I will be using STM32F4 CPU in custom boards. The PCB will be space constrained and I plan on using STMX&IDE for development debug/programming devices. So is there a need for JTAG interface (10 pin) or can I get away with just having the SWD header?
I'm working on PCB with two MCUs, and I'm not sure how to connect power supply lines. Even after reading the datasheet and RM0433, I still find it confusing. Like, which one of the VDD33USB or VDD50USB should I connect and why? Do I connect both? Or ...
I would like to be able to detect when the virtual com port gets opened by some program and when it closes the port.How would I do that?
Hi,I am using stm32L431 and trying to use LPTIM to count pulses.When I call HAL_LPTIM_Counter_Start() return HAL_TIMEOUT in if (LPTIM_WaitForFlag(hlptim, LPTIM_FLAG_ARROK) == HAL_TIMEOUT) { return HAL_TIMEOUT; }But if I comment this part of function...
The problem that I am facing is that I implemented HAL_UART_Receive_IT function in a while(1) loop and then I check for the elements of buffer for \n or \r. After I type the first message it prints "String Received". But after that it continuously ...
The processor never wakes up from STOP1 mode and I do not know why.Reading RTC time and date works, so I know the RTC clock is running. With debugger (using HAL_EnableDBGStopmode()), I notice that the firmware is stuck in __WFI()I'm using STM32Cube_F...
Hi, we're trying to port an application from a F7 chip to the STM32H7 mostly for the purpotedly better performance of the ADC on the H7. However, we've run into an issue I'm not sure I can explain. I'm using the H747 Disocvery board as a prototype at...
Hi. I have two sensors connected to an STM32f410r8t6, where they send a high signal whenever new data is ready to be read. Pin connections are as follows: PC9 (GPIO_EXTI9) -> INT_IMU2PC7 (GPIO_EXTI7) -> INT_IMU1I have them setup as follows in the ioc...
