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...
Hello guys, i am using the code below (input capture mode, timer 3) because i need measure the high and low pulses, but i am not sure how to know which edge generate the interrupt, i have configured the timer with both edges, but in the interrupt cod...
Hi im trying to develop a bit of error management in my canbus driver.I noticed there is an ErrorCode inside the canbus structure. That error code could have any of these values: But it turns out the hcan.ErrorCode is always HAL_CAN_ERROR_NONE, even...
I am using the timer interrupt and currently, it has priority 3 once I get into the ISR then I want to change the priority to 2. I have used like below but the priority not changing.NVIC->IPR[6] |= NVIC_IPR6_PRI_25 & 0x22222222;__dsb(0);In above, __d...
Here's the error that I get:"c:\st\stm32cubeide_1.9.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\bin\ld.exe: cannot use executable file '../../../../../Boo...
Probably no and this is probably documentation flaw across all STM32 RMs.JW

I'm using STM32H743 I2C1 and FW as of december 2021.I'm testing in continous loop PMBus communication (straight I2C master interface).Appr. all 8h I'm getting a sporadic bus error.A good transaction looks like:this is a register read (addr-len=1) for...
hi when i use normal configuration for define this pin(PB4 in STM32H743) as GPIO output a problem occurs in the program.This pin is connected to the JTAG port and i use only SWD mode and pull up this pin by 10k to VCC.plz help me to config this pin a...
Hi,I have two questions regarding STM32H750:1) I would like to pre-burn its internal flash with a simple code that enable XIP (execute in place) from external SPI flash and jump to some initial address on this external flash. Then I like to permanent...
I am sending a fixed-sized buffer (512 byte) at 8 Mbits/s via UART out of an STM32F3, and I am experiencing what it seems to be a fixed delay (~ 2-3 bit periods) between consecutive frames. In the screenshot below, after sending the dummy value 01010...
