changing TIM1 Dead-time generator setup continuously
HI,I want to change tim1 Dead-time generator setup continuously between 10 -120first time I set Dead-time with cube mx and it worked correctly sBreakDeadTimeConfig.OffStateRunMode = TIM_OSSR_DISABLE; sBreakDeadTimeConfig.OffStateIDLEMode = TIM_OSS...
Resolved! Timer Interrupt on overflow only
I am capturing an RC PPM signal using an advanced timer with DMA. But now, I want to implement a failsafe in case of a lost connection using only hardware. The closest I got so far is using a separate timer (with pins connected externally) in reset m...

Hi guys,I'm struggling with modem communication on embedded system that does few other tasks in realtime. I'm using TCP stack built in modem (Fibocom G510). This seem to be not complicated, but every time I'm doing it - I'm doing it diffrent way and ...
Trying to understand hdmi/dvi protocol for noobs
The idea of opening this question is to achieve what I put in the title: understand the encoding of the hdmi/dvi signal, in a staggered manner. I don't want to define any microcontroller capable of it yet, but my intention is, if possible (I know i...
RM0440, Rev 7, STM32G474 Reference Manual missing Figure 32
The figure is missing: Also, the figure that was there in Rev. 6 referred to DMAMUX_RGCnCR but it should have been DMAMUX_RGxCR.
About STMF407xx I2S DMA circular buffer playback DMA interrupt inconsistency issue
The STM32F407XX chip is used in the project, and the audio codec chip WM8978 is connected through I2S. The voice data adopts 8000 sampling rate data format 16bit, two-channel. STM32 I2S unidirectionally writes audio PCM data, using cyclic DMA double ...
The values read by my ADC have not sense considering my RES setup (STM32H747).
I am using the VREFBUF as a reference for my ADC reading and I set it up to the max (2.5 V) and used the capacitor circuit described in AN5690 p.2 Fig. 2. The code used for my ADC and VREFBUF are described here : void VREFBUF_Init(void) { SET_BIT(R...
