Hi All,We are planning to use STM's STM32H750VB in our design.We need 1 QSPI port from the MCU.We saw in the reference manual following 2 things: 1. In block diagrams (page 883) it is mentioned as if we can enable dual-flash mode (8 bits) and disable...
Hello, Thanks for wonderful support I am working on STM32F407X mcu DMA program and want to understand when will DMA underrun and overrun happens. This is not explained in any of the ST documents even though the RM mentions this>>>>>>>>>When burst tra...
I'm using the Nucleo H743ZI2 right now and have mostly just been using the pins accessible through the ZIO connectors (CN7, CN8, CN9, CN10). I'm wondering about the main purpose of the Morpho connectors (CN11 and CN12). I've noticed most of the Morph...
Hi guys, for some reason I can't this working for the life of me.I am trying to implement a DMA with Uart Transmission with a one shot, reason being is that I noticed with the DMA on circular mode it just transfers whatever is in the buffer even ther...
The steps that I followed :1. Configured micrcontroller added UART Rx, UART Tx and Serial wire Viewer 2. In main.c in the infinite while loop added (HAL_UART_Transmit(&huart2, "HELLOWORLD ", 12, 100) ../Core/Src/main.c:100:35: warning: pointer targe...
Hi,I have a problem to generate a code for MKD or IAR EWARM on CubeMX.I have a NUCLEO-H755ZI-Q development board.I can generate the code for others MCU or Nucleo Botrads, but i have seen that this problem is only related to any MCU with dual core lik...
Dear All,I am working on a new design with STM32F745 and an external ADC of 2-3 Msps range.I have two ADCs candidates: LTC1403A (14 bits/2.8Msps/SPI) and AD7274 (12bits/3Msps/SPI). Please find attached datasheet for your reference.The maximun SPI fre...
i m writing data in 1 bit mode or 4 bit both have the same speed, i m using stm32f746g discovery board. and what can be the max read write speed?
I have the STM32G030K6T.Connecting a magnet to my magnet detector causes HAL_GPIO_EXTI_Rising_Callback and removing the magnet causes HAL_GPIO_EXTI_Falling_Callback. I think I have too much code inside these functions. Inside these functions I'm fadi...
