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.

For STM32F7x 14pin JTAG on target board and compatibility with ST-LINK/V2

Hi,On my target board I have implemented 14 pin JTAG interface as in STDC14 CN1 connector. Can I use ST-LINK/V2 debugger to flash and debug the controller..?The controller part is STM32F750V8. Please help with this.Thanks,Dhara

Question about access internal flash on STM32H7

My codes are stored on bank2 and I am trying write some manufature data into BANK2 (sector 14) of internal flash.Howerver it always fail in erase stage dut to the flag of PGSERR is raised.If I change to write data to bank1 (sector7) this symptom not ...
