CPU_TAP_ID how to read this register
It seems simpe but, it is not. How can I read CPU_TAP_ID register? I can be access only afer connecting debugger but how can it be read?
Resolved! Using STM32H7 Dual Core with Internal Oscillator Only
Hi All,I am interested to use STM32H7 Dual core for my project. To save component and space, May I use it without external oscillator?Thanks
Resolved! STM32L010K8 TIM2_CH4 PWM can't go to PB1
A'm using LL libraty. I need simple PWM output on PB1.TIM2 init related to CH1 and PA5 work.When I change setup to CH4 and PB1 pwm doesn't go to the pin.Both PA and PB ar clocked.Under debuger I checked MODER registers, AF_5 function is selected.Work...
Why the Hyperbus frame sent from NUCLEO-L4R5ZI-P board has not the good shape?
My purpose is to send an "HELLO" using a NUCLEO-L4R5ZI-P board trough HYPERBUS.On the STM32CubeIDE, I configurated OCTOSPI1 peripherial and I/O associated./* USER CODE END Header */ /* Includes -------------------------------------------------------...
stm32f030 programming using stm32 flash loader
hi every one.I want to program an stm32f030 chip using stm32 flash loader. I know this programmer communicates with the boot program of the MCU. I used this programmer for a microcontroller of mine in a custom designed board (which has been programed...
Resolved! weird CANBUS signal shape, different voltages within the same frame?
Question for the Hardware-wise ones:When probing canH and canL with my isulated oscilloscope i get the following signal:different voltage levels inside the same frame??!.Notice how the ACKs are always higher voltage alsoIt doesnt happen always but ev...
consecutive calls to memset causes fault unless I sent compiler optimization for debug
#else static uint8_t l_datastoreStorage[2048]; #endif static uint32_t l_head = 0; static uint32_t l_tail = 0; void hal_datastore_init() { memset(l_datastoreStorage, 0, sizeof(l_datastoreStorage)); memset(l_datastoreStorage, 0, sizeof(l_datastor...
STM32F0 CubeMx SPI HAL Driver Initial Pin Level
Hi there, I created a project with STM32F042G6 chip using CubeMX. I am interfacing this IC to another chip using SPI. When I set the SPI1 and try to send a command, just before sending a command I have SCLK, MOSI, and MISO levels are high. After send...
