STM32 MCUs Products

After reset I see that both PRIMASK and FAULTMASK registers have the value of 0. In my understanding (I could be wrong...) this means that the interrupts are enabled. Is this normal? I would expect the interrupts to be disabled after reset... thanks

When we are sending some data like "hi" in periodic interval of time 100ms STM32f411E discovery getting PC data over uart. But when we send data with fast rate (100ms) then we are facing issue In reception of complete data.

Below api we are using to get data from uart ( HAL_UART_Receive_IT ).

Simulink Coder Support Package for P-NUCLEO-WB55 board and model-based design examples for STM32WB55

Hello,I have the following questions about available support in Simulink:1) Is it planned to add Nucleo-WB55 to the set of supported boards in Simulink Coder (for example to communicate with hardware in Normal Mode Simulation using Connected IO)? If ...

STM32F072xx - How to detect VDDIO2 presence?

DS9826 states that "The VDDIO2 supply is monitored and compared with the internal reference voltage (VREFINT). When the VDDIO2 is below this threshold, all the I/Os supplied from this rail are disabled by hardware. The output of this comparator is co...

Parallel signaling using fsmc

Okay so I'm trying to use FSMC in order to control 16 bitlines and a (custom) clocksignal for driving multiple LED drivers. (the final goal see "data-signal")My first goal was to be able to drive the 16 bitlines, this works as expected. (see "without...

if i use uart dma channel handler for receiving the data by using the uart i received whole but every byte of data got double why

void DMA1_Channel6_IRQHandler(void){ /* USER CODE BEGIN DMA1_Channel6_IRQn 0 */ /* USER CODE END DMA1_Channel6_IRQn 0 */ // HAL_DMA_IRQHandler(&hdma_usart2_rx); /* USER CODE BEGIN DMA1_Channel6_IRQn 1 */ /*Checking the proper USART Port*/  //if (hdma...

stm32lL011 20 led lighting.

I have one stm32lL011 20 pin chip. And nothing more than just this chip, it's a bare chip. How can I turn on a led using a touch button? I don't know what to do, can you write me step by step what to do?Thank you all =)
