Hi, I'm using STM32F103. I encountered a problem when using the system timer to generate a delay. The processor runs at 8MHz from reset, well I think, and I'm using that clock to generate a 1Ms delay. So, I've to load the SysTick LOAD register wit...
I'm just setting up the input capture on timer 2, input capture 4. On page 411 of the reference manual for the CCMR2 register and the CC4S bits, it states "01: CC4 channel is configured as input, IC4 is mapped on TI4 10: CC4 channel is configured as ...
I'm dealing with a car and want to use CAN bus while doing this I also want to use stm32 but I have encountered a lot of stm32 and most of them are in Can bus. Which of these is most ideal? What should we pay attention to using the CAN bus protocol?
Hi,I am working on STM32L475 ARM Cortex M4 board and writing code for it on STM32Cube IDE. I want to swap two memory regions of FLASH memory in my BootLoader program when some conditions are met. I already tried swapping using the normal method but ...
In latest CubeL4 v1.14 release notes I noticed this: * Demonstrations binaries are no more delivered within the STM32CubeL4 MCU package. They are available for download, in addition to their required media files if any, in a standalone package access...
In page 233 of document PM0214 saysEach PRI_N field is 8 bits wide, but the processor implements only bits[7:3] of each field, and bits[3:0] read as zero and ignore writes (where M=4).But there is a mistake, it couldn't be bits[7:3] and bits[3:0] at ...
Hi,I'm trying to work with the demo example project of STM32F769I with stm32f767zi-Nucleo board.I'm just compiling the existing code but either i'm not transmitting data nor receiving data.Is there anywhere i need to do any changes with the configura...
Hi all,I'm currently looking for a low-power-consumption MCU which integrates camera and wifi interface. It would be better if the MCU gets the wifi module inside. Could you give me somesuggestions?Thanks in advance!Br,Mark
In documents and lots of online sources there is a formula as follows(attached below),But I cannot get why CAL value is in the numerator and RAW data is in the denominator. I have this logic in my mind,In the factory, producers used a preknown/fixed ...
Hi,i am a new user and bought the STM32F756ZGT6 Nucleo-144 board for the university.I tried to use the CMSIS-Function to do a real Fast Fourier Transformation on 1024 samples values. I created a new Project using dma for fast sampling. When I add the...
