Posted on January 05, 2014 at 19:36Hello, the STM32F105 Device share USART1-TX and VBUS for USB on Port PA9. I need the USART1 for communication and for the internal Bootloader (only USART1 on my used 64pin Devices possible), if the firmware corrupt...
Posted on January 08, 2014 at 16:06HiI'm working on a project where I use a interrupt from the RTC. This is the one second interrupt. I also use a couple of other interrupts, for example timer 3. The RTC interrup can have the lowest interrupt possib...
Posted on January 10, 2014 at 06:05Hello all, hopefully someone can see the error of my ways? I have a some hardware with a couple of rf modules IO lines connected to Port D pins 10, 11, 12, 13. All is well except for pin 13 which is always providin...
Posted on January 09, 2014 at 20:19Is there some way I can programmatically turn off the LCD Backlight on the STM32F429i-Discovery when I don't need it?Tx
Posted on January 08, 2014 at 21:05I have a legacy system that uses a STM32F103RE device and I would like to connect to it via JTAG (or any other on board option) and view the code on the device to verify it's version (and possibly update). It seem...
Posted on January 09, 2014 at 17:19I have setup the USART to Tx/Rx however my application requires sending a Break. The STM32F programmer's manual refernces sending Idle and Break, provides an example and register for sending an idle character but n...
Posted on October 25, 2013 at 16:13Hi, I am using olimex kit of STM32F103RBT6 microcontroller. I am new in USB virtual COM programming. I am using STM32_USB-FS-Device_Lib_V3.3.0 with Keil MDK-ARM 5.0 IDE. I opened the precompiled Virtual Com port p...
Posted on January 07, 2014 at 23:00Using an STM32F407xx, I want to monitor Vdd by connecting it to Vbat and using ADC1_IN18. If I am not actually powering my device from the battery, is it still possible (or advisable) to do this?The reason that I a...
Posted on January 09, 2014 at 13:14In order to test the Hard Fault interrupt, I modified the Systick example on ''STM32F0xx_Discovery_FW_V1.0.0'' as follows.. on main.c I added two lines: ------------------------------ int main(void) { uint8_t* Byte...
Posted on January 08, 2014 at 08:35Guys, How to calculate date,month and year ? from RTC_GetCounter function, I saw : uint32_t RTC_GetCounter(void) { uint16_t tmp = 0; tmp = RTC->CNTL; return (((uint32_t)RTC->CNTH << 16 ) | tmp) ; } I've done ...
