STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello Everyone,I have a Communication (UARTs) and DMA intense application running on stm32f439z. I am getting a strange Hardfault, not very rarely, I would say one per hour average, related to a wrong address access on the bus. Not happening always...
Hii everyone,I've couple of questions. I'm using Discovery board with STM32F407VG in LQFP100 package. I want to do the boundary scan testing on it. is it possible to do boundary scan testing?is it possible to trace Embedded macro cellis it possible/H...
I set up a basic Master-Slave SPI communication interface from the STM32H750VBT to the STM32F7ZET MCUs in only one direction. And in this workspace I set my hspi2.Init.CLKPolarity configuration as SPI_POLARITY_LOW on both sides. And, as far as I know...
Hi, I am using stm32431. I config LPTIM and call HAL_LPTIM_Counter_Start() but return HAL_TIMEOUT and no pulses is count. When I change HAL_LPTIM_Counter_Start() function putting 'HAL_OK' to be return forced, the pulses is counted normally, but not i...
Hi,I'm using a STM32L432KC on Windows 10. I installed the ST-LINK driver (009) available on ST website and the ST-LINK utility (004).When I connect the STM32 to my computer , it doesn't appear as a STM32 device but as follows in 'other devices' of th...

It also doesn’t erase after starting new debug session. Is that expected behavior? I am using STM32L476, and I downloaded X-CUBE-EEPROM software package, included it into my project and it works fine. EEPROM content is retained after NVIC_SystemReset...
It may be obvious to the rest of the world, but in order to get the ADC to operate in Discontinuous Mode, you must also select Scan Mode. This was Not obvious to me from either the comments in the HAL or the reference manual. The SCAN bit in CR1 appa...
Hello ; I am trying to test usart DMA on F7 . I only can transmite one time ; when i call usart init again its ok . but i still could not understand why . Could you help please while (1) { /* USER CODE END WHILE */ /* USER CODE BE...
I am using STM32L476, running on MSI @ 16MHz, with MR Range 1 and 3.3V supply voltage. The problems described below are happening at room temperature. The processor is running Bare Metal. The ADC1 and ADC2 are configured in Regular Simultaneous Mode ...
