Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Code formatting applied - please see here for future reference.Hello everyone,I'm currently working on an STM32 project using the NUCLEO-G431KB board. I've come across the BSP_COM API in the STM32Cube firmware, which seems to be an abstraction layer ...
Hello,I would like to understand the code to carry out my software integration : /* Configure SD pin detect */ __SD_DETECT_GPIO_CLK_ENABLE(); __HAL_RCC_PWR_CLK_ENABLE(); And This refers to lines of code that I am lost, for the first line ...
Hello , I am trying to write a USB OTG FS code from scratch (in Device mode) .At this point i can receive and send control transfers .For the Device Descriptor and Set address commands there seem to be no issue but with the Configuration Descriptor t...
Good morning, I'm having trouble understanding how to solve a problem.there is already a software developed in keil 4, but we need to change some things but now we will use keil 5 with the hal library, so far ok without problems.my first problem was ...
Hi, what is the correct way to switch between CAD state machines? For example, between DRP to SNK and vice versa.Motivation: When the battery is bellow the defined SOC, switch from the DRP state machine to the SNK only and stop toggling between SRC a...
FDCAN1_IT0_IRQHandler and FDCAN1_IT1_IRQHandler are not defined in the interrupt table of the file startup_stm32g483xx.s. When an FDCAN1 interrupt occurs, it generates an hardware fault. Adding the FDCAN1 irq handlers to the interrupt table solves th...
Hi,I am curious that how can ı choose electrolytic capacitor of auxiliary circuit? Firstly, I used 10uF electrolytic capacitor at Vcc pin.When I short circuit the output, the HB mosfets has failed.Then I notice that STCMB1 datasheet mention this topi...
This is another issue found in my endeavors to learn Zephyr. When building I get the following error:warning: orphan section `.stm32_sdram2' from `zephyr/drivers/display/libdrivers__display.a(display_stm32_ltdc.c.obj)' being placed in section `.stm32...
Hi, any idea about why stm32xx_hal_uart functions write to USART control registers by ATOMIC_CLEAR_BIT()/ATOMIC_SET_BIT(), while homologous stm32xx_hal_usart functions write to the same registers by CLEAR_BIT()/SET_BIT()?In example:UART_DMATransmitCp...
**Problem:**- When the I2C is enabled, the part can hit the WWDG.- It looks like the pointer to the function `XferISR` is getting set to NULL somehow. - When this happens, the interrupts are not cleared, and it continually fires the interrupt becaus...
