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...

I need to fill certain RAM (buffer) locations with known values (i.e. compressed audio) during a CubeIDE debug session. I thought there was a way to load values into RAM while the program was stopped at a breakpoint. But I can't seem to find this too...
