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...
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...
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...
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...
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...
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...
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 ...
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...
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...
Hello STM Community! This is my first Question in this Forum.I am using a STM32L081KZT and I need to save data, when the Power is unplugged. My setup is powered by USART and can only be turned off by unplugging the UART cable. In that case I need to ...
