Posted on June 28, 2016 at 10:05Hi! I have a problem with SD card I write a file every second (30 byte added at the end of file) (SDcard @ 4MHz clock 4 wire) and sometimes, when firmware enters in HAL_SD_ReadBlocks function, it blocks at this stag...
Posted on June 28, 2016 at 17:14Hallo, Leider komme ich noch nicht so ganz mit dem lesen von I2C Slaves klar. Das schreiben klappt. Hat jemand eine funktionierende Routine womit ich das lesen mal testen könnte? Im Internet finde ich zwar vieles, nic...
Posted on June 27, 2016 at 12:22 Hello, I'm trying to get temperature from internal sensor of the STM32F7 I'm a begineer and I'm working on a discovery kit directly on mbed. Currently, the functionHAL_ADC_PollForConversion return no...
Posted on June 25, 2016 at 00:20I'm using 4.14 (although I had the same behavior with the most recent build on a different machine) under OS XWhen configuring the USB devices on an stm32f303VEx, the pins are not correctly configured -- indeed there...

Posted on June 21, 2016 at 22:28Hello, I have used a timer for triggering ADC for sampling per 20uS and use DMA to transfer 100 sample to the array. I suppose that the total time of converting and sampling time for ADC is about 2uS. So at each 20uS...
Posted on June 21, 2016 at 14:56Hello!There MK STM32F0. It works at a frequency of 48 MHz. Background program is an empty infinite loop. In front of the signal on the output MCU configured external interrupt. The interrupt handler only operation wit...
Posted on June 27, 2016 at 19:58 I have and EXTI fire when the signal goes high and I want to check the signal 15 microseconds after the interrupt. I'm using a TIM but it doesn't work. I'm using an STM32F4 Discovery MCU #include ''stm...
