Posted on June 07, 2014 at 16:52 hello dear forum I designed an inverter for vibration tank ( photo below ) it issimply an H bridge with 500 V 20 A mosfets the frequency and duty is variable with STM32F103 the vibrator worked...
Posted on June 10, 2014 at 15:42Hello, as described in the reference manual, the STM32F103 have timers with up to four channels - for example TIM1 - TIM5. But in my application i need only one channel (for output compare or pwm output). In the Micro...
Posted on January 14, 2014 at 09:16Hello,I can't get SPI3 on pins (PB3, PB4. PB5) working. On the scope I checked that SPI clock is running. But still I can't read MX25L6406E flash ID. Functions that handles flash commands are checked and is working...

Posted on June 10, 2014 at 10:14Hi, I'm porting code from a M0 to an M3 part and libraries are quire a bit different. I need a quick tutorial on initializing the RTC and setting time and date using the stm32f103 part. I've already obtained the date...
Posted on June 09, 2014 at 17:26Hello all, I am working with an STM32L1 and a I2C interface (Concretely I2C2, Pins PB10 and PB11). I tried different things but I am still not able to overcome the following issue: after intialising the I2C interface...
Posted on June 09, 2014 at 06:07I am updating the tim2 arr by DMA ...with the update of timer 2 DAC will get triggered. I have checked the DAC o/p with CRO by it's corresponding pin and I am able to see the Sine wave but the problem is it is not en...
Posted on June 10, 2014 at 10:57I try to develop my own proprietary bootloader for STM32407 that work over UART and Ethernet. Is there any source code example?
Posted on June 10, 2014 at 11:46 Hi Guys, I've a bit of an understanding problem of the DMA in a STM32F103 µC. I'm trying to set the base address to a pointer (not to an address of a static varialbe). My problem is, that if I set the p...
Posted on June 09, 2014 at 12:53Hi, I can't stand why my stm32f4 does not do the floating point calculation.Frequency = (RCC_Clocks.HCLK_Frequency)/2 / (IC2Value * (TIM4->PSC+1));Frequency is a float variable, but when i read it with ''printf'' ther...
