HO to put STM32 IoT node into deep sleep and wake up every hour from alarm clock.

HI I am using the STM32L475 IoT discovery kit, I want put my board into deep sleep and wake up every one hour based on event, I was considering setting up alarm clock. I am using x-cube-cld-gen library'r MQTT example. For now i have scene other examp...

iolink support for STM32L452

Dear All,We have our custom board in which we used STM32L452 chip. Now we want to access this board as iolink device.we have one reference code of "STM32L073RZ-Nucleo", so can anyone help us to port example code for our board means STM32L452 chip?Tha...

How much of a frequency drift of the driving clock from the grandmaster source clock will cause the "Incorrect flexible PPS output interval under specific conditions " errata to occur?

Our desire is to use the flexible PPS with fine correction for synchronization purposes. We are wondering if it might be possible to avoid the incorrect flexible PPS output interval with a quality grandmaster. Is it possible to get a clarification of...

Using 2 FMC devices at the same time from different threads

Hello,As I understand FMC bus uses CS when with other device.Does it mean that we can use more than one device at the same time from different threads ?Thank you,Ran

Address mapping of 1GBit of continuous memory (Parallel NOR Flash M29EW) - FSMC/FMC

Hello Folks!So far, I've been able to utilize the FSMC/FMC peripheral in many different scenarios, including interfacing LCDs in 8080 mode, legacy ASICs, SDRAMs, etc. I'm now working on a project that involves M29EW Parallel NOR Flash (1GB single-die...

DFSDM latency

We are using the STM32f413 with the DFSDM unit for converting the PDM stream generated from the external ADC. The clock is generated externally. We are using the OSR of 512 and sinc3 filter with an integration time of 8, a regular channel with contin...

Hi, I am using STM32F103RCT6 in a project. These project make power test fail. More specific, when we power OFF the device and power ON again, if the power ON occurs when voltage is ~1V then the uC is not working.
