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...
Is it somehow possible to turn on ETM trace while STM32F4xx is running in bootROM? So far I wasn't much successful. I don't know if it's due timing (correct frequency) or that MCU uses internal HSI oscillator by default.ETM in "normal" programs is no...
