MPU region size [HAL] [L0]
In the firmware package L0 v1.12.0In the file "Drivers/STM32L0xx_HAL_Driver/Inc/stm32l0xx_hal_cortex.h"These are the region sizes defined:#define MPU_REGION_SIZE_32B ((uint8_t)0x04) #define MPU_REGION_SIZE_64B ((uint8_t)0x05) #defin...
Is there documentation on best practices for changing system clock configurations and voltage scaling when an STM32 MCU device is already running?
I am updating legacy firmware running on an STM32L151QEhx to the HAL libraries. Our current firmware changes the PLL (which supplies sysclk) configuration's multiplier and divider and the voltage scaling whenever a USB is connection is detected or te...
STWINK1B connection to a different cloud-based MQTT broker
Is it possible to connect the STWINK1B to a different cloud-based MQTT broker (personal AWS account for example)? If so, can you advise on how this can be done?Is it possible to attach the STWINK1B on the nRF Cloud which is also on AWS?Finally, is it...
How ADC Works Without GPIO Pins ?
Hi All,I am working on ADC with multiple channels Interrupt method using NUCLEO -L4R5ZI- P(STM32L4R5ZITxP). ADC working for all channels irrespective of GPIO Pins.for example, I Commented GPIOA( Port A and its clock) highlighted in bold color even th...
DMA for controlling GPIO output is not working on STM32H7 devices
I am trying to use DMA to control GPIO port E output.Below is configuration of CubeMXIn Cortex-M4 context of dual core , DMA is successfully working to toggle GPIO Port E output .But In Cortex-M7 context of dual core , although error message, DMA ...
Resolved! Why cant i write into mem 0x40026410?
stm32f207zg (nucleo-f207zg)Hi, im trying to write into my DMA2 Stream0 CR register (mapped as 0x40026410).But that memory addr cannot be written not with my init code nor manually trough the STM32IDE debugging tools .Is there any memory protection or...

Resolved! how to disable/enable all the interrupt of STM32L4xx by STM CUBE
Posted on August 09, 2017 at 04:53I just wonder how to disable/enable all the interrupt of STM32L4xx by STM CUBE.I found this not mentioned in the CUBE hal UM. I appreciate if someone can help me for this.
How to retain RTC internal time on power reset(STM32f103c8t6)
working on STM32f103 want to hold time on power reset, not able to do it so,used backup register to write the data,HAL_RTCEx_BKUPRead(&hrtc, RTC_BKP_DR1);HAL_RTCEx_BKUPWrite(&hrtc, RTC_BKP_DR1,0x32F2);any suggestion would be great....
