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...
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...
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...
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...
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...
I want to implement the oversampling feature in the ADC read to get a better resolution for my values. Data is transmitted directly using DMA.If I enable oversampling, I can correctly get an average value when putting a 16x oversampling ratio (the ma...
Posted on January 22, 2018 at 20:31Hello everybody!I want to make a simple VoIP client handling SIP and RTP protocols. It needs to be very simple (connect to the VoIP server, make a call, pick up a call, end call), fast and reliable. I'm wondering ...
Dear experts,Still not sure after reading the fine manuals. On CM7 (STM32H7, F7) if I and D caches have never been enabled after reset, can speculative data fetch and instruction fetch still occur?Is speculative access independent from caching?
Hi all,I am using a custom board designed using mcu STM32 L071CZ. I want my device to go to stopmode afte doing a certain task. I checked the current consumption in run mode, it is almost 4.7mA and in stop mode in 3.56 mA.I haven't enabled any othe...
