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...
Posted on January 28, 2014 at 20:18 Hi, I'm using a STM32F407VGT mcu. Also with the latest DSP lib pack from ST. The network has 2 nodes, and I'm attempting to capture the traffic between the nodes. 500kbps 75% SP. 30% bus...
Posted on February 05, 2014 at 16:08Hi Support, As to date, I have successfully implement smart card TX and RX together with DMA. But I encounter a problem. It is regarding on guard time. As per Reference Manual, the guard time can be configured, bu...
Posted on November 18, 2013 at 18:22I am a beginner with STM32F4 and I am study the ETH driver procedure but I don't understand some instructions For example: /* Clear MBC bits in the selected MAC address high register */ (*(__IO uint32_t *) (E...
Posted on February 05, 2014 at 13:44I have an array of data being played out of a DAC using DMA transfer, with the trigger provided by a timer (TIM6). This works fine, but I would like to occasionally change the data at run time. To do this I have c...
Posted on February 05, 2014 at 13:41Hi,Kit using : STM32Discovery Board(STM32F100 controller)I have implemented the input capture mechanism for Timer15 channel 1. In which I set triggering for both falling and rising edge.Now I am trying to port the...
Posted on February 04, 2014 at 22:23Hello, I have problem with software implementation of SVPWM Space Vector PWM modulation for STM32F1 microcontroler. My application is scalar V/F converter for 3 phase asynchronous motor. Does anyone have such read...
Posted on February 04, 2014 at 13:38I had connected 0.1uF to reset pin which was creating problem while debugging with ulink2 on keil. This was given in datasheet.But on removing this capacitor from reset pin , debugger works fine & running. But whe...
