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...

Resolved! STRM32F303 EXTI9_5 and EXTI15_10 external interrupt triggered either on falling or rising edge although programmed to be triggered only on rising edge, how to fix this?

Hello,So we are building a ball shooting robot which self detects the speed the ball was launched. The average speed is in range of 80mph. To get speed we are using two light gates, one on PF9 and one on PF10. So I set up EXTI interrupts on these two...

Resolved! Interrupt priority in STM32F1

Hello,My question is that how many interrupts could be in pending state in STM32F1 MCUs? What would happen when a interrupt is running and in the same time another interrupt with same preempt priority be fired, does the running interrupt finishes and...

Reading of ADC jumps randomly by about -20 counts

I am currently using an STM32L475VCT in my board design, and I also have an STM32L476G-EVAL board.I have ADC1 set up for sampling 6 channels continuously. Each conversion is triggered by an output from timer 1, I am also using 4x oversampling. The ti...

I2C bridge

Dear all,In my system, STM32L412 is between MCU_B and Dev_S. The role of the STM32L412 is a bit like I2C bridge.That means MCU_B does any I2C read/write command from/to Dev_S must by the help of STM32L412.It is simple for STM32L412 receives I2C write...

Resolved! Why would an ADC sample in 8-bit mode when DMA is used, but when used without DMA the full 12-bit conversion is retrieved. - STM32F411

I am trying to set up an example project for ADC with DMA using HAL library. I am sampling a slow ramp function from 0-3.3V over 2500ms.For conventional ADC setup:When debugging the code I can see that the retrieved ADC value the full 12 bits.For ADC...
