Resolved! international oscillator accuracy over temperature range
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 ...
STM32F746-Disco - QSPI Failed to initialize external memory inside Cube IDE but all there are no problems using ST-LINK
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...
Resolved! call RTC Alarm callback function when waking up from standby mode?
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...
STM32F407 4GB NAND Flash ECC computation while read and write are different, but the data is the same.
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...
Resolved! STM32 and HC05 Bluetooth code
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...
Problems when polling for Write Enable bit in qspi NAND flash status register
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...
Why STM32L053 does not wakeup from ALARM in STANDBY mode?
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...
Resolved! How I can distinguish, ALARM A or ALARM B waked up STM32L053 from Standby mode?
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...
