The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi,I have a very specific question regaridng the functionalities of the STM32L4's internal bootloader. We are using its functionality to flash and validate our targets according to AN3155 and AN2606. This operates quite well. But now we came into the...
Hello there,I was trying to figure out a way of how to change the UART baudrate "in runtime" via HAL API for stm32f0. I failed to find a way to do it other than manually (copy out the functionalities used in the uart init function and change it accor...
In my customised board i am transmit "Hello World " via default arduino pins PA10=D0(Rx) and PA9=D1(Tx) named as USART1 using FTDI232 (USB to serial UART interface) and showing the trasmit data in the serial monitor properly. In my code i have writ...
I am using STM32L451RCT6 MCU . When I take a fresh MCU , unprogrammed and flash it for the first time , the flashing fails and when we flash it in the subsequent boots, the flashing succeeds.Can you please let us know , if we need to add any addition...
Has anyone encountered this problem? An ORE error occurs when receiving data with LPUART. After I clear it with software, an ORE error occurs every time I receive data. How can I solve it?
Hello,I've got a very basic setup for an STM32G431KB/STM32G441KB where I use default interrupt priorities (verified all 0 in SBC and NVIC) for each exception in the vector table. I would therefore expect that a SysTick exception (-1) would preempt an...
The MCU of STM selects the external crystal, whether to choose a high frequency or a low one, what are the instructions?For example, for stm32L486, the datasheet gives the maximum main frequency as 80MHz, so 4Mhz, 8Mhz, 16Mhz, 20Mhz, 40Mhz can be rea...
CAN_ESR_LEC =0x05.which means bit dominant error, CAN_MCR_DBF bit is at 1.how to trouble shoot it
Hello, teachers. I'm an introductory to stm32.I am posting like this because there is a situation where communication is not possible while communicating i2c between stm32.This is the current structure.STM32F103VE Use 1 Master, STM32F302CB Use 5 Slav...
