Hi,I am using stm32h745zi controller in my custom board. I want to use uart in DMA mode.When i send data through uart i got an interrupt only for first time. How can i get Interrupt everytime. and how to use uart DMA in both cores(Both tx and Rx).
Hello,I am using a STM32L081KZT6. My code sends a Message via LPUART every second and receives an input over the same LPUART from the user. The RTC is used for the timing with LSE. To save power, I go into sleep mode between sending and receiving. Th...
Hi Community,I worked on project W25Q01JV (QSPI NOR FLASH) interfacing with STM32F769AI . I have fully functional project with Erase, Read and Write. Now I am trying to do following tasks :1) Configuring into Memory Mapped Mode.2) Implementing an Ext...
About one year later,my hex file doesn't work after downloading to MCU(STM32F103C8T6),but every use is normal throughout the year,the hex file has no changes.but it's OK to regenerate ithe hex again.Why?
We are facing problem with USART in STM32L475RCT7 microcontroller. Recently we have migrated an existing product from MCU stm32f103rct7 family to STM32L475RCT7.All code changes are done properly and migration was successful. The product communicates ...
My code was compiling fine, then I turned on the Doxygen setting in preferences. Now i get lots of errors and warnings. My function prototypes say used but never defined. My functions say invalid storage class. I can't find what is broken. I turned o...
A 720mV RMS sine wave, biased to +1.25V is connected to the PB2 pin. PB2 is the COMP1 positive input. The COMP1 negative input is connected to the internal reference voltage (+1.22V) The output of the comparator is connected to PA0 which is the input...
Hi STM Community,I have interfaced External Winbond NOR flash to STM32F769AI through QSPI. Write to memory and read from memory is working for less data. But for lengthy data write and read operations are not working.
