Posted on December 02, 2015 at 10:28 Hello there, I was wondering either it is possible to count with microseconds resolution isntead of seconds resolution using RTC 32k clock? I am using HAL lib. In theRTC_TimeTypeDef time structure t...
Posted on December 07, 2015 at 11:51Hi, unfortunately I am unable to get STM32-MAT/TARGET working with Simulink in PIL-mode. :( I had trouble to get code generation working with STM32-MAT-TARGET as well. I have tested it with three different MATLAB ...
Posted on December 08, 2015 at 08:56Hello, in one of the projects my device regulary goes to standby and I need a place to buffer the data. Since the F4 series do not have so many small sectors and the program already takes over the first 4 smallest...
Posted on November 07, 2015 at 15:11Hello, Why only 64Mbit are accessible on the board ? Why the board was not designed with 16bit-wide SDRAM ?
Posted on December 07, 2015 at 15:33Hello there,I am using stm32f407vtg (1MB flash). Apart from user program, I need to store some additional data in the flash memory. I need 3 banks: 1kB, 16 kB and 64 kB. I just expirienced that I need to erase who...
Posted on December 07, 2015 at 18:24Hi to all, I realized my first pcb using a STM32F030K6 MCU. The project is a very simple one, that is no external oscillator, only two leds and a usart interface.I can regularly download the program using ''flash ...
Posted on December 07, 2015 at 17:13Hi have a SRAM Disk working using FATFS and USB. I can read and write files to the disk from my processor (STM32f427zit) but the files do not get updated in windows explorer on the PC. If if unplug the USB and th...
Posted on December 04, 2015 at 12:47I'm using STM32F411RE board and trying to communicate with SIM900 over UART. I'm simply trying to send.I put some parts of my code and would appreciate your help. I think there's some configuration issue in UART p...
Posted on December 07, 2015 at 09:27Hi All,Attempting to clear a pending bit in the EXTI_PR1 register via its bit banding alias clears another pending bit as well. When I try to clear the bit20 (RTC periodic alarm) after wakeup by writing 1 to its a...
