I use stm32l496. before entering the low power run mode I set the output but when micro enter lprun the output is reset.I want to know what the status of the outputs is at low power mode?andcan the outputs be changed or read?thank's.
Is it possible with the 32F769IDISCOVERY board to access the CAN bus of the micro? I can't seem to manipulate STM32CubeMX's Pinout & Configuration to get CAN activated. Ideally, I'd like to drive the display, run LwIP over a fully active ethernet p...
Hello.I am currently developing with STM32L Discovery.In preparation for development, I tried to output using the MCO in order to know the exact frequency of the HSI of the evaluation board used.By operating MCOSEL in the RCC-> CFGR register, MSI and...
Hello,I have a doubt regarding DMA memory to peripheral ?Suppose I would like to transfer a memory buffer content to SPIx TX.When do each transfer occurs ? Every time I change the content of the memory buffer ? Always ?I cannot find this information...
Hi,When looking into stm32l4xx_hal_sd.c, I observed the following code: if(hsd->SdCard.CardType != CARD_SDHC_SDXC) { add *= 512U; } /* Set Block Size for Card */ errorstate = SDMMC_CmdBlockLength(hsd->Instance, BLOCKSIZE); if(errorsta...
I have a design where I am using both I2C1 (external ADC) and I2C2 (external EEPROM). I have no problem making I2C2 work perfectly. The MCU both transmits and receives messages with no problem and I can see in on the Oscilloscope. However, when I att...
We have the following situation: We want to use the FDCAN of the STM32H743ZI with 500 kbit/s. We've got followingconfiguration parameters for the FDCAN1:hfdcan1.Instance = FDCAN1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan1.Init.Mod...
I want to use coocox os with an stm32l083cz . while i am compiling the code the following error appears. /tmp/ccpwcyyg.s: Assembler messages:/tmp/ccpwcyyg.s:242: Error: selected processor does not support `stmdb R0!,{R4-R11}' in Thumb mode/tmp/ccpwc...
Hi all,To be hontest, I am a beginner when it comes to timer and capture hardware. Maybe someone can help me figuring out what the best way is how I can measure the time between two separate impules i get on two separate lines. Accuracy shall be very...
Implementation on: STM32L476RCI can configure a periodic sleep cycle by waking up through the RTC through calling HAL_RTCEx_SetWakeUpTimer_IT.I'm now trying to handle an EXT interrupt while in this periodic sleep cycle.The goal is to handle the EXT i...
