I am using output compare with TIM3 on a STM32H755 I am able to use Output Compare to generate a single pulse on pin PC7 using TIM3, Channel 2.I am using Active Level on Match.I call HAL_TIM_OC_Start(&htim3, TIM_CHANNEL_2) onceAfter 0.5s, it detects ...
I am working on a custom board and I have noticed that whenever the device resets, it becomes unresponsive.The reset causes that hang the microcontroller:Calling NVIC_SystemReset from firmwareHaving firmware stuck and receiving a signal from IWDGManu...
I am trying to configure the STM32L4A6 to act as an I2C slave on its I2C3 peripheral (PB4 - SDA, PC0 - SCL) with 7-bit addressing (address 0x42). The master is a Raspberry Pi CM4 configured on a software-defined I2C bus (i2c5, using GPIO10/11).Both d...
Hi All,I have a system with 2 SPI masters and a single slave very similar to this post from 2014:https://community.st.com/t5/stm32-mcus-products/spi-multi-master-mode-with-stm32f050/td-p/502107What I would like to do is to temporarily isolate the STM...
I have a custom designed PCB board where I have used STM32L56 and W25Q256 along with other components. First, I was using SPI for interfacing but it was taking so much time when writing/reading MBs file. So I have to opt for QSPI now. L5 doesn't have...
Hi Support Team,I am currently using the STM32U575ZIT6Q MCU for development.As per our project requirements, I need to count six independent external pulse signals (from a wind-turbine RPM sensor or similar) with a maximum frequency of approximately ...

I have a Nucleo-H723ZG board. The GPIO lock bits are set at reset so I cannot set up the ports. See Attached screenshot. I can run code just fine and the original demo code did toggle the LEDs. Am I missing something here?
Hello everyone, I have a problem with the bootloader of the stm32h503 microcontroller. I can't get a response from the stm32 via any of the UART interfaces. I tried different baud rates (9600,57600,115200) but I don't get an ACK from the STM32H503 in...
First of all, this problem is related to ADC and OPAMP, in the program I designed to enable adc1 and adc2, as well as opamp2 and opamp6.The clocks of ADC1 and ADC2 come from the output of the PLLP and each set the same sampling time. The TRGO2...
