Hi, For a reason that I cannot explain, the STM32U575ZI (on the nucleo board) is sending a CAN bus message with infinite repeats and 100% bus utilisation, but I have repeated transmission turned off (DAR bit set to 1) and I have confirmed this using ...
Hello everyone,I am developing a custom PCB and am having a problem while trying to flash the chip.Before delving further, I need to say that I have made a mistake with routing the JTAG traces to 10pin JTAG connector and may have burnt the chip. I tr...
Hello,The setup comprises a keyboard connected to the Host-configured USB port of an STM32F4 dev board and the keyboard is configured with the following two HID Report Descriptors: 0x05, 0x01, // Usage Page (Generic Desktop Ctrls) 0x09, 0x06, ...
I'm searching for super coding comfort in CubeIDE. Currently TIM2 resets/updates.In HAL_TIM_PeriodElapsedCallback() I "manually" start HAL_ADC_Start_DMA() the Scan conversion of four channels and have the four results shipped into my progs memory,...
Given: void USART2_Init (void) { RCC->APB1ENR |= (1<<17); RCC->AHB1ENR |= (1<<0); GPIOA-> AFR[0] = (7<<8); GPIOA->MODER |= (1<<5); USART2->BRR = 0x0683; // 9600 at 16MHz USART2->CR1 |= (1<<3); USART2->CR1 |= (1<<13); } void USART2_Write(...
Hi,I'm using the internal bootloader of the STM32L522 with STM32Cube Programmer to upload code via UART. I can upload new code without any issues. The problem is that I need the application to start after the programming is complete. I have the "Run ...
Hi there,this is my first post here and also the first time that I mess around with STM32 processors.A few months ago I decided to start a new project for realtime audio processing with DSPand the STM32H7 series seemed to me a good candidate for what...
Hi All,We are currently working with the STM32U083RCT6 microcontroller for a capacitive touch switch and LED drive design. While all other functions are working correctly, we are encountering issues with the touch sensing functionality on pins PB5, P...
Hi for everyone,I try to implement window watchdog to my system. I got reset every single time during enabling watchdog in HAL_WWDG_Init() function and exactly WRITE_REG(hwwdg->Instance->CR, (WWDG_CR_WDGA | hwwdg->Init.Counter)); here. These are my w...
Hello,I am having trouble configuring and enabling DAC on my U575CGTx. I am a beginner programmer, and I have very little experience programming STM32 MCUs. Reading through the reference manual feels like learning Chinese.I do not have an external os...
