Hi every one .I have designed a new MCU circuit board for my own purposes. I am using an stm32u575VGTX MCU in this circuit board and for the first thing i need to send and receive data with UART .As i don't want to busy the CPU just sending and rec...
I use the USART1 on a STM32F103RB in half duplex RS485 configuration.My question is: how can i be shure, that the bus is idle?OK, i can see RXNE if a complete Byte was received, but if the USART is just receiving the bits and it has not reached the s...
I'm trying to develop a bootloader for a dual core STM32H7, running on the CM7. I'm starting by trying to modify my user project for it.I've moved the user code up a bank:FLASH (rx) : ORIGIN = 0x08020000, LENGTH = 896K and put in a IVT offset on ...
I am working with a Nextion display and a STM32F411CEx on STM32 Cube Ide I need to both send and receive serial commands to the display at 9600 baud with standard serial port settings. I have no problems sending data to the display but I seem to have...
Hi, I have a board with STM32G071KBU6N with new and empty flas.I have difficulty programming it because it seems to set some pins as output after power up. for example PA6 and PB7. This is causing a over current in the circuit.I suspect some kind of ...
Hello,Is there anyone who worked with TRACE ? I use j-trace with stm32h743 and IAR.On testing the trace with SEGGER cortex-m reference board (stm32h7407, which comes with the j-trace product) and IAR, the functionality works great.I then moved to stm...
Hello, I am writing about my confusion in "STM32H742, STM32H743/753 and STM32H750 Value line advanced Arm®-based 32-bit MCUs". According to reference manual;STM32H743xI has 2 banks of 1 MByte each forming a contiguous flash memory area, so there woul...
I want to use the STSPIN32G4 for an application with a motor voltage of 6-8V. Has anyone ever ran with this low of a motor voltage. The specifications list the minimum motor voltage of 5.5V, so I believe it should be possible. However, the lowest b...
i have a question regarding the correct way of reading the timer counter registers.I learned not to read timer couter registers asynchronously, because it can lead to spourious wrong values if i read just when the timer changes it's value.In several ...
Hi,depend on reference manual RM0433 Rev 8 for STM32H743 p.56.5.7 "FDCAN nominal bit timing and prescaler register" the CAN bit time can be programmed max. 81 time quanta. Is documentation correct on this place?Due to described time quantum range [1....
