I have seen examples for STM32F4 series, where they write asFALSH_ERASE(SECTOR 11,); and FLASH_PROGRAM_HALFWORD(XXX,XXX,XXX);FLASH_Unlock();How to program for flash memory in STM32F103C8T6 ??Please help if anybody knows answer for this.Your help will...
Hi Everyone!I have read a lot of topics, articles about the F070 ADC settings, calibration, etc., but I couldn't solve my issue. I'm using ADC with DMA right now, but the problem is the same with the interrupt and the polling method. In my code I'm u...
Hi ST team, Any solution currently available from your side . This issue causing trouble for the project using ST controller. we selected ST because of availability of peripheral stacks. Please update as early as possible
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...
