Posted on March 01, 2014 at 11:52Hi, I want to generate a timer interrupt for 6.25 us, 9.375 us, 0.1 milisec, 0.4 millisecond and so on . I think that it can be done by using DMA taking the array SRC_Buffer_DEC[4] ={200,300,3200,12800} as DMA memory...
Posted on April 06, 2014 at 14:25Hi all,I just started developing with the STM32F4 Discovery board and I've been trying to use STM32CubeMX for code generation.Until now, almost every configuration I tested didn't work, that means STM32CubeMX (I'll c...
Posted on June 06, 2014 at 16:02i know about usart, for transmited by transmittter and received data by receiver i can do it.. i communication usart use looping and use array too... how can i make this array to become string so i can use function l...
Posted on June 06, 2014 at 13:14Hi all, Presently i am capturing input signal only on its rising edge and also i can capture the same signal only on its falling edge. But i need to capture on both rising and falling edges, please let me kn...
Posted on June 07, 2014 at 00:56Hi ST,I'm using ST32F4Discovery board, and I want to read a 4 bit data that is continuously streaming in. I'm thinking of doing:1. set GPIO port for the input (say PA10)2. call this function to read data: GPIO_ReadInp...
Posted on June 07, 2014 at 00:06I have to transfer 1000 integer elements stored in an array. How do i transfer over UART using DMA.Please let me know, its urgentRegardsSameer #dma
Posted on May 14, 2014 at 10:18Hi I have an STM32F4 board. When I connect a jumper to f14 and start up with a USB cable connected, the device manager of the connected PC sees a DFU Device connected and I can perform a flash upgrade over USB. When I ...
Posted on June 06, 2014 at 02:06Hey ST,I'm using STM32F4DISCOVERY board, and tried to write a counter for rising and falling edges using timer input capture mode. Couldn't capture anything though. Any ideas what's wrong would be appreciated.Also, do...
Posted on June 06, 2014 at 11:00HiThe bootloader GO command doesn�t work as expected. Generally AN3155 is wrong here, because the second ACK after the address isn�t send also on other chips (STM32F2, STM32F4, �), but the jump works there.Test system...
Posted on June 05, 2014 at 16:16Hi,I am currently working on an application that will send/receive time and date data through serial connection via UART. To get a prototype up and running, I modified the RTC calendar example code that comes with STM...
