Hi guys,
I am currently working on an library myself, and I like the way st is doing certain things, so I am ''lending'' myself ideas from the HAL.
One thing in particular caught my eye, the callb...

Hi Guys,
I am currently working on a PWM signal of f = 5kHz (T= 200us) with the 32-bit general purposte timer 2. While testing my implementation I am observing a strange behaviour. At the moment I am not sure i...
Posted on January 19, 2016 at 15:59 Hi Guys,
I have some issues with my master-slave time configuration. I simply chain TIM4->TIM1, whereas TIM4 triggers TIM1 every *** ms. As a result TIM1 responds with a single pulse on channel 1.
Th...

Hi Guys,
I am setting up my F427 with a master-slave timer (TIM4->TIM1). TIM4 triggers two capture and compare interrupts, CC2 (CCR2 = 1), and CC4 (CCR4 = 5000). TIM1 is triggered by CC2 signal.

Hi Guys,
I am working on a project, where I need to output a PWM for a certain period of time and then stop and deinitialize the PWM.
In my case, I use timer 1 as my PWM output. I can init...
Posted on June 27, 2016 at 14:05After further investigation of my problem, I found the issue.I was measuring the PWM after an inverter, which is not fast enough. The inverter causes problems below 1us. Measuring at the PIN's of the stm32f4x9 control...
Posted on June 23, 2016 at 14:17Hi Hannibal,It works for duty cycles bigger than 0.5% (~1us). As I said before, I cant wrap my head around the problem at the moment. I will try to make an minimal example for two chips that I have access to F429 and ...
Posted on January 13, 2016 at 15:57I need to take back what I said, I did make an mistake here. Setting the URS-bit is not protecting the f427 to throw an interrupt for CC2 or CC4. In fact it is changing anything for me.On the positive side, if you ...
Posted on January 13, 2016 at 13:29Hi Hannibal & dembek,Thank you for your quick reply. Your fix works like a charm for the problem I stated. Unfortunately, my problem shifted now. The issue is now, after I started the master once, stop the timer, a...
