Resolved! Changing PWM frequency with potentiometer
Hi everyone, I am trying to generate PWM signal and change it's frequency with a potentiometer. I have connected an LED to the PWM output and it blinks only a few times and then stops. Sadly, I don't have an osciloscope to check the signal.I am using...
Resolved! Can LSI oscillator be disabled once the IWDG has started running on STM32G0 ?
In my application I have configured IWDG to start running.I would like to prevent the IWDG from resetting the MCU while in stop 1 mode for extended period of time.In the reference manual it says: "Once running, the IWDG cannot be stopped." But in the...
Resolved! STM32 series PWM out logic level at reset and pause state
I am using STM32F103RCTx and STM32CubeIDE for developing a small application.I am tuning a vacuum pump DC motor using PWM signal with TIM1 CHANNEL_1. But I hit a small problem when I start debug the board. The motor is running from the time the IDE s...
Resolved! STM32 H7 - I2S Clock Timing Problems (runs at 1.027 Mhz for some reason) - See PulseView
Hello,Still trying to get I2S working on the H7...Opened up PulseView to check the clock between another connected device...Much to my surprise, the STM32 is actually outputting 1.027 Mhz average clock pulses instead of the ESP32's 1.024 Mhz. Checked...
Resolved! change pins from gpio to uart
Hi everyone!, in my prototype i need some low and high pulse before sending uart datas.. How can i do this? I have already tried using HAL_GPIO_Write and HAL_DELAY and it is not worked.I need an advice for it.Thanks.
HAL_FLASHEx_Erase HardFault_Handler STM32G030K8
Hello,I have developed an application that saves accelerometer data when a machine starts up. This data is stored in the last page of the controller's memory (page 31).I'm encountering a HardFault exception that occurs intermittently, roughly 1 in 20...
Ethernet on custom board with STM32H730
I have a custom board with an STM32H730 and a LAN8710A PHY, operated in RMII mode. The board is a new design, based on an older board but with some differences (the older board has an STM32H750). My short-term goal is to prove out the hardware -- a...
Resolved! UART Receive issue
Hello,I'm struggling with a really strange issue. I'm trying to make UART RX working on a STM32G4 custom board.I've followed the UART Interrupt tutorial. (https://wiki.st.com/stm32mcu/wiki/Getting_started_with_UART)I've tested it with Nucleo-G431RB a...
Resolved! I2C_DR register wont be cleared
I'm using stm32f103c8 and PCA9685 devices. I'm trying to send data to PCA9685 via I2C bus. I send data using I2C_DR register. But when i write a data to I2C_DR register it sticks to it. After the data is send thee I2C_DR register should be cleared bu...
