Posted on June 27, 2016 at 16:48we try to use a uSDcard efficiently to log process Data. This works great. Now we would like to erase certain sectors in order to have a kind of a ''ring buffer'' for these process Data. We can't find any documentati...

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...

Posted on July 30, 2013 at 10:15Hello, I am new to STM32F4 and I have been digging into documentation for the lasts two weeks.My application uses a 320x240 LCD display and is managed through the FSMC bus. If I have understood correctly the FSMC mana...
Posted on June 27, 2016 at 17:40I'm using STM32F446RE to implement FatFS with Cube, using eval_sd.h file from F446RE_EVAL. I'm performing periodically writes in files and sometimes the code works, other it gives me a Hard fault at ff.c: validate, wh...
Posted on June 28, 2016 at 09:38Hi, I have a question concerning the STM32 Bootloader through an USB Host (flash drive). There is an Application note AN3354 doing this on the STM32F105, which is exactly my device. I just do not understand the memory...
Posted on June 27, 2016 at 11:18Trying to get a project with the subject line working in SW4STM32.However, if I try the fmount function with 0 (mount later), then fopen on a file, I get a not ready error. The same if I specify fmount with 1 (mount n...
