Hello,I would like some advice on understanding a code with an example provided with the STM32L5xx evaluation board. I have this code below : /* Initialize the data buffer */ for(int i=0; i < PLAY_BUFF_SIZE; i+=2) { PlayBuff[i]=*((__IO uint1...
Hi,I’m working with an STM32H743 and trying to use the RTC. Everything works fine using the LSI, but when I try to use the LSE (with an external oscillator permanently connected to VBAT to keep track of time even when the system is powered off), I ca...
I'm using an STM32H733 running from HSE clock with CSS disabled.In a normal situation, the used GPIO inputs correctly read as HIGH as they are pulled HIGH by an external pull-up / LVTTL (push-pull) drive, verified with the oscilloscope.After exposure...
I'm using a Nucleo-U575ZI-Q board to test Azure USBx MSC storage protocol strack against an Ubuntu-16.04 LTS host, using STM sample MSC code stripped down with a dummy interface against local storage.A Beagle USB 5000v2 is connected between host and ...
I am experiencing an issue with SPI communication on the STM32F746BG microcontroller:Current Setup:SPI2 connected to ADCSPI6 connected to EthernetCurrent Behavior:When testing SPI2 (ADC) alone: Works properlyWhen testing SPI6 (Ethernet) alone: Works ...
Both STM32H730 datasheet and application note AN5050 mentions that a write operation can be performed on external Flash memories through the OctoSPI peripheral.However, the STM32H730 reference manual (RM0468), has the following info on section "25.4....
I am using a NUCLEO-F767ZI Board.Previously I have not used or configured any GPIO. Then I used CubeMX to reconfigure 3 Pins to Inputs with Pull-Down like this: if (HAL_GPIO_ReadPin(button_uncouple_GPIO_Port, button_uncouple_Pin) == GPIO_PIN_SET) {I...
HelloI have found a bug that stops updating the RTC_TR register. There is no problem with the RTC clock itself, it is ticking but the content of RTC_TR might in some specific use cases stop updating.I use the latest STM32CubeH5 Firmware Package v1.5....
Hi, we are developing a USB PD sink device which will operate up to 28V @ 5A.The STM32G431 seems to be ideal for our application, however it seems that there is no official support for EPR within the TCPP software yet and I am unable to set a PDO hig...
Hi there,ContextI implement a basic code where I check the reset cause flag SFTRSTF (i.e. software reset). If this flag is active, I activate the LED on (LED off otherwise).I read out the reset cause from:uint32_t myResetCause = RCC->CSR; RCC->CSR |=...
