Posted on March 16, 2015 at 08:12I use UART + DMA to receive unknown length packet, and use IDLE interrupt to monitor the end of the packet. It can recevie IDLE interrupt, but in HAL_UART_IRQHandler I read SR register and IDLE flag is 0. I never en...

Posted on March 13, 2015 at 01:51Hi, we're using stm32f103c8t6 to generate various PWM signals to various components on the PCB. TIM1,3,4 are used to generate different PWMs and TIM2 is used as a 1ms timer. Recently we've realized that we will need ...
Posted on March 15, 2015 at 04:33hi guy. I have a problem with accelerometter- gyroscope: how to set address for accelerometter by I2C I need code communication with gyroscope A3G4250D thanhk you very much!
Posted on March 14, 2015 at 20:24Hello everybody. I try configure the timer 3 with external clock, but I have a problem. When done a signal in PD2 (ETR), the timer don't increase. I think that problem is for any enable clock... I use HAL libraries w...
Posted on March 14, 2015 at 11:40Hi, I'm measuring the pulse width on one line, using TIM2. Everthing is fine if I use Ch2 (on PD4 or PB3) but I can't get a reading using Ch3 (on PD7). I'm using : TIM_GetCapture1(TIM2) Here is the init code, thanks ...
Posted on March 11, 2015 at 18:12I am running STM32F407 with IAR EW toolset and trying to put the CPU into sleep mode.The processor never stops at __WFE( ).Any idea what I am doing wrong?
Posted on March 14, 2015 at 02:59i require to open multiple files simultaneously and, read and write multiple files using stm32f4 and fatFs , as a test i used f_open with 4 different file names and file pointers but only two files got created in car...
Posted on March 12, 2015 at 09:36Hi,in my application, I need to make signal filtering using digital filters.I take ARM's DSP library and fir example, but it is not so useful for me, because there are samples stored in memory already and they are us...
Posted on March 13, 2015 at 19:06Hello all, I faced problems with SPI2. First I interfaced a graphic LCD on SPI bus and could not get to working properly, though it works well on an Atmel 8 bit controller. Spent more than 3 weeks without much luck. ...
