Hi,I want to use the RTC timer on the STM32WB to run FreeRTOS in both normal and STOP modes (For HAL time base I use Systick). When the MCU has no work, it goes into STOP mode. If the MCU needs to wake up for timing, like from a FreeRTOS timer, I set...
Posted on February 13, 2018 at 13:16The current data sheet for the STM32F303CC (DocID023353 Rev13) shows on page 80 the characteristics of the LSI oscillator.Its frequency starts from min. 30kHz to typical 40 and max. 50 kHz (all at 3.3V in the max....
When SRAM1 is remapped at 0x00000000 address space using SYSCFG_MEMRMP register, SRAM1 cannot be accessed by DMA by its remapped zero-based address. DMA error occurs at the very first transfer and DMA channel becomes disabled.Steps to reproduce:1. Us...
Hello, I have a question regarding PG pins PG0 to PG10.Can any of these pins (PG0 to PG10) be used to provide a PWM signal at around 20kHz. Thank you in advance
Hi,I stumbled across a problem with the LSI when i realized, that my IWDG was about 20% faster than it should be.The clock is behaving very irregularly, this is more than the deviation in the datasheet. I read out the LSI from PA2 with an oscilloscop...
I'm trying to use the STM32H563 HASH peripheral to speed up sha256 calculations.The examples all use HAL_HASH_Start() to write the entire message at once.However, I'd like to feed chunks of data to the peripheral. The OEMiROT mbedtls sha256_alt drive...
Hello i encountered this error on F072 nucleo board, it was working fine yesterday and todayit couldnt connect up to STM IDE, whats coursing this and how to overcome this issue?Error in initializing ST-LINK device. Reason: No device found on target
I need to determine if the interrupts are enabled at one point of my code but I have not been able to find any reference for the STM32G474. It doesn't look like there is a PRIMASK register which is mentions in another post.I know how do enable and d...
I am trying to provide a clock to PDM microphones using the CKI1 MDF pin, and no clock is being generated. The MDF correctly generates a clock signal on MDF CKI0. The IO configuration for CKI0 and CKI1 is the same (except for the alternate function r...
The micro STM32L072kz supports the OTA (Over-The-Air) method, I would like to perform the bootloader through the main firmware, without the need to use a USB cable or bus, write a firmware that with the help of a 4G modem downloads a new firmware fro...
