In STM32G474.svd version 2.1 that can be download from STM32G474RE product page , WWDG peripheral has no interrupt defined but it is actually the first (0th) interrupt. Is this a mistake or there is a reason behind not defining it in the SVD ?
Hello,recently I'm working on a project based on STM32F103 MCU and an I2S codec chip. The codec has two data port, one is DAC IN and the other one is ADC OUT. What I wanna do is using the codec to play audio or to record audio.According to my knowled...
Hello. I have an STM32F407 development board. While I was getting used to this card last week, the card put itself into memory read protection. When I try to debug or throw code, the attached warning appears and the attached Fail file is created. Eve...
Hi everyone,I am using the STM32C011J4M6 in the SO8N package.I want to use the ADC on a low frequency signal (around 1kHz). My application needs to be very low power so I decided to put a big (around 100kOhms) input resistance on the ADC pin like we ...
I have a very simple example of using the RTC. My trouble is I never get an interrupt when the alarm time comes. Clearly there is something very basic I am not getting quite right. Many, if not all of the examples mentioned in this forum and includ...
Hello everyone i am quite stuck and i want to se if you have any idea.I am making a project wich has 3 devices. - ESP32 wich receive from bluetooth an audio stream- Nucleo F401Re wich receive from the ESP32 via I2S the audio and then process it.- MAX...
I need fastest MCU that can drive GPIO pins but not with timers or DMA, just from source. I need to take fast data from a FPGA device. One of determination is max frequency of toggling pin:I try STM32H562 to toggle pin mode max frequency is around 31...
Hi every oneI want to use DWT->CYCCNT in my software for STM32G491RE. I used these 2 lines to enable it:CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk; DWT->CTRL |= DWT_CTRL_CYCCNTENA_Msk; But when I see with the debugger it seems that it does not wr...
Hello,I'm studing timer, and I wanna raise an interrupt every second using the Timer1.I write this code in main:rcc->APBENR2 |= RCC_APBENR2_TIM1EN_Msk; //Enable Timer1 clocktimer->CNT = 0;timer->ARR = 1000;// up to 1000timer->PSC |= 16000 - 1;//actua...
