I'm using two stm32 board, one is stm32wb55-dk which is main board and another is stm32c011 which acts as companion board.I need to establish communication between both using uart to send from main board to companion.connected tx of wb to rx of c0...
Hi,I've been having some troubles configuring DAC channels and can't seem to find what the problem is.I have a C++ class that is intended to setup and control a DAC and I can't write on the registers to do it. My class is the following (dac_test_clas...
Hi I have a STM32L433 processor on a 4 layer board with own ground plane, and below is circuit for VDDA input. I have set the VREF+ to 2.5v, and checked this with my meter, and its perfect (and isnt connected to anything). I placed an accurate 1.026v...
After powering STM32L151V8T6A device, I can't connect to the device. I try to connect by SWD or JTAG without success. Connect under reset doesn’t help. How can I connect the device?
Hi,I had a doubt regarding the timer interrupt stop function.if(isOpen_Unload == 1){ HAL_NVIC_DisableIRQ(EXTI15_10_IRQn); HAL_NVIC_EnableIRQ(EXTI9_5_IRQn); Start_Motor(1); HAL_Delay(5000); HAL_NVIC_EnableIRQ(EXTI15_10_IRQn); HAL_TIM_Base_Start_...
According to the STM32U585 documentation, there is supposed to be a SP1 clock mux selection register, but none is described in the latest programming manual.Does anyone have any idea on what bits I need to set in which register to select the MSIK clo...
NUCLEO-L4R5ZI board, CN12 header: Pin76 = PG7, pin66 = PG8.SB130 and SB131 have been removed from the board. config PG7, PG8 as GPIO output pins, but cannot toggle these two pinsHere is the code: GPIO_InitTypeDef GPIO_InitStructure = {0}; __HAL_RCC...
My PWM and DMA configurations shown in below image and I wrote a simple code to start pwm. As you see below, I set a gpio output pin and after that pwm starting. PWM period has setted to 20ms. What I except, I except start pwm after a few us gpio ...
I'm working with the STM32L476G-EVAL board. I flashed a hello world app onto it, but now I'd like to get back to the beautiful demo app that came with the board. I found the DEMO area of the Sfirmware v1.17.2, but It's a little thin on the instructio...
