Posted on February 06, 2014 at 14:06 Hi, I need help with my Stm32F4 In this example I want to clock Tim4 with Tim2 using the slave mode. This is working fine! But when I want to use Tim4 to rise an update-interrupt this line stops the MCU. So...
Posted on February 05, 2014 at 18:41Hi All!I would like to use the STM32L152 Opamp output pin to pulse drive the MOC3020 optotriac.The pulse current should be ca 15mA-20mA for the optotriac to fire up under any temp. conditions.Can I source this a...
Posted on February 06, 2014 at 09:26Hello together, i´ve been searching for information about the minimal voltage wich has to applied to Vref-. In particularly it is around the stm32f103CBT6. I´ve used the search function in the RefManual, but co...
Posted on May 22, 2012 at 15:25Hello, I try to work with the UART4 RXNE interrupt but something went wrong. // USART2-TX, UART4-TX GPIO_StructInit(&GPIO_InitStructure); GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure...
Posted on February 05, 2014 at 23:54 I have just implementet a Low Speed Internal (LSI) oscillator calibration using a timer connected to the High Speed External (HSI) crystal. Right after I enabled the timer interrupt (and probably interrupt fi...
Posted on January 31, 2014 at 01:19Guys, Where can I find the library for :STM32-MP3NL/DEC Audio Engine MP3 Decoder and Utilities http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/PF250969 Thanks
Posted on February 04, 2014 at 22:53 Gents (and maybe Ladies), My goal is to wait until a certain amount of data has been received. I have setup an interrupt (Can Bus) and when it is triggered it stuffs the message into an Array. I'm usin...
Posted on January 24, 2014 at 15:45Hello,The USB specification for Full Speed requires 1.5Kohms from D+ to 3.6 volts, 15Kohms from D+ to ground, and 90 ohms between D+ and D-. What matching resistors are required to achieve this with the STM32F103C...
Posted on February 02, 2012 at 07:27 i am trying to work with quadrature encoder (TIM8, pins pc6,pc7). here is my code: /* Enable GPIO clock */ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC,ENABLE); RCC_APB2PeriphClockCmd(RCC_APB2Pe...
Posted on February 05, 2014 at 13:41 Hello, I'm currently getting ADC values and storing them into an array, incrementing the array after storing each value. I want to make the array quite large, but the program crashes if i go above arr...
