Posted on February 27, 2017 at 09:40Hi, I've got two STM32F410 communicating over I2C using HAL FMPI2C library (v 1.14.0). Both initially enables FMPI2C listen with interrupt.When one of the STMs wants to send data, it: - disables FMPI2C interrup...
Posted on February 26, 2017 at 13:06hi everybody I want to do the project on and off for LEDs with dma and timer Without engaging the CPU's but i cant some body help meor give me sample from this
Posted on February 27, 2017 at 14:07Hi all, i am using GPS module in the project interfaced to the stm32f0 MCU. Everything working fine but how to send the float values of long&latt on the uart .i tires replies in community but no luck. is there any...
Posted on January 25, 2017 at 08:56Hi,I'm working on a STM32F101T6U6ATR, and need to 'talk' with it via i2c (PB6, PB7).There's an errata (STM32F10xx4 STM32F10xx6 Errata sheet, en.CD00211391.pdf) talking about lot's of i2c issues.I've created a proje...
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 ...
