LPTIM -- 50ms debounce measuring 62ms ???
I have a scope and am triggering on the falling edge of a pushbutton. The LED drive signal is being monitored on another scope channel. The LED is to turn on 50ms after the falling edge of the pushbutton but in reality it is 62ms. LPTIM1 is runnin...
H725 screen flickering....
I'm using the STM32H725 for development.An image was displayed on the LCD.There is only one screen view, and a container is placed under it, and an image is placed in the container.The image is displayed normally, but the screen is flickering.However...
Resolved! Really poor clock quality on the Nucleo-H753ZI board
I'm trying to use a Nucleo-H753ZI board for an audio (SPDIF) project and, compared with the Nucleo-F746 board I was using, the clock quality is abysmal - off frequency and with loads of phase noise. It appears to be derived from the HSI on the ST-LIN...
Is there a way to force an FUS firmware update even when you have an equal or newer version already installed?
I'm having trouble loading BLE firmware and the failure is always in the last steps of the process. The binary downloads fine and verification passes so I feel like that indicates that it has been successfully transferred to flash. It's only in the l...
Resolved! Not able to access the sdram bank 1 in stm32h757
Hello,I'm trying to access the SDRAM for stm32h757i-eval board and I'm able to successfully store data in the bank 2 i.e, from address 0xD0000000 on wards.But I'm not able to store any data in the bank 1 i.e, at address 0xD0000000.even during assigni...
why does Modbus CRC calculation changes for each cycle, if called in while() loop!
The CRC_Accumulate() function has been called in while loop and the rx_data received as uint8_t and converted into uint32_t and then passed to CRC_accumulate() function in order to calculate the CRC value, but unfortunately the CRC value changes ever...
Enabling Interrupt for UART stops HAL_Delay
Hi everyone,I'm new to the ST world so I apologise if I am asking a simple question.I have a NUCLEO-L4R5ZI-P, I made a new project and cleared the pin outs and started fresh.I have enabled USART2 and can send and receive data in polling mode.If I go ...
How do I maximize baudrate via USART with STM32L4P?
Hi STM32-Community,I'm currently trying to maximize my dataouput. I've about 150 KB/s data, which are sent out via RS485 and connected with a RS485 to USB to my PC. The USART Clock is at 64 MHz, though 80 MHz viable aswell, which means I should be ab...
STM32U5 Cannot enable ADC (timeout on polling for ADC_ISR:ASRDY)
I'm using CubeIDE 1.7.0 and a Nucleo board to initialize and start ADC1 (at default settings, more or less).The issue is that HAL_ADC_Start() would return HAL_ERROR due to a timeout. This is probably Clock-related but I couldn't figure it out yet.Her...
