If you put an MCU in sleep mode with WFI, such as the STM32L452, you are supposed to suspend the SysTick and resume it after. Usually this is done in the main thread context. However, when you have an interrupt, I believe the next instruction will be...
Hi, I'm programming an STM32F030C8T6 MCU. When I attempt to upload my code, it gives me an error: "Could not halt device (19)". I noticed that this only happens when ADC is enabled from CubeMX. When I disable it, everything works fine. The code doesn...
Hello,I am working with a custom board communicating via USB-2-USART IC (FT234XD-R). Upon power up, the board operates as expected. I can communicate with the device . After some time--usually 60sec or so, but not perfectly periodic-- the device will...
Hi All, I managed to be able to bootload the STM32H723 device using the STM32 Flash Loader (STBootLib) but do not like how I have to pull BOOT0 high and also reset the device right before I program the device and then when the boatloading is done res...
Hello,I wonder if someone has knowledge about any difference in how variables are initialized and handled when launching an application from CubeIde vs starting up the MCU.My case: I use a STM32H7 and the application runs regularly when I launch it f...
Hello, I have a set of extended CAN ID's I need to pas the bxCAN filter. I looked at some examples where one ID is passed the filter, but could not figure out how to allow a set of ID's. If my understanding is correct the mask is used to determine wh...
Posted on October 09, 2016 at 20:03Hello,I'm building an application with ST STM32L4 that stores information on internal flash (ECC flash on L4). The information is valuable, so the flash programming must be robust to unexpected shut downs including...
Good Morning Ladies and Gentlemen, Could you communicate in a short way the size of the contact drill-holes (stm32f411 - CEU) ?The diameter in AWG size would be enough.We also are interested in further documentation-links regarding it. In student wor...
Hi all, The STM32L412xx and RM0394 are quite clear about current use of the micro when in standby mode with LSI-RTC.One thing the docs are not so clear about is the effect of having combined VBATT and VDD pins on the low pin-count packages. With thes...
Hello,I'm having issues with software behaving inconsistently and freezing when I add certain lines, try to access certain variables, etc. I suspect maybe it has something to do with the restricted flash regions in the MCU. Is there any way around ...
