Resolved! Integer types u_int32_t and uint32_t
Hello. Why STM32CubeIDE suggesting me to autocomplete u (unsigned type) as a u_int32_t if it doesn't built? However uint32_t works well. What is the difference using u_intXX_t and uintXX_t?

H5 and FREERTOS
Hi to everybody. I've developed an application using FreeRTOS, under M3 Series.Then moved to M4 without probelms. In CubeMX I can add all the tasks, timers, Mutex and so on.Now I'm porting to H5 MCU, but the freertos disappear from CubeMX. I found th...
Can not read memory! Disable Read out protection and retry
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...
Resolved! ADC input resistance STM32C011J4M6
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 ...
Need some help with STM32L4 RTC
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...
Problems with DMA in Ping Pong buffer schema
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...
Resolved! Which is best STM32 MCU for fast driving of GPIO
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...
Using CYCCNT in STM32G491RE
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...
Resolved! Problem with TIM1 overflow interrupt for STM32G0
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...
