STM32L431RCT Hard Fault on SPI at HAL library
Hi,I keep on getting hard fault on HAL_SPI_Transmit_IT.I am trying to communicate to SX1276. The circuit is designed by another experienced hardware engineer.I use the similar code on STM32L431CBT without issue.However, I face random hard fault on ST...
Pin PC13 in input mode with pull up option does not drive the pin high.
Hi,I am trying to configure the pin PC13 in my STM32G473VBE6 device as Input with Pull up option.There is a sensor connected to it, so when it is activated it will pull the pin low. But after configuring the pin PC13 to Input with pull up. I am seein...
What are the important files to push to git?
I had a project and pushed it up to a github repository that I just created. STM has so many files under many directories (CMSIS, etc.) I didn't feel it necessary to add all these files. I added the .ioc and all my source and header files. What o...
Resolved! STM32H753ZI DMA Handler stop working when switched from C to C++
Hi everyone, just a question about this DMA not triggering for unknown reasons. The only thing I can deduced is the switch from C to C++ and how variables behave within an object maybe. All I know is the peripheral is working and the DMA is setting t...
FUOTA: Facing issues while using flash memory instead of UnfragmentedData[FRAG_MAX_NB * FRAG_MAX_SIZE] (SRAM buffer)
Hi,We are using B-L072Z-LRWAN1 board to perform the FUOTA.The way we changed the current implementation:1. In FragDecoderWrite function in main.c we added a function to write the fragments to the flash memory. FlashMemHandler_Write((void *)(FLASH_BA...
Resolved! Can we output the RTC calib on pin PE3 on STM32L0 ?
i have a STM32L0VZ (UFBGA100) and I would like to know if I can ouput the RTC Calib on this PIN ?Thank you very much
Can any of the STM32H7 2 Kbytes (64 Flash words) of user option bytes be used for application configuration parameters
A similar question has been asked a few times on here. But I have yet to see a clear answer.In the document herehttps://www.st.com/content/ccc/resource/training/technical/product_training/group0/1f/4f/b7/85/91/e0/4d/2f/STM32H7-Memory-Flash_FLASH/file...
How to capture NDTR of ADC DMA on timer event
Hi,on H723... I'm trying to configure a DMA on TIM5 CC3 event (DMA1 Stream 0 P2M) to capture the current NDTR value of another stream (DMA1 Stream 1 P2M) (to record where that DMA just put data from ADC into a ring buffer at the time of the CC3 event...
STM32F405RG 시리즈 문�?�
안녕하세요.기존�? 사용중�?� 시스템 (PIC 계열) �?서 MCU 만 �?체를 하여 사용�?� 하려고 합니다.기본 Digital I/O 신호가 5V �?��?�요.STM32F405RG �?� Datasheet 를 보면서 �?금�?�?� 있어 문�?�를 드립니다.I/O structure 가 FT �?� 경우, 기존 사용하면 신호를 그대로 연결�?� 해�?� 무방한지요?아니면 Level shift 회로를 추가하는게 좋�?�지요?
