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! Switching time for mux on Opamp

Various STM32 products have opamps that have a mux in front of it.Ex: STM32G4, STM32F3, STM32H7 series, etc.If I change the mux input setting using the control status register (OPAMPx_CSR::VP_SEL or VN_SEL), how long does it take for the mux to switc...

FMC peripheral memory

How far from FMC shall we place memory device. I have stack-up design(3 boards) in which MCU is on top board and FPGA is on bottom board. I need to map FPGA to FMC. Are there design consideration for routing FMC signals for such board to board commun...

ADC sampling time measurement

I have a reading problem with dmaWhen reading multi channel with ADC dma I need to know when to sample each channel. In the ADC input, I found a 2us transient in the oscilloscope output below. I considered this transient as adc sampling time and adju...

HAL SMBUS on STM32L071xxx, how to set up correctly

I configured I2C SMBUS in cubemx and reimplement HAL_SMBUS_MasterTxCpltCallback, then I called MX_I2C1_SMBUS_Init() and HAL_SMBUS_Master_Transmit_IT(). After that i had no any events: not called callback and no any data transmited. In fact on sda and...

I am trying to setup DMA with ADC on stm32h747 even thoug conversion end DMA transfer never completes. The ADC's conversions are triggered by a timer (this part of the code works fine) and the DMA is supposed to write the data to memory.

Here is how I setup my DMA ; Enable Clock for DMA1Periph to memoryset memory and periph size to half wordset memory address increment and clear periph address incrementset circular modegive the flow control to the ADCSet DMAMUXSet DMA periph addressE...
