Does the current consumption of the micro stm32L151 in stand by mode with the RTC enabled vary with the supply voltage?From my tests I find that by powering the micro with 3.1 V I have a current consumption of about 4 microA while if I power it with ...
Hi,I am using FMAC for STM32G4.I can't find an example FMAC_IIR_DMAToDMA.I tried to configure a DMA instance for Input but the example was not working.1- Besides the DMA instance, should I use 2 more DMA instances, one for input and one for preload?2...
Hi, We are designing a low power design using STM32U5A9NJH6Q. As it is low power we aim for lowest possible consumption.We are not using USB on the device; hence we would like to omit any consumption from the VDDUSB and would have connected it to VSS...
When I use STM32G474 for SPI communication and configure it to host、 Received only mode, and use hal_spi_receive_dma() to start communication，the number of clocks is always one byte more than I want.For example，if i want to receive 3byte data and con...
Dears, I have issues with setting RTC shift register.I have setup RTC with AsynchPrediv = 127 & SynchPrediv = 255 and is working normally.I tried to periodically setting RTC->SHIFTR with value 100 each 5 secs. Then wait for the shift operation to com...
Hi, I am interfacing an ENDAT Encoder with Stm32 microcontroller, Actually my board is controlling motor as well with timer interupts . So I need to ask My code is a function having for and while loops in main().When Motor control side Interupts occu...
Hi,Anyone can help with resources (videos, Documents), to understand how to calculate time delay and execution time for CAN messages and SPI communication. I am working on STM32H7 MCUs and need to get a close estimation about the time delays, for exa...
Hello, I have a CAN 2.0 network (classic can) running at 500 kb/s. I have multiple STM32F4 nodes running the stm32 HAL CAN driver with no issues. I have another node running a STM32G4 with a FDCAN driver set to classic mode. When the G4 node is co...
Hi everyone,I am trying to power my NUCLEO-H563ZI with an external power supply. I have tried everything in the documentation (jumper positions and pin connections) including a 3.3v input (3.3), a 5v input (E5V), and a 9v input (VIN). None of this wo...
Hi, I`m new to MIPI DSI, and still learn how to use it.Recently, I develop with my custom board and start with MIPI interface display. Then config with CUBEMX, but after compile program, it always stuck in HAL_DSI_Iinit while loop below /* Ge...
