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...
Posted on June 11, 2013 at 13:02Hi,I'm trying to use FLD v2.6.0 with STM32F407ZG rev Z. No problem to connect, uploading an image written by SWD works most of the time, erasing and downloading gives mixed error messages such as for example that eras...
