I am currently working with the MCU STM32F407ZET6 used in an embedded device. I am relatively new to this MCU, but I'd like to know if there is a persistent register that I can write some 32-bit value to it and it does not get erased if the MCU is tu...
Hi. I must use PTP and also precisely capture 1PPS input as a backup/alternative sync source.In the manual DocID029587 Rev 3, page 2705, there is a secion "Auxiliary snapshots with external events" in which ptp_aux_ts_trig_i is mentioned. But I can't...
I've implemented USB Host Suspend/Resume function. It work fine. I set USB_OTG_HPRT_PSUSP, when I want resume I set USB_OTG_HPRT_PRES and reset this bit after 20 ms, I see with an oscilloscope, the D+ and D- signals, in suspend state D+ is high and D...
Hello, Everyone!I found issue with using my LCD (via i8080 mode) with FMC. My display requires HOLD after DATA set from 15 ns time. But in all FMC modes HOLD fixed and it 1 FMC CLK. For my STM32H743 at 400 MHz - I set FMC clock 200 MHz. It is HOLD = ...
Either I checked the wrong datasheets, use the wrong keywords, am blind or the answer is in a source I didn't find or check.Please help
Posted on November 09, 2012 at 14:35Hello, I want to use a Everspin MRAM MR256A08BCMA35 with the STM32F407IG. This memory needs a stable address after write or chip enable goes high for at least 12 ns. My STM and the FSMC are running with a HCLK of ...
Posted on October 10, 2014 at 17:16Hello,I am making a device that uses the TVP5150 via DCMI to display a video using YCbCr on an STM32F429I devicein 4:2:2 format. It is clear in the Reference Manual that the STM32F4 supports YCbCr in DCMI, but it i...
I am trying to implement SPI protocol using peripheral CRC in STM32F7 nucleo board. In that I have used 8-bit CRC with polynomial = 07.Even if we are sending incorrect CRC to controller(which is act as a slave), then it’s not enabling CRCERR flag.Can...
i'm using a stm32f429 and i would like to now is it possible to turn the screen from vertical to horizontal.
when we debug and compile in ST-Link/V2 by IAR IDE in STSPIN32f0 then this shows a problen that fatal error no MCU find. so what should be do for remove this error
