The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello everybody,I read everything I found, and it's still not clear.First, I've got my OTG_FS_Core in OTG mode with ID line.I don't need High Speed USB.Q1: Is there 2 dedicated FS Phy, (one for each Core, FS and HS)?Q2: How can I get the OTG_HS_Core ...
I attached a battery to my STM32, and my RTC is now keeping the time when the board is not powered.But when not powered, the clock is also not advancing, which means that when I power on the board, the RTC shoes the time when I powered off the board....
I've an STM32F103C8T6 CPU, but I can't find appropriate linker file. The closes file is `STM32F101XB_FLASH.ld`. Can I use it with change following line (#43):FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 128KtoFLASH (rx) : ORIGIN = 0x08000000,...
I'm trying to convert 3 ADC channels using DMA. But the variables don't seem to change when I watch them in the debugger. I know the conversion complete callback is executed because I breakpointed it. So this suggests that the DMA transfer is not exe...
Posted on April 13, 2018 at 01:38I have built a custom STM32F446ZE board and I used the ST890CDR current protector and the LD39050PU33R voltage regulator in exactly the same way they are implemented in the Nucleo Board from ST. The only difference i...
Hi, I'm using 2 STM32F7-SOMs and the same program for both of them. I have ran my program on the original STM32F7-SOM, and the USB host was working. Then, I ran it on the other STM32F7-SOM, and the USB stucks at enumeration state. Any suggestions or...
I have been able to implement individually:SD + FreeRTOS + FATFS + DMAUSB + FreeRTOS + FATFSI want to know how can I make (SD + USB + FreeRTOS + FATFS + DMA) work. Example would be great. Thank you every much.

I cant't figure this out. I had no problems installing and using the driver with a Nucleo board on my desktop. However, the installer keeps failing on my laptop. The installer asks for and I give it admin privileges. I tried to manually update the...
I can't get the STM32L07RZ-Nucleo ADC regular conversion interrupt example to work. I'm using the Keil MDK variant. I upload the program, start the debugger and put uwADCxConvertedValue into watch window #1The doc file says to connect a signal to P...
