FWLib V1.0 to V2.0 migration steps

same but the name is different. In the function name, “TIM1” was changed to “TIM” and a

new parameter was added to specify the timer to be configured.

e.g.: in FWLib V1.0 the function used to configure the TIM1 interrupt is:

in FWLib V2.0 the function is:

Some typical examples of the TIM1 configuration migration from FWLib V1.0 to V2.0 are

given below. For the complete list of changes made in the timer driver, please refer to

Appendix A.

Time-base configuration

Typical code for TIM1 time-base configuration based on FWLib V1.0:

TIM1_TimeBaseStructure.TIM1_Prescaler = 0;

TIM1_TimeBaseStructure.TIM1_CounterMode = TIM1_CounterMode_Up;

TIM1_TimeBaseStructure.TIM1_Period = 4095;

TIM1_TimeBaseStructure.TIM1_ClockDivision = 0;

TIM1_TimeBaseStructure.TIM1_RepetitionCounter = 0;

Using FWLib V2.0, the function name has to be updated and TIM1 should be passed as the

first parameter value:

TIM_TimeBaseStructure.TIM_Prescaler = 0;

TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;

TIM_TimeBaseStructure.TIM_Period = 4095;

TIM_TimeBaseStructure.TIM_ClockDivision = 0;

TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;

TIM1 output compare mode configuration

Typical code for TIM1 output compare mode configuration based on FWLib V1.0:

TIM1_OCInitStructure.TIM1_OCMode = TIM1_OCMode_Timing;

TIM1_OCInitStructure.TIM1_OutputState = TIM1_OutputState_Enable;

TIM1_OCInitStructure.TIM1_OutputNState = TIM1_OutputNState_Enable;

TIM1_OCInitStructure.TIM1_Pulse = 2047;

TIM1_OCInitStructure.TIM1_OCPolarity = TIM1_OCPolarity_High;

TIM1_OCInitStructure.TIM1_OCNPolarity = TIM1_OCNPolarity_High;

TIM1_OCInitStructure.TIM1_OCIdleState = TIM1_OCIdleState_Set;

TIM1_OCInitStructure.TIM1_OCNIdleState = TIM1_OCIdleState_Set;

TIM1_OCInitStructure.TIM1_Pulse = 1023;

TIM1_OCInitStructure.TIM1_Pulse = 511;

Using FWLib V2.0, the function names have to be updated and TIM1 should be passed as

the first parameter value:

TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Timing;

TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;

TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Enable;

TIM_OCInitStructure.TIM_Pulse = 2047;

TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;

TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_High;

TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;

TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Set;

TIM_OCInitStructure.TIM_Pulse = 1023;
