your platform https://github.com/mbedmicro/mbed/blob/master/libraries/mbed/targets/hal/TARGET_STM/TARGET_STM32F4/TARGET_NUCLEO_F411RE/PeripheralPins.c#L85. It might be that for your platform all timers are used in these 2 HAL modules.

Thanks I forgot about the PWM pins.
