Hey Guys,I have problems about configure my STM32H743VIT SysClock.On my own PCB, i have a Crystal with 8 MHZ, and a LSE of 32.768 khz.Settings are in my Screenshots, now if i debug my application, it ends in a Error Handler.. but why?BTW: UART4,5,7 a...

Hello!I have a new project with a STM32F407VET6 and a STM32F103xxx over a RJ45 Jack with I2C.i worked a lot of time with I2C EEPROMs and it works fine, but my communication between the 2 STM's are horrible, or i am too confused.i found the tutorial o...

Hello,I am not really new, but i have a courious problem.I have a STM32F103CBU6 device (new), and started a new C++ Project with STM32CubeIDE 1.13.2 and the STM32Cube FW_F1 V1.8.5 firmware package.I have a external crystal for both (HSE + LSE) and is...

Hey,I enabled only the HSE and LSE and changed my system clock to 160 MHZ in CubeMX.After i disabled my wrong soldered HSE, the system clock is changed to 75mhz after i clicked "resolve clock issues"CubeMX sets automatically the VOS2, i changed the V...

1. No, i can solder it tomorrow.2. my ioc in attached.Okay, it's the forgotten CL load capacitor, i tested my config with disabled HSE and enabled LSE, and it worked.*** it... this errors costs a little bit of time... thank you for help me!

Hello,my configuration with crystal (no XO) 8 MHZ is this:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Supply configuration update enable */ HAL_PWREx_ConfigSup...

Hello,Sorry for my confusion, the day is long...i have only a crystal on my pcb with 2 pins (not a crystal oscillator, with 3.3V supply), the crystal swings with 7.99997 MHZ on my oscilloscope. i check my schematic, and i found a big problem, i have...

Hello, Sorry, I have a XO with 8 MHZ and 2 Pins, the Code jumps to the Error_Handler while Waiting for HSE has been ready. I checked with my osci, and i get a 8 MHZ signal from the XO. /* Wait till HSE is ready */ while (__HAL_RCC_GET...
