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...
HiMaking a very simple freeRTOS project with only one timer on a bluepillthe LED is blinking with 1000 hz = tick rate and not with 1 hz as programmed ...What did i do wrong ? /* Create the timer(s) */ /* definition and creation of myTimer01 */ osTime...
Suppose I have the following code snippet:void some_func() { int data = GPIOA->IDR; if (data == 0x01) func1(); else if (data == 0x02) func2(); }If optimization is turned on, I would expect the compiler to remove variable data and replac...
I noted that when I call HAL_GPIO_DeInit is called (stm32h7xx_hal_gpio.c v1.4.0) the wrong External Interrupt get's de-initialized. After investigating further and comparing to the previous version I noted the following in the external interrupt de-i...
Hi dear community members,I am trying to communicate with my computer using STM32F407 and Qt creature or matlab, data sending or receiving but I think my information still is not right place.First I tryed to send ping for computer.I connected the ST...
Hello,I downloaded an example for IoT and the Cube library from this address. The program works well in the first step, but the problem starts when problems occur due to a weak wifi signals or a lack of Internet stability, and the board should be res...
Hi,is there a way to program a STM32 Nucleo board (Nucleo-F767ZI) via the Ethernet interface?The problem with the usb port is when the Nucleo 5V is powered externally via the E5V pin, at power on of the 5V, the usb cable must be removed. So on a remo...
Hello there,I am considering a basic TCP/IP application with ethernet connection. At first I lookned at the STM32F107 and STM32F750 series MCU's, as they have the ETH peripheral. But then I looked how much they cost, and after that how much do PHY's ...
Hi All,I am currently occasionally receiving corrupted data on my UART2 (STM32F302). By corrupted data I mean receiving a character which I am not expecting.I am running a 32MHz UART2 Clock and using a baud rate of 9600 with oversampling at 16. So Th...
