New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

Interrupt Nesting on Nucleo STM32H745ZIT6 -Dual Core Board: How many nested interrupts can this above mention board handle simultaneously?

If there are more than three interrupts triggered simultaneously in the interrupt service routine/callback, how many nested interrupt the board can handle simultaneously. Or there are some cases of memory stack overflow which can lead to the dumping/...

STM32F7 SAI DMA FIFO error

When using DMA to realize a SAI transmit (double buffer, rearmed in HAL_SAI_TxCpltCallback), I found some very strange behavior.In some configurations, a FIFO error interrupt (FEIF, ref. manual p. 235) happens after a few seconds. The time until this...

STM32 Nucleo-F413ZH: Proper way to start a second PWM (delayed and internal trigger start [both trigger or gated] slaved mode) , on another timer.

General objective: Generate 2 PWM's on Timer 3 and Timer 4 respectively at 50% duty cycle, both with period of 2 seconds and phase shift of 1second between them (Timer4 will start 1 sec later).Because I want it to be precise, I am not considering usi...

double type calculation

Hello.At the next double type calculation,double a = 0.7; char b = 12; double c;   c = a * b;c is saved to 8.39999 in the register But 0.7*12 is 8.4How can I save 8.4 to the 'c' register?Thanks.

Resolved! My STM32L051K8T6 gets stuck in an infinite loop in HAL_Delay(1000); but I know its a hardware problem, not a software problem. Where should I focus my hardware debugging on?

I have used this same chip on a previous project and managed to toggle an LED on and off using HAL_Delay(1000); function. I copied the same code across to my new project board, uploaded it successfully, toggled the LED on successfully but when I step...
