Hi, I'm working on an STM32H7 project with very fast (800 KHz) periodic interrupt. I've been looking at the generated code as I tweak the C source. I'm confused about the use of "volatile" for the global variables used by the ISR.I feel like I need...
stm32f103cbt6, i2c1 in slave receiver mode. CubeIDE, stm32f1 pack ver 1.8.4. I use HAL_I2C_Slave_Receive_IT to receive 1(adr)+2 bytes. I2C standard mode. Both err and evt interrupts enabled. I2C stucks into bus error (BERR flag). Jumping over HAL co...
Hello, is there a way that a timer triggers an I2C-Receive with a Datatransfer from the Peripheral to memory via DMA?I’d like to have no “Timer-Interrupt�? that calls the DMA-Transfer, invoking the I2C. I’d like to drive the DMA-Request from the Time...
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...
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?
