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...
rtc year is uint8_t, does anybody know how to identify year less than 2000 or more than 2000?Regards,
Hello. I try to calculate some pulses by wakeups from shutdown mode. I have 2 pins which areWKUP1, WKUP4. They are configured to wake up by rising edge. But sometimes when only 1 of them is rising, I receive 2 notifications, from both pins.The proble...
I'm working on a project for a battery charger and for safety purposes I want the complementary outputs of the HRTIM to be disabled when the core is halted. On the STM32F334, setting the HRTIM_STOP bit in the DBGMCU register resulted in both the HRTI...
