I am using STM32H7 HAL_SPI_transmitreceive_DMA, where are all internal buffers and how to refresh data?
Hi,I am using an STM32H753 connected to a raspberry PI via SPI. The STM32 is connected as slave. With CubeMX I configured the STM32 to be an SPI Slave with both DMAs configured as circular. I am having a struct with live data (refreshed every 10ms) a...
Resolved! Interrupt not triggered on EXTI1
actually I'm using stm32F446RE, I'm using hal library just to detect external interrupt from PA1 pin but it doesn't work, and if I put the interrupt from PA0 pin, it works fine?/* USER CODE BEGIN 0 */ void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ c...
Transfer data coming from different devices
Hi ! I am receiving data from two devices and want to transmit it using usb. I am able to send using usb when receiving (to a circular buffer) only from one at a time but when I receive from both, it doesnt work (a lot of data is lost and I cannot d...
What is the magnetic field sensitivity of the stm32f030c8t6?
Using this on our board and have noticed it slowing down with increased use, just wanted to know if its potentially the magnetic field but I can't find the MEF for this board
FMAC control loop issue at lower temperatures
Hi,I am currently working on a synchronous buck converter (24 VDC in and 1-15 VDC, 1-15A out) for which I used the HRTIM of the STM32G474 in combination with the FMAC as a control loop:I mainly followed AN5496 and AN5305 to get my converter up and ru...
Flashing Nucleo-L073rz using the system bootloader.
Hello, I have the project in which I need the flash the stm32L0 with uart using the system bootloader. I have settted required option bytes. I make the boot 0 pin high and the sytem is getting into the bootloader mode. I attach the usb to uart conver...
How to calculate ADDSET and DATAST according to SRAM timing graph?
I use FSMC in STM32F407 to access external SRAM IS62WV51216. I read RM0090 and AN2784, gives me two fomulatSU means here is the timing graphhere is write timing graphwhy WE have two falling edges on the leftwhat dose tSU tV mean,where is it in the t...
Multile definition Error
I am developing my own driver for a STM32 MCU, however I always get the same error when I try to compile the code. Here is the entire code from all the files I developed.There are always 8 errors, saying that pGPIOA, pGPIOB, pGPIOC, pGPIOD, pGPIOE , ...
STM32U5 MCU FFT Performance Testing
I'm using a B-U585I-IOT02A discovery kit that that has the STM32U5 MCU. I'm looking to evaluate if the STM32U5 MCU can run an FFT in real time and how to evaluate the performace of the STM32U5 MCU running FFT's. Are there any tools to help me do that...
