Clock cycle behavior as a function of frequency
Hello, On the STM32F746ZG I measure the clock cycle needed to execute a code thanks to a timer which runs at the same frequency as the core clock.However, for the same code, with exactly the same measurements process, the clock cycle needed to execut...
How is wrap-around handled in CCR registers
Apologize in advance for what may be a basic question. I have a background in C programming and other languages mostly at the application layer. I have however, supervised, reviewed, and analyzed embedded C code at lower layers from others. My curren...
RM0440, Rev 7, STM32G474 Reference Manual - Errors
Figure 188, Page 853: The last waveform (HRTIM_REPxR = 2) should be: 1, 0, 2, 1, 0 and not 1, 0, 2, 0.Figure 254, Page 933: For the last two waveforms (ADCxPSC[4:0]=4 ADROM[1:0]=01 and ADCxPSC[4:0]=4 ADROM[1:0]=10), it seems like the waveforms as sho...
SPI does not working as expected
Hi,i am working with STM32U575x, I am trying to implement SPI transmission (using the blocking function - HAL_SPI_Transmit.The problem is that sometimes the function is stuck while waiting for EOT event.someone here, in this fourm suggested to redu...
STM32F769 DWT CYCCNT
I'm using the STM32F769-DISC0 development board and am utilizing the DWT->CYCCNT to calculate cpu load as well as using it as a high speed timer that runs at the clock frequency. When the debugger is plugged in, it functions fine. However, with the d...
Generating the pulses for thyristors implemented in 3 phase ac dc control
Hello to everyone! I am an electronic engineer but iam new on stm32.At the moment iam talking only for one phase. i have a square wave of 50Hz => 20ms of period with dutycycle 50% that is implemented in INPUT CAPTURE CH2(PE11) and i have choose the O...
STM32F072R8 ADC EOC is not complete
Hello,I am using ADC1 of STM32F072R8 to measure temperature from sensor. The ADC is being used in continuous mode. For some historical reasons I still use standard peripheral library. Here is my code:void Temperature_ADC_Init() { GPIO_InitTyp...
Resolved! How to execute code from CCM Memory? [GCC, LD, Help]
Hello, i'm trying to execute a delay code from CCM memory but the MCU is frezing when enter to 'delay_ms' function. It is the first time that i try this and i don´t know if the linker file, and the startup file modifications are good implemented so i...
Is it possible to obtain precise Hz increments using a Timer to set BeatsPerMinute?
I need to trigger a timer updateEvent at a rate ranging from 2 BeatsPerMinute to 1000 BeatsPerMinute. I can get the correct range by setting the timer's prescale value from 1 to 30,000 but I need to land on precise BeatsPerMinute integers. If I set t...
