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...
