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...
Hello!How can I configure only the MISO pin in the mode falling edge triggered interrupt input? It's not possible to do it on CubeMX. I tried to change the spi.c file like follows:/**SPI3 GPIO Configuration PA15 ------> SPI3_NSS PC10 ------> SP...
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...
I am using STM32F072RB Nucleo board and in the technical reference manual it is mentioned that "Please refer to the “Alternate function mapping�? table in the device datasheet for the detailed mapping of the alternate function I/O pins.". But I am no...
