Microcontroller may be; STM32L0 or L4Required; 5% worst case over -5 to 50'CThe microcontrollers are quoted 1% accurate at 25'C but I can not find how accurate they over the ICs temperature range. I want to avoid trimming or fitting a crystal.The ...
This is my configuration in the include file (settings2.h) with the data to fix in the QSPI during the program phase#ifndef IMG_NO_DATA #if defined ( __ICCARM__ ) #pragma location = ".textqspi" #else __attribute__((section(".textqspi"))) #endif con...
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...
