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) ,...
Posted on February 20, 2013 at 03:50I have made baseboard PCBs for the Discovery-F4, Discovery-F3 and Discovery-VL that break out the signals to separate connectors for various ports and interfaces. I am offering the PCBs for sale if you would find...
Posted on February 17, 2013 at 00:39 Hi all, I am using fatfs as file system and I need to handle the end of file but I didn't file something equivalent to while(! feof (golf)) In an example available on fatfs, the end of fi...
Posted on February 16, 2013 at 18:02 hi everyone, i want to make a simple comunication from usart2 to usart3, i have shorted usart2_tx (PA2) to usart3_rx (PB11). The program send 8bit from usart2 to usart3 and ceck if the transmitted dat...
Posted on February 15, 2013 at 20:48I use my STM32F0 to communicate with an SPI slave device, which is powered by the 3V bus on the STM32F0.My problem is that when I reset the STM32F0, the bus power is not interrupted, which leaves the SPI device in...
Posted on February 15, 2013 at 17:35Hi, I'm using CMSIS to set up an I2C driver. As an example device I have an EEPROM - tried and tested on PIC18s, so I've been through the learning curve for I2C - just getting it going on STM32. Configured CLS an...
