Posted on February 22, 2014 at 17:03I have a problem with serial-over-USB port reconnection after stm32f4discovery board reset (for instance, re-programming) - with the native USB controller port, not the uart dongles. I have originally reported thi...
Posted on August 25, 2016 at 14:29Hi all,I'm still relatively new to development on MCU. So I'm hoping to get some help to start.I need to measure time between pulses in 20 nanoseconds resolution or less. I then need to transfer the measured value t...
Posted on August 30, 2016 at 03:56Hi, I am using pin PA4 as a DAC output on an STM32F405. I then have a unity gain op-amp buffer. My supply is 3.3V. What I want to do is rather than create a SINE output at some frequency, is to generate a DC signal....
Posted on August 31, 2016 at 23:19Hi,I am trying, using an STM32F103 to add CDC/VCP support. Results have been been widely variable PC to PC. But the one de facto result is that 32bit Win OSes are rock solid stable, but 64bit Win OSes show up a plet...
Posted on August 29, 2016 at 12:22Hi, I have bought me a Nucleo-L152RE board to test the STM32L152 MCU. Now I want to write data to a uSD card using the FatFs file system. Since this STM32 MCU doesn't have a SDIO bus, I want to use SPI. Does anyone ...

Posted on February 27, 2016 at 10:53 Hello I am using STM32F030CC to communicate with BQ3060 fuel gauge through SMBus. Everything is working kinda fine, but I am little worried about my repeated start condition. I know reading 2 bytes ...
Posted on August 04, 2016 at 12:07 Dear, I want to generate the 4 signals for a H bridge to create a sinusoidal signal by pwm So I used Timer 1 and its 4 channels powered by a DMA in burst mode The PWM data are organized in an array of 360 structu...
Posted on July 17, 2015 at 16:18Hi,I am having problems to run the WWDG in a STM32F405.I am using the HAL Drivers from Cube MX.The process is the following:{__HAL_RCC_WWDG_CLK_ENABLE();MX_WWDG_Init();HAL_WWDG_Start(&hwwdg);HAL_WWDG_Refresh(&hwwdg,12...
Posted on August 02, 2016 at 10:58Hello,I use a nucleo stm32f401RC Evaluation Board for the regulation of a boost converter and I need to generate the interruption on the ON half-signal of PWM and I need also synchronize the conversion of 3 channel ...
