Posted on February 09, 2015 at 16:34 Hi at all,I would try to program a custom made board with STM32f205RCT7 micro onboard via SWD .I got an SWD connector with vdd,gnd,swdio,swclk,nrst.No pull up or pull down on swdio pin , 10k ohm pull up on nrst a...
Posted on February 09, 2015 at 15:06Hello to all, I use a TIM8 of a STM32F2xx to generate a quadrature signal. This works fine no problem with toggling mode. I send a sequence of pulses out of the OC-Outputs. (a speed ramp). When the sequence is ove...
Posted on February 06, 2015 at 17:29Can someone explain why the following code causes CCR1, CCR2 and CCR3 to have the same value: TIM1->CCR1=value1; TIM1->CCR2=value2; TIM1->CCR3=value3; While the following code doesn't cause this problem (CCR1 and ...
Posted on February 09, 2015 at 04:49Dear all sir: I'm working on STM32_USB-HOST-Device-LibV2.1.0 USB_Device_Examples VCP. This demo code try to send & receive serial data from PC through USB cable and transfer to serial port. Now the I down load th...
Posted on November 25, 2014 at 23:48Hi everybody, these days I'm starting a project based on STM32F103RE uC for which I have to use the CAN bus pheripheral to transmit and receive messages.I have no previous experience with CAN pheripheral on STM32 ...
Posted on February 09, 2015 at 04:16 Hi all, I was able to use the code below to init the SPI and read the values fromaccelerometer SPI_InitTypeDef SPI_InitTypeDefStruct; GPIO_InitTypeDef GPIO_InitTypeDefStruct; RCC_APB2PeriphClockCmd(...
Posted on February 09, 2015 at 20:32Hi All,I have a timer running on my STM32F0 and I would like to change the period of the timer mid-application. Do I need to rerun my timer configuration with the new timer period or can I simply update the single...

Posted on February 09, 2015 at 18:27Hi All,For my application I need to send 5 bytes over UART repeatedly. I store the 5 bytes in an array (TxBuffer) and iterate through it (index 0-4) on every USART_IT_TXE interrupt. When my counter reaches 5, I di...
Posted on February 09, 2015 at 15:13Hello, is there a way to detect connection of some signal to pin (recognize if pin is connected to some signal or if pin is unconnected).
