SPI communication with AD9959 4 channel MSPS DDS analog device
Hi, I'am currently working on implementing a driver with the AD9959 with the stm32G474re discovery board, I am able to write to all 4 channel to generate any frequencies with any phases with the SPI module, but when I'm trying to read, HAL_SPI_Receiv...
Resolved! Multiple value for VECT_TAB_OFFSET on STM32H7
Hi all, we've been developing some applications using STM32H743BG since 2020 and only now we realized that value of VECT_TAB_OFFSET has been changed according the package used in STM32Cube. So, these are the differences between different Cube version...
STM32H735 ADC DMA Ethernet memory issue
HiI have implemented ADC1 on a DMA and verified its operation. I then implemented the ethernet stack and verified that it can be pinged. The issue I'm having is that the ADC DMA stops working once the ethernet stack is implemented. I believe the erro...
Getting HAL_ERROR while using I2C in Fast mode pulse
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 ...
Systick is not triggered and Interrupt handling problem in STM32WB55 series
Hello, I am trying to built an applicaiton on STM32WB55 MCUs that contains interrupts and many digital signals. My code working very fine on development board and I am trying to implement this code on custom STM32WB55 PCB. The Problem is vect...
nucleo-f103rb canbus problem
Hello,I have a problem with canbus on nucleo-f103rb. When I start the debug the registers look like before.png. After a while its look like after.png. But i cannot send any data to peak pcan in both cases. Here my code;/* USER CODE BEGIN Header *//**...
Difficulty with speed of updating PWM duty cycle
Hi, I'm a relatively new programmer, attempting to program a "Bluepill" module, which has the STM32F103C8T6 microcontroller. I'd like to be able to quickly change the duty cycle on a PWM output, so that I can adjust the position of a servo motor as I...
ThreadX makes HAL_Delay() & HAL_GetTick() functions highly unreliable
I have set up ThreadX on my STM32U5A9 board using CubeMX. In such configuration it is recommended to use SysTick for ThreadX and select some other timer as a Timebase Source so I selected TIM7.Now HAL_Delay() and HAL_GetTick() functions are very unre...
How to call ITM_SendChar with STM32H755 dual-core MCU, but on CM4 side.
Hello all, I am new for STM32 dual-core MCUs(Nucleo-H755ZI-Q is used). By following the guides(reference manuals, application notes...) I have been successfully sent characters to SWO with following call graph on Cortex-M7: ITM_SendChar() <- _write...
