Posted on February 20, 2013 at 14:41Hi , A general question about fatfs and SDIO interface , i have a relative many read/seek operations in my program flow,and its taking a segnificant time of the all ''runtime''. Is there anyway to speed things up?...
Posted on January 24, 2013 at 08:24Hi all, STM32L processor does not start function with the PLL clock. External Oscillator (HSE) = 8Mhz. PLL clock source (PLLSRC) = HSE PLL multiplication factor (PLLMUL)= 6. PLL Division factor (PLLDIV)= 2. SYSCLK ...
Posted on February 20, 2013 at 15:12Hello, i only got one question: is it possible to connect one external analog input (PA3) to the COMP2 which is used as OPAMP and then use the Output (PA2) directly as input for the ADC and the COMP1?i need to amp...
Posted on February 19, 2013 at 21:52Hi guys,I have a problem with my new schede STM32F407VG. Until now I have been used the STM32F100B so now I'm adapting the code that I wrote. Part of my code is USART with interrupt, so I have wrote a code that re...
Posted on February 19, 2013 at 19:27Hi, I am having problem with the external memory. Not so long ago my program used both the internal memory and the external, but I managed to move both the heap and the stack to the external memory (2 megabyte) ,...
