Hi guys,The STM32F072C8 microprocessor has a total of 31 flash pages. Each page is 2 kb in size. Thus, the processor has 64 (2x32) kb flash memory. The interesting thing is that I can read / write on page 63. How is that possible?Thanks.
I've got NUCLEO-F429ZI board and I'm trying to write simple communication via SPI. I've generated code from CubeMX for SPI1, compiled it under Atollic TrueStudio and run. Unfortunately I cannot get SPI working. I mean I have no clock signal on SCK P...

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...
