Setting two CAN IDs in the Acceptance filter on STM32G474

I am using the STM32G474E-EVAL1 board and the example FDCAN_Com_polling.It is working and only accept ID of 0x111.The code is: sFilterConfig.IdType = FDCAN_STANDARD_ID; sFilterConfig.FilterIndex = 0; sFilterConfig.FilterType = FDCAN_FILTER_MASK;...

Chip Select for Quad SPI on STM32H7

Hi,I am using Quad SPI on SHT32H7 and I am looking at examples in STMcube. My question is: Is Chip select for the QSPI handled by the port (inside the silicon) once set or is it my driver function that needs to do it like I had to in regular SPI driv...

How can I attend to the workshop wiithout a Teams-account ? WS-preparation was nearly perfect until I went to the point on how to connect to the webinar. I can't believe that you use such a dubious plattform to provide the webinar. Jürgen

DMA transfer in interrupt mode

Hi, in the book i am reading there is an example about UART DMA trasnfer in interrupt mode. In this example i don t understand why the author enables the UART related interrupt.I mean it is not the UART to generate the interrupt but the DMA when tras...

X-CUBE-BLE1 on a STM32L072CZYx

Hello,I am currently working on a project using a STM32L072CZYx MCU on a B-L072Z-LRWAN1 cardboard. I soldered a Bluetooth SPBTLE-RF component onto the board in order to use the X-CUBE-BLE1 software with my STM32L072CZYx MCU. So for my project, I have...

Problem with Network Component on STM32H7 (CubeMX) and Keil

Posted on July 13, 2018 at 18:06Hi guys,I have recently started to work with Keil uVision and I am porting my code that I have previously coined with SW4STM32. I bumped into some problems with the network component (I would like to switch from previ...

I use a STM32L151 in a battery application, i have to measure VCC. To do this exactly i try to read the Vrefint-calibration Value, stored at 0x1ff80078/9 (STM32L151 Datasheet pg. 56) But if i try to access to this address via a pointer, i read 0x0.

Memory Dump with STM32CubeIDE shows also 0x0 at this addess. The Errata shows no entry to this problem.uint32_t* ptr = 0x1FF80078;VREFINT_CAL_VAL = *ptr;Is it a typo in the dataheet?

NUCLEO-H723ZG ethernet issue with Keil uVision5 / MDK-ARM

Hi guys,I started a project on keil µVision5.34 and a NUCLEO-H723ZG board. I would like to implement TCP-IP connection with a computer. After receiving an ARP request from the computer, the microcontroller enters in hardfault_handler. So it doesn't s...
