Posted on August 12, 2011 at 19:06Hello.I have a problem with starting OTG FS in Device mode. I will try to adapt project example ''STM32_USB-FS-Device_Lib_V3.3.0'' for this STM32F-2 chip, but USB doesn't run. For new chip I'll do next: 1. Prepare s...
Posted on August 12, 2011 at 15:05I have no clock on PC12. But when PC12 is OUT mode it is work. If I run mySDInit() I will see two jump on pc12 ( out mode test ). No clock. Where is the bug?void mySDInit( void ){ uint32_t regSDIO_CLKCR; GPIO_In...
Posted on August 15, 2011 at 13:50Hello I would like to switch from the HSE oscilator to the HSI oscilator if there is a failure of the HSE oscilator. How can I do that with preserved SYSCLK (64MHz)? The HSI klock is divided på 2 så the PLL would ...
Posted on August 09, 2011 at 08:41Hello, Since the beginning of the project on the STM32F205RG, I had hard faults from time to time. These last days, I wrote a hard fault handler as described in Joseph Yiu's book to see why ... and the result was ve...

Posted on August 06, 2011 at 00:00I'm using the STM32F103RCT6. I need two PWM outputs, where the period and polarity of each is the same, but one output is 180� out of phase from the other. A duty cycle change must affect both concurrently. The c...
Posted on August 12, 2011 at 12:18Hello,I'm trying to figure out the production process of my product and I cannot understand how the SYSCFG_MEMRMP bits work.Is it possible (and how) to put the boot pins physically (via pu/pd res) to boot the builti...

Posted on August 12, 2011 at 12:19Hello everybody. I would like to ask about measurement of Vrefint using ADC1 in STM32F106 64 pin. After conversion I get 0x18E. How to convert this value in voltage? #adc1-stm32
Posted on August 02, 2011 at 15:52I use DMA to write a string to USART2. After power up I trigger transmittion by pressing down a switch and detect ( oscilloscope ) that the usart transmitted two bytes less than expected - after that every time I t...
