Resolved! X-CUBE-LPUART does not contain any project for STM32U5.
As per application note, it says X-CUBE-LPUART supports STM32U5. I am trying to find example for LPUART Reception in LPBAM but I am not able to find any example. Cube IDE has one example but LPBAM mode configured only for transmission. For the recept...
Resolved! How to read wall clock time on NUCLEO-L476RG
Hi,I'm trying to set the RTC date and time when uploading my code to a NUCLEO-L476RG board. I've already configured the RTC in CubeMX, and it works as it should. But I've only managed to set the time manually by setting the BCD values for Hours, Min...
Resolved! What voltage should be clamped on for analog input, vref or VDDA? At what condition positive injected current happen when the pin is used as analog input?
Hi, I'm using STM32H7A3, and I’m a bit confused about injected current for pins used as analog input. In our design, I used both 5V tolerant and 3V tolerant pins as analog input. And VDD=3.3V, VDDA is connected to VDD with a bead. And Vref is 3V. And...
Is it possible to erase Full chip?
Hello, I have a question:Is it possible to erase full chip (for example... erase full chip after counter value get value 100)?I'm using stm32f303cb.Thank you for your time,Domen
Adding user code to STM32G0B1KC main.c boots to a random address with Error: failed to download Segment[0]
Not quite sure how to best document this problem. But I am porting a current project of mine from an STM32G4 to STM32G0. All of the peripherals are configured correctly and the code base is mature and running well.When I debug the project with no use...
ADC gives clumped values that result in a poor waveform.
hadc4.Instance = ADC4; hadc4.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV4; hadc4.Init.Resolution = ADC_RESOLUTION_12B; hadc4.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc4.Init.GainCompensation = 0; hadc4.Init.ScanConvMode = ADC_SCAN_DISABLE; ...
MEM TO MEM DMA
I am using STM32H743ZI2. I am using 6 ADC with external timer and dma to acquire data. After I acquire adc data (16bits), I will use scale ratio to obtain physicals value I would like to get. This value will be 32bits. After I do power (a x a), the r...
GPIO after reset value
Hi everyone,First of all thanks for your answers and sorry for my english level.I checked the reference manual of my MCU (RM0468) and I realized that the after reset value of the most GPIO is high impedance.I need to stablish a new after reset value ...
STM32L071 - Is explicit HSE disabling needed before entry to the Stop mode while system clock running from HSE?
In the STM32L071 reference manual, there is following statement regarding STOP mode entry with HSE as a system clock:"If the application needs to disable the external clock before entering Stop mode, the HSEON bit must be first disabled and the syste...
