Hello ! I've got a problem because I tried to check the SDA and SCL pins like in the picture : Sorry for the paint picture (the oscilloscope was during classes so I don't have it right now).The output was all the time noises even thought the code wa...
Hi everyone,I am trying to implement a system that counts pulses that can be as narrow as 20 nanoseconds using an STM32F746 MCU clocked at its max 216MHz.The first thought was: "Can such narrow pulse even be detected by the MCU?"To confirm, and inspi...
Hi,I'm using STM32H743ZI with STM32CubeMX 6.9.2 and STM32CubeIDE 1.13.1.I added new STM32 project using the CubeIDE GUI - selected the STM32H743ZI device and automatically the project was generated, I opend the IOC file and enabled the ETH + LWIP opt...
I am working with STM32H747i-DISCO board and I configured ADC1 with DMA1 stream0 and ADC3 with DMA2 stream0 both with Cortex-M7 core as initializer and I created the MDK-ARM project using STM32Cubemx and compile the code in CrossWorks when I debug t...
Hi To what does the revision code correspond?I have not found any clear answer in the documentation.Does a new revision replace the previous one? if so how to know which one is the most recent.
Hello,first of I must state that this is a bare metal project. If bare metal is not your thing then please do not read on. I only use parts of the CMSIS but no HAL and no LL.I have a strange effect when using I2C1 bus with DMA and USART1 with receive...
Hi All,I trying to interface MAX6651 Device using I2C module using STM32F410C8U6 MCU.Device address is 0x36 But when i'm using HAL_FMPI2C_IsDeviceReady(&hfmpi2c1, 0x36 , 2, 100); this API returning the valueHAL_ERROR.Here are some snaps Anybody look ...
Hi all,I am trying to configure burst dma on my board (stm32g474). I have successfully configure the dma for single register, however, when I want to configure dma for more than one register, I failed to do that as it only allow me to fill one addres...
Dear, I currently use a STM32G0B1 on a custom board ans all worked fine until now. My firmware change the options bytes at running to disable the dual bank and using and single bank Flash.At the power up, the firmware check the options bytes and chan...
Hello,I'm currently using the HRTimer (on a STM32G474) for duplicating a input PWM signal. That means that in my case, I have one PWM input coming on 2 events (1 for the rising edge, 1 for the falling edge) and the outputs of the HRTimer B, will be s...
