Hi, I am unable to interface with a sensor over RS485. I have a uart->RS485 converter hooked up to pins for USART1 (Tx on PD8, Rx on PD9) on a Nucleo-F439ZI.I also have a USBtoRS485 converter with which i'm able to communicate to the sensor fine. I h...
Hi! I wonder if it is possible to set up the STM32H7B3 µC as a synchronous usart slave with the usart1 peripheral. From the reference manual it seems that it is only possible to set it up in 'SPI-mode'. The functionality I want is a USART slave that ...
Hi all,I want to increment the lap_marker variable only once when the lap_button is pressed, but when I press the button, it increments multiple times, untill I let go of the button (when I put a breakpoint in the loop it works fine).I only want to i...
Hello,I have been trying to make a driver for the Winbond W25Q512JV, It's works normally ( I can read/write data, erase sector/chip, can write image as external flash loader with Touchgfx) until one day I could no longer erase sectors or full chips (...
Hello everyone I'm working with Uart on STM32F411RE Nucleo board. It gives a code error, but no data is provided through USART2. Can anyone help me with this problem? The code is as follows: void Delay(int time); static void uart_set_baudrate(uint32...
Hello,I have a problem with my microcontroller (stm32f407VGT). The microcontroller runs correctly in our application for 30 minutes or 5 minutes (times are always different until the error occurs). Then suddenly the peripherals no longer work, e.g. n...
Hallo,I struggled already two days with the implementation of USB_OTG_FS on a STM32F401 board. The most prominent error concerns the Virtual Com Port on the Windows PC: whatever I try, there is always a message saying "USB device not recognized", wit...
Hello, I hope you are well.I'm working with a project, where the base code is the example "STM32CubeExpansion_Cloud_AWS_H5_V1.0.0", I need the current time somehow. So I thought about SNTP, however, I don't have much knowledge on the subject, I would...
Hi Team, I want to work on USB PD sink , which board would be suitable?, I'm trying for 28V 5A power. I think the firmware for this specification is not available yet. Even though i want to try on. Would you suggest me any board? Is STM32L562 would b...
What code works for the STM32L412 device?I want to load an RTC calibration value into flash memory and retrieve it on subsequent running of the firmware. I've got the reading of specific calibration values working in a different IC, for ADC calibrati...
