SPI Miso pin

hello , ı use stm32h750vb I m trying work spı,I'm trying to raise the miso pin at the beginning of the dialog, I'm wondering how you can do it.

Resolved! STM32L072 - PWM out of PB15

I am using the STM32L072CBT and wish to use PB15 as PWM output. I have created the project in CubeMx but selecting PB15 offers no timer channels at all. I have double checked the data sheet which shows PB15 with AF1 as TIM15_CH2. I have created a new...

Software doesn't work when switching to a other revision of board

I'm using a STM32F469 Discovery board, i was using a board with B-01 revision, my software works just fine, now i want to use the same board but with B-03 revision but for some reason the same software doesn't work on this board.Note: B-01 rev flashe...

DMA1_Channel1_IRQHandler() is not getting triggered

Hello, I am using STM32G030F6Px, it has 32 KB flash memory and I need free space to save data in flash, also it needs to have bootloader. That's why I decided to use bare metal code instead of HAL library, of course I did this by examining HAL librar...

Ensuring that goto from one function to another function always works properly?

I am working with the STM32F446 microcontroller and compiling with Eclipse/GCC. Short version: I have two functions, main1(int argc, char* argv[]) and main2(int argc, char* argv[]) and I want to be able to goto back and forth between the two many tim...

udp_recv trigger when input data available.

Hello,I'm using stm32h757i-eval board & STM23cube ide for programming.I have successfully achieved the UDP communication.But there is one problem.I want a trigger or auto polling function for the UDP_RECV i.e, when ever there is a input data availab...

Resolved! __weak requirement on stm32f4xx_hal_pcd.h functions

I have default setup under linux with CubeIDE 1.7.0 and for overriding, i had to modify as __weak void HAL_PCD_ConnectCallback(PCD_HandleTypeDef *hpcd);__weak void HAL_PCD_DisconnectCallback(PCD_HandleTypeDef *hpcd);oh header definitions. Otherwise i...

Is the formula for the frequency of the sine wave generated by the D / A converter in the document from ST incorrect?

Hi,I generate a sine wave on the DAC. To trigger the DAC, I use the TIM 2 timer, which is clocked on the APB1 (32 MHz) bus, then I reduce its frequency through the dividers PSC = 15 and ARR = 1. In this way, I obtain the frequency from the timer equa...

HAL_GPIO_EXTI_Rising_Callback or EXTI0_1_IRQHandler

Hi, is there a reason to implement the HAL function over simply running code inside the IRQ handler.In my current case I only am incrementing a counter and do not need to demux the line, so I presume not this time, but if I was doing something more i...
