I am trying to call rtc alarm at regular interval and want to call some code in non polling mode at every rtc alarm is fired. I know this can be done with RTC alarm callback function. But when we are in standby mode this call back function is not fir...
This is the code I'm using to read the page of 16 data chunks of 256 bytes each:#define K9xxG08_ECC_Enable() FSMC_NAND_DEVICE->PCR2 |= FSMC_PCR2_ECCEN #define K9xxG08_ECC_Disable() FSMC_NAND_DEVICE->PCR2 &= ~FSMC_PCR2_ECCEN #define K9xxG08...
Hello guys good day. May I ask for your advise regarding the code to interface a slave bluetooth to STM32F103C8. I bought this HC05 module and connected to the UART lines of the MCU. Baud of communication set to 9600. I am trying to enable an LED con...
I am using the Nucleo-L4r5zi with the octospi peripheral to communicate with a qspi NAND flash chip (W25N01GVZEIG). The octospi peripheral is set up in status polling mode to poll the state of the Write Enable bit in the flash status register. This i...
That is my code below (Nucleo STM32L053). RTC works from 32768 quartz (LSE). Blue Button disconnected by eliminating of the SB17. Additional LED is connected to PC13 instead of the button. So, the device wakes up normally, when I set high level on wa...
My controller can be waked up from Standby mode by Alarm A or Alarm B: Alarm A every day and Alarm B every minute. Are there any flags (or another means) to know, what event (Alarm A or B) was cause of the waking? That is the problem, because all re...
according to the manual it says 4 Kbytes of backup SRAM in D3.D3 start address is 0x38000000in manual address for backup RAM is 0x3880 0000but below is the behavior observed.code example. __HAL_RCC_BKPRAM_CLK_ENABLE(); HAL_PWREx_EnableBkUpReg(); HAL...
Hello,I have generated a default project with cubeIDE for a nucleo L433RC. I have only enabled LPUART1 with default parameters. I just change the baud rate to 115200.I add in the main : /* Infinite loop */ /* USER CODE BEGIN WHILE */ char out[6...
hi, Reading the UM2397 manual on page 12 chapter "Power supply" describes the possibility of powering the core through Vin in a voltage range of 7V-12V, I power it at 10v (the power supply can supply 500mA sufficient current for a core). The card the...
I am planning to interface 4 numbers of Wiz830MJ modules with STM32L496 using FMC SRAM interface. Is there a need to have buffers for address bus and transceivers for data bus. OR else Can i manage without these buffers/tranceivers ?
