Posted on February 09, 2015 at 17:59Hello,I have to realize receive DMA timeout for a serial interface. I found the application note AN3109 which describes a mechanism to realize a DMA timeout for the STM32F10x microcontroller. Does this application...
Posted on February 09, 2015 at 15:51What is the usual procedure for power-on reset for other chips besides the MCU? Is there a reset_out signal or method coming from the MCU that is recommended? Or is there a method for resetting all chips in a syst...
Posted on June 03, 2014 at 09:43Hi,I am trying to debug some very simple code for STM32F0Discovery using Eclipse, ARM arm-none-eabi-gdb compiler and OpenOCD debuger.I could build and debug my cods and now I am trying to use printf to see some variab...
Posted on February 10, 2015 at 10:50Hi I am using STM32F103RBT6 @72MHZ I use SPI with DMA to stream data from memory to GPIO SPI Prescaler is 4 GPIO is configured as output push-pull and speed 50MHz The problem is that the data output rise and fal...
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(...
