Regarding Auto grade Controller in stm32h7 series
Hello everyone, I want to work on STM32 series of controller which supports 480MHZ or above clock rate and Auto grade temperature range(I.e Grade0: -40degc to 150degc (or) Grade1:-40degc to 125degc).We found STM32H7 series which supports our applica...
Phantom external interrupt issue with STM32F469AI (custom board)
I am witnessing interrupts on EXTI9_5 line which have absolutely no electrical stimulus. I'm seeing this behavior consistently on multiple chips so this isn't a one-off.The GPIO in question (ONE_WIRE_PIN) is PA8.GPIO initialization here:mIRQConfig.Pi...

I want to know how to read and write data on gpio pins of STM32F103C8T6(BluePill).
I am using keil to program STM32F103C8 MCU and I have the the library files for GPIO read and write functions but it is not working. There are no errors. I am just not sure about the parameters I am passing to functions. I have attached the code and...
Resolved! STM32F769 Discovery kit demo firmware
Hi,I ran several test and example projects on the STM32F769 Discovery platform. I would like to reload the original demo firmware. According to the documentation, it should be available from the www.st.com/stm32f7-discovery webpage but I cannot find ...
STM32F103C8T6 dev board RTC AsynchPrediv = RTC_AUTO_1_SECOND not work correct
Here is my boardhere my clock settingI use CuceMxIDE, here my RTC settingif AsynchPrediv = RTC_AUTO_1_SECOND;rtc take very long time to increase one second. I try some value, and choose 50 and seem the time count rightAsynchPrediv = 50;but I'm not su...
STM32F205 uses TIM_DMA_Update event of timer 8 to trigger DMA2 circularly. In fact, DMA only executes once？
STM32F205 uses the TIM_DMA_Update event loop of timer 8 to trigger DMA2 transport, which moves 5 data from test_data to dest_arr at a time.Using DMA2_Stream1_Channel7, start these two functions in the main program, configure DMA and TIM8, and then ob...
STM32H7 SPI RX DMA not working - bug in HAL?
This project uses STM32Cube_FW_H7_V1.3.2.On STM32H7 I'm using DMA for SPI transfer. I use SPI1 and SPI4, both in D2 domain, together with RAM_D2.In the linker file I added:.dma_buffer : { . = ALIGN(4); *(.dma_buffer) } >RAM_D2The ...
STM32L4xx I2C Interrupts
Please can you help me. I cannot use the HAL as I have to write an ultra low power/ minimalist application. I need to Tx/Rx a few bytes over I2C3 . I have set it up as below but I do not get any interrupts, either event or errors. Can you tell me wh...
