Posted on September 13, 2014 at 02:22Dear all, i connected a 32.768Khz quartz to the external clock source (PC14, PC15), i would like to have an interrupt generated each second, for the system clock. Also, i connected a battery between VBAT and gnd,...
Posted on March 11, 2013 at 20:21Hello, Does anybody already used sdd1963 lcd controller with STM32 through FSMC? The used code to configure the FSMC is: void FSMC_LCD_Init(void) { FSMC_NORSRAMInitTypeDef FSMC_NORSRAMInitStructure; FSMC_NORSRAM...
Posted on July 29, 2014 at 14:44Hi.I use Nucleo board with STM32L0x3 MCU. There are special sequence for EEPROM TYPEPROGRAM_BYTE process? I can write 4 bytes data (TYPEPROGRAM_WORD) but can't write 1 byte data (TYPEPROGRAM_BYTE):uint32_t Address = 0...
Posted on September 06, 2014 at 22:11Hello, First, sorry for my poor english.I have a problem with a STM32F205. I am trying to read the content of flash memory , and for some bytes i have a value different with my firmware binary file. But the appli...
Posted on September 14, 2014 at 02:28I have a USB bootloader at address 0x08000000 that allows my STM32 to be programmed using dfu-util. I will eventually have my main firmware stored at 0x0800c000 and the bootloader will perform a ''jump'' to 0x080...
Posted on September 13, 2014 at 22:14I'v found in the Cortex-M4 file that the default value of PRIGROUP is 0. while the legal value of STM32 is from 3 to 7. And I didn't find the PRIGROUP set in startup file or system_stm32f4xx.c. What is the defaul...
Posted on September 12, 2014 at 11:22Can anybody point me to the software for programming STM32L0 family through USART bootloader? Flash loader demonstrator doesn`t seem to support this family.Thanks in advance #stm32l0-isp-bootloader
Posted on September 13, 2014 at 01:12 Hi, I am trying to create a 64MHz system clock by using the 8MHz HSI clock and the PLL (PLLMUL = 16). But the firmware stops working after this line: RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK);...
Posted on September 12, 2014 at 13:43Hi, My project crashed during programming of STM32L152 internal flash. Crashing means, that I cannot halt CPU; no hard fault nor bus fault interrupt only CPU freezed. Project runs CMSIS-RTX RTOS. Program is runni...
Posted on September 05, 2014 at 19:12 hi every body . i have systick in 25hz(each 0.04 sec) send my sensors data through usart. but the it just execute my main ''while(1)'' just once , and after that just my void SysTick_Handler(voi...
