Posted on November 07, 2017 at 20:11The following is a code snippet from theSTMCubeF2\Projects\STM32F207ZG-Nucleo\Examples\TIM\TIM_DMA\Src\main.c file: TimHandle.Instance = TIMx; TimHandle.Init.Period = uwTimerPeriod; T...

Posted on November 03, 2017 at 03:59I am trying to use the HAL timer PWM DMA to implement something similar the TIM_DMABurst example in the STM32xG_EVAL directory but for more than 1 waveform.The TIM_DMA example in the STM32CubeMx STM32xG_EVAL direc...

Posted on October 10, 2017 at 21:17The 'STMCubeF2\Projects\STM32F207ZG-Nucleo\Examples\TIM\TIM_PWMInput' example configures the timers with direct calls to the HAL.I am trying to keep all of the pin allocation and resource initialization within STM3...

Posted on November 09, 2017 at 18:08The problem is that the repeat counter functionality is required for this example to work. In other words this example will not work, as written, for this processor.It just serves as an example of how frustrating...

Posted on October 21, 2017 at 01:43I just wanted to say thank you. I got this working using one of the 32 bit timers running at 60MHz.The only thing that is surprising is the inaccuracy of about +/- 100Hz at 38KHz and about +/-3% on the duty cycle....

Posted on October 14, 2017 at 17:47Thank you very much for the help.What should the setup for the timers be in STM32CubMX?

Posted on October 13, 2017 at 00:25Thank you for your help.Do I need to enable the input capture interrupt or the global interrupt for the timer?Do you have a code sample I might look over or can you point me towards some documentation?Thanks again.

STM32F207G-Nucleo TIM_DMA example sets the repeat count for a timer that doesn't have a repetition counter???

How to use the HAL TIM_PWM_Start_DMA() for PWM generation updating Frequency, Duty Cycle and Repetition Count

Has anybody converted the PWM frequency and duty cycle measurement exmaple from the STM32CubeMx examples to use STM32CubeMx to configure the hardware (.ioc file to configure the timers)?
