__disable_irq() in ISR possible?

Hello,I have a global variable, wich is accessed by multiple ISRs. Can I safely disable and re-enable the interrupts within an ISR using __disable_irq() and __enable_irq()?Or is there a more elegant way of protecting the variable access?best regards,...

STM32L4 serial communication doesnt work!

hey,i have an STM32L432KBU6 and i want to serial communicate with my chip. I connected the SWCLK, SWDIO and the SWO pin and followed a couple tutorial on youtube but i just cant get the Serial communication done. i just want to open serial monitor li...

I am unable to configure CAN in STM32L476VG Discovery board. I wanted to develop an application which sends CAN message and receives CAN message. I enabled 2 interrupts CAN1_TX_Interrupt, CAN1_RX0_Interrupt. I selected Normal Mode only .

When debugging I found that MX_CAN1_Init() is not getting initialized, inside this code HAL_CAN_Init() is blocked by a while loop.That blocking iteration is as follows/* Get tick */ tickstart = HAL_GetTick(); /* Check Sleep mode leave acknowledge */ ...

Trouble to install the ST link USB driver, it is not installed in the device manager. Jumper JP7 is set to STLK, LD6 is blinking red, LD5 is off?

MCU locks up the moment a relay closes. Are there any tips to stabilize / make the MCU less sensitive to external noise?

We have a board with a STM32G071RBT6. The MCU is controlling a mechanical relay that breaks mains voltage (230V). When the relay closes, this causes the MCU to hiccup in rare occasions: either the core locks up and the WDI resets it, or a NMI excepti...

About the output specifications of NUCLEO-L010RB

Hello.I am using NUCLEO-L010RB.What I want to do is to monitor the trigger with the GPIO pin during stanby mode, the sequence operation of the GPIO pin at the time of triggering, and the output of 16MHz from the MCO.However, in the current configurat...

NUCLEO-L476RG 2 Images Configuration SE_APP_GetActiveFwInfo() failure

Hi,When calling the SE_APP_GetActiveFwInfo function in the UserApp the NUCLEO-L476RG resets every time without any warning or error.Maybe it has to do something with my linker configuration? There are no problems during compilation.Linker script:/* *...

STM32F446ZE spread spectrum clock generation

Hello,I am looking at the documentation for spread spectrum clock generation and I can't see how or where it should be implemented.Any help or pointing towards the documentation that will explain it would be appreciated.Thanks
