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...
Posted on September 11, 2014 at 20:01Am I missing something or flash loader demonstrator 2.6 doesn`t support STM32L0x devices?Seems that there is no appropriate *.map file for that family. #stm32l0-flash-loader-demonstrato
Posted on September 12, 2014 at 09:12I'm reluctant to post this because I figure it's operator error, but I'm stuck. I'm running an STM32F407 Discovery board using AdaCore's Ada2012 release. Simple tasks seem to run correctly, and at the correct s...
Posted on September 11, 2014 at 14:52Hello all,I am trying to establish SPI communication bw STM32FDiscovery board and MCP3202 ADC. The optimum clock rate of MCP3202 is given as 10kHz in the datasheet. I am using SYSCLK as 48MHz in my Discovery boar...
Posted on September 12, 2014 at 12:47In a nearly ready project i wanted to add some more types of TFT displays. Now i�ve got one with an SSD1298 controller, for which well working init-code is available. I connected it in well known manner to the FS...
Posted on September 11, 2014 at 19:54Hi, I'm using an olimex stm32e407 board. I select the option lwip but with FW_F4_1.3.0 dont work, ping without success. But if i select in the stm32cubeMX the FW_F4_1.1.0 the ping work. I don't understand why. R...
