Hello, I'm writing this in hope I can successfully resolve my issue with getting BERR on every I2C call, when connected with specific master device.I have implemented slave device using STM32F4 discovery board using HAL I2C drivers and IT functions.F...
I have bootloaded a CAN application, and after its loaded & the application starts, it can transmit but it doesn't receive.What steps happen as the bootloader hands over control to the new application? For example, how does it know where to jump to?I...
Hi, I tried to read signal from ultrasonic parking unit by capturing PWM input. Signal has one start pulse 530 Hz width (1.87 ms) and a sequence with 0 and 1 (9.942 kHz and 4,97 kHz) period between pulses sequences is about 193 ms. I use STM32F103 b...
I need to expand my STM32H7A3ZIT6 MCU's RAM and FLASH memories and since I am using a lot of peripherals and would like to avoid the rather complex routing process of the FMC, I am trying to keep the number of pins I am using low thus, I looked into ...
Hi @guru ,In Nucleo-G474RE ,I have connected W25Q16JV in quadSPI bank1 .I have written the Application image binary(.bin) in external flash.I am able to verify the binary written at 0x90000000it in memory mapped mode.When I do Jump to application to ...
I am using STM32s NUCLEO-H755ZIQ board , while debugging through eclipse IDE for the M7 core the board's MCU went under low power state and LD6 which is over current led (red) is turned on.When I am connecting the board with the STM32CubeProgrammer t...
Hi there,here what happened with the second board when I repeated the process.- Generated IOC project with CubeMX for CubeIDE.- Does not link correctly in CubeIDE, had to add "-z noexecstack" C:/ST/STM32CubeIDE_1.17.0/STM32CubeIDE/plugins/com.s...
HelloOn an coin-cell application I use the STOP mode twice, once with WakeUp through external interrupts, once with WakeUp through RTC. Everything works fine.When I enter the STOP mode with WkUp through external interrupts, I need to completely disab...
I could really need some help how to get a STM32F030T4P6 to act as a i2c slave and receive a byte of data I've spend so much time in the past week trying to solve this problem, but no progress at all The final code must act as four PCF8574 port expan...
Hello.An inexplicable bug occurs during the transition from startup_stm32h743xx.s to main, causing unnecessary functions to be repeatedly executed.An unknown function (I2C_IsErrorOccurred) continues to be called. It is strange that it is being invoke...
