Posted on October 31, 2013 at 09:23 Hi All, a couple of questions about the RTC Alarm. I have got the RTC Alarm working (using LSI), and raising an interrupt (RTC_IRQHandler()) successfully, but I'm stuck on the following:- 1) I would li...
Posted on November 07, 2013 at 15:34Hello, I want to establish a simple point to point RF communication using STM32w108CB microcontroller. I used the STM32w RF control kit to understand how to use the RF feature. I find the simpleMAC library file fo...
Posted on November 12, 2013 at 23:59Hi all, i'm using STM32F417 at 168MHz, and i would like to synchronize ''while'' cycle with totally 4 instructions with 6 time cycles (for example: ldr ldr tst bne) with 28MHz signal on PF8, so i configured EXTI w...
Posted on November 11, 2013 at 10:33Hello, I am working with STM32F4 Discovery with FreeRTOS and summon arm tool chain.I am sending ADC data over serial Port using USB serial communication.I have write code to get ADC value in continuous conversion...
Posted on November 12, 2013 at 04:01 HELP!!!! I've been banging my head against my keyboard and I can't find what's wrong with this code: /********************************************************* **** INITIALIZE TIMER AND PWM ...
Posted on November 12, 2013 at 22:41Hi All, please somebody help me to write this c code into asm: void EXTI9_5_IRQHandler(void) { /* Clear the EXTI line pending bit */ //EXTI_ClearITPendingBit( EXTI_Line8 ); EXTI->PR = EXTI_Line8; NVIC->I...
Posted on October 03, 2013 at 04:13Hi, I'd kindly ask if anyone can point me to robust uart example, possibly with interrupts, dma and hardware flow control... I also wonder how flow control affects other code and functions ? Thanks in advance, rega...
Posted on July 05, 2013 at 15:12Hi,I didnt find nothing in the datasheet refering the data update rate of the calculations that STPM01 do. Do any one knows? I gues that it is 16,66ms but I am no sure.Bye
Posted on November 11, 2013 at 14:18I have just ported one of my systems over to the STM32F4Discovery board. It is a small OS + TCP/IP. However, I stumbled on a few things: I need to have a 8 khz interrupt for audio sampling. I think I have clocks O...
Posted on October 03, 2013 at 21:20Hi Folks We are porting a complex algorithm from the PC into the STM32F407 and we are testing it on a large test file (15000 items long) which I have include in a .h file in the form const int testdataA[15000] = { ...
