I need a support to understand how I can configure the TIM Peripheral of my stm32l1xx (TIM8 for example) to develop a time base unit. I have to configure it for generating an interrupt every 100usec.
In the Structure if the Library there are same field that I don't understand how this are related to the clock frequency and output timer frequency. This field are:
TIM_TimeBaseStructure.TIM_Period, TIM_TimeBaseStructure.TIM_Prescaler, TIM_TimeBaseStructure.TIM_ClockDivision .
Can sameone help me to understand this fields and to understand how to configure the TIM Peripheral?
