I am using timer15 to generate TRGO by update event, which is used to trigger DMA to transfer data via spi.From the oscilloscope, I found a delay around 150ns between rising edge of TRGO (PWM output on PA2) and first pulse of SPI sck.I am not sure wh...
Hello everyone,We are using a custom STM32H755 controller board, and we are encountering an issue where the controller locks up whenever we switch the core clock source (for example, switching from HSI to HSE).According to the evaluation board user m...
I am using a NUCLEO-F767ZI Board.Previously I have not used or configured any GPIO. Then I used CubeMX to reconfigure 3 Pins to Inputs with Pull-Down like this: if (HAL_GPIO_ReadPin(button_uncouple_GPIO_Port, button_uncouple_Pin) == GPIO_PIN_SET) {I...
Hello STM community,I have built and assembled a custom PCB board with an STM32U083CC on it. I have made 5 boards, after the first two did not work, I only populated the minimum on the other three. However, I am unable to debug or event connect to it...
Hi Team,We are using STM32G431RBT6, we have tested the ADC1 for PA3 i.e. Channel4 with external Vref 3.3 and VDDA 3.3 with 12-bit selection and the reading we are getting with 5 to 10 counts fluctuations we are seeing but when we have changed to inte...
Hi everyone,I'm currently designing a custom board based on the STM32F722, and I came across something I need clarification on.According to the STM32F722 datasheet, there is no device listed in the UFBGA176+25 package. However, when searching online ...
Hi everyone,I have a program with UART communication using interruption and SPI communication using DMA. I realized that when I send a lot of data through SPI, sometimes I get the DMA error code in UART, but I didn't enable DMA in serial. As far as I...
Hi all. I have encountered one ADC sampling problem in STM32H743. When the signal's amplitude is large, the ADC works fine. However, when the signal's amplitude is low, there are many jitters that I don't want. What happens here? How to fix it? Many ...
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...
