Posted on October 28, 2013 at 15:22Hi All, I am working on USART1 device for STM32F429I_DISCO board. [I have already tested my serial device (code) on stm32429i_eval1 board.] I am using following USART setup/pin mapping unsigned int temp; /* Enab...
Posted on November 05, 2013 at 17:21Recently I had a chance to do some quick ESD tests on my board, unfortunately time was very limited. Some basic information: -STM32F103T8U6 MCU, -USB bus powered, -USB is already protected with USBLC6-2SC6, -Plas...
Posted on November 07, 2013 at 15:44Hello all,Recently I came across a puzzling situation. I have a system that behaves differently depending on whether I am debugging the application or running otherwise. My environment1) STM32F103x running at 8MHz...
Posted on November 08, 2013 at 10:28Good morning,i have a problem with the board STM32F4 - Discovery. I'm using the example ''Audio_playback_and_record'' for this board. I configured this example to read file from a media usb key ( i have uncommente...
Posted on November 05, 2013 at 14:31 Hi all, I am porting code from an existing Intel 8031 platform onto a STM32F4 The software performs PID calculations. The softwqare has been running without issues on the 8031 for several years, but...
Posted on November 07, 2013 at 23:59hello.My question is this: I'm driving a TFT screen (320x240, 8-bit) with SSD1963 controller. the problem is that if I select FSMC_MemoryDataWidth_8b; My screen mestra anything. however if you choose the 16-bit mo...
Posted on November 07, 2013 at 12:14Hello everyone,I'm writing data to SD for a few seconds/minutes. If I disconnect the board while recording, when I look at the file with windows, it shows the file with an extension of 0Kb. How can I fix the file ...
Posted on November 07, 2013 at 18:17I have designed a variable pulse generator using the STM32F4 and using 7 timers which outputs on three pins, using AF pin couplings to TIM1/TIM8/TIM9(all operated in OPM mode) because I wanted the 6ns resolution p...
Posted on November 06, 2013 at 23:06Hi, Last time, I programed multi channel ADC with channel0 of DMA2_stream0. And now I try to add one more channel for USART with DMA2_stream0. I know each DMA stream has maximum 8 channel and they share DMA_SxCR...
Posted on November 06, 2013 at 22:39Hi Everyone,I have just finished a project with the MCU STM32F427II but I can not program it. I use the ST-LINK v2 programmer with a 4 wire (SWD).I have check all the connection and I found that the pin (bypass_re...
