Posted on September 21, 2011 at 05:20Hi, Vrefint � Looking for a better description of how this voltage is formed/used. When using an external Vref+, is Vrefint tied to it or to VDDa? How would we expect the PVD and BOR functions to operate if Vre...
Posted on September 14, 2011 at 17:31 Hi, does anyone knows why the RxCounter in the interrupt routine always up-counting even the STM32 does not get into interrupt? I am trying some example codes about the USART. All the settings are the as usual...
Posted on September 17, 2011 at 14:55Hi.I am a student and i must do a project with the STM32L-Discovery using SPI.I found this code:/** * @brief Changes the mapping of the specified pin. * @param GPIOx: where x can be (A, B, C, D, E or H) to se...
Posted on September 19, 2011 at 18:09Hi, I tried to flash an stm32w108 with JLINK but i get an error: Error: Wrong AHB ID (15:3). Expected 0x04770001 (Mask 0x0FFFFFCF), Found 0x00000000 i want to know how could I solve this problem. Sure my microco...

Posted on September 17, 2011 at 12:53Hello,I have an application where I have 2 sources that wake my STM32F from STANDBY: RTC and wakeup pin. Both work well as designed (they wake my MCU from STANDBY) but I cannot get the flag to tell what caused th...
Posted on September 18, 2011 at 22:38I have observed a conflict between SPI1 and DAC1 on stm32f103ZG micro. When spi1 is initialized first and then DAC1 the spi1 clock shuts down. It is time sensitive, but I manage to make repeatable on stm3210E-EV...
Posted on July 02, 2011 at 16:15Hello, I try turn on and turn off a led when i press the button user1 but can not to do that, So i don´t understand my mistake. I m using Keil with stm32_init.c, i config GPIOA.PIN1 like floating input... the main co...
