Posted on February 27, 2017 at 16:53Hello,rm0401 rev.2., rm0402, rev4 and rm0430 rev.2 all define the FLASH_OPTCR reset value as '0FFFFFED'. This would imply read protection on all sectors and is obvious wrong.Please correct, if not already done!
Posted on February 27, 2017 at 12:01Hello,when running code in RAM, the manuals tells'To get the max performance on SRAM execution, physical remapshould be selected (boot or software selection).'That way code from RAM can be fetch I-Code interface.D...
Posted on September 08, 2014 at 11:08 Hello there, I am using IS61WV102416BLL external SRAM module. I got it working with a STM32F4 microcontroller. The problem now is that every time I write some data to the SRAM it is copied to an addr...
Posted on February 24, 2017 at 17:51hey,I tried to run usb hs + vcp with code created by CubeMX.In generated code i have changed:#define APP_RX_DATA_SIZE 64#define APP_TX_DATA_SIZE 64and included in main.c:#include 'usbd_cdc_if.h'also changed:Stack_...
Posted on February 27, 2017 at 11:40Hello,rm 431/385/410 for the STM32F7 series in chapter3.4.2 Programming user option bytesdoes not mention how to programm FLASH_OPTCR1.For the STM32F46 series RM0386 shows how to program FLASH_OPTCR1. Probably STM...
Posted on February 22, 2017 at 09:58Hello, These days I was working on the internal RTC of STM32F070, I looked at the examples majority are those in which STM32 micro controller possesses VBAT pin as opposed to my STM32F070 doesn't have that pin, I ...
Posted on February 27, 2017 at 06:38I have a problem.the problem is please install truestudio toolchain to open the project or associate the file type of the project with your toolchain in system default program settings.i don't know how can i solve...
Posted on February 27, 2017 at 07:07Since the Wish List seems to be closed, I'll put this request here.To the processor designers:The DMA transfer count is a 16 bit value that can be in the range 1-65535. Since 0 is a useless value and 65536 would b...
Posted on February 27, 2017 at 04:34GreetingsI'm trying to determine how I set the DC conditions (i.e. input bias) on the +ve input of an opamp on the STM32F3 series when all the feedback is internal during PGA mode. If I set the input to half way b...
Posted on February 26, 2017 at 20:30Hello all,i need to measure an external clock source of 32768hz with little variation as posible... this means to measure as true as possible, with variations maximum of +/- 2hz ...Is this achievable with inpu...
