- The STM32F10x TIM1 peripheral offers the possibility to program in advance the
- configuration for the next TIM1 outputs behaviour (step) and change the configuration
- of all the channels at the same time. This operation is possible when the COM
- (commutation) event is used.
- The COM event can be generated by software by setting the COM bit in the TIM1_EGR
- register or by hardware (on TRC rising edge).
- In this example, a software COM event is generated each 100 ms: using the Systick
- interrupt.
- The TIM1 is configured in Timing Mode, each time a COM event occurs,
- a new TIM1 configuration will be set in advance.
- The following Table describes the TIM1 Channels states:
- -----------------------------------------------
- | Step1 | Step2 | Step3 | Step4 | Step5 | Step6 |
- ----------------------------------------------------------
- |Channel1 | 1 | 0 | 0 | 0 | 0 | 1 |
- ----------------------------------------------------------
- |Channel1N | 0 | 0 | 1 | 1 | 0 | 0 |
- ----------------------------------------------------------
