STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
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?
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...
