Posted on December 24, 2015 at 18:32Hi, I'm getting started with the 'F401 device, I'm trying to blink the LED on the Nucleo-F401RE board when Timer2 triggers. I know this is just register level stuff and I'm probably making things harder for myself...
Posted on January 03, 2016 at 07:39Hi fellas I have soldered my MCU (it's STM32F103RBT) on the board and I also can program/erase it. I even have control on it over debug(SWD) then I think everything is okay but it doesn't work. this is RCC's regist...
Posted on December 29, 2015 at 16:00Hi all,I've downloaded the following simple code in my STM32F3DISCOVERY but I don't see anything. Should be a sistem clock config problem?In main.c:&sharpinclude ''stm32f30x.h'' /**********************************...
Posted on December 31, 2015 at 00:37Hello, I am currently developing a Visual C++ program that interacts with an STM32 via the STVP programming toolkit. Once this program is complete I plan to wrap it in an InstallShield installer. The documentation...
Posted on January 04, 2016 at 10:58I am using a STM32L152RE Nucleo Board and programming with EmBitz using the Standard Peripheral Library.I am trying to generate a ramp signal using DAC channel 1 and DMA Channel 2 using Timer2 as trigger. The code ...
Posted on January 02, 2016 at 23:18Hi.What is the main reason to use one watchdog instead of the other? I understand that IWDG is clocked by its own LSI clock, while WWDG clock is prescaled from the APB1 clock. But what are the other differences?
Posted on January 03, 2016 at 23:37Hello all,While using USB as a mass storage (STM32L MSC, FS_Device_Lib_4.0), can MCU read PC system time and update RTC date/time accordingly?Any idea how to do that or any sample code? USB MSC configuration for ST...
Posted on January 03, 2016 at 21:20I want to output the max 48MHz clock signal on STM32F030 to drive another subcircuit. The problem is the chip STM32030F4P6 (TSSOP-20 package) I prefer to use doesn't have the MCO pin (PA8). So I have 2 questions: 1...
Posted on May 12, 2014 at 09:29Dear all, i am using STM32F405 with internal osc. clock. I connected a 3V lithium battery as VBAT, and would like to use the RTC to keep time when power is off. I read some samples here and there and implemented some R...
Posted on June 10, 2015 at 23:34Hi,We want to add a cell battery to keep time and date. but in the schemaitcs, Pin 1 and Pin 6 in STM32F429iDisco for VBAT alredy connect to +3V.What we can do?Thanks a lot
