Posted on July 24, 2014 at 05:13HI,I have faced one problem with PORTF pin configuration (PF0,PF1).My GPIO configuration:RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOF, ENABLE); InitGpio.GPIO_Pin = (GPIO_Pin_0 | GPIO_Pin_1 ); InitGpio.GPIO_Mode = GPIO_Mo...
Posted on July 25, 2014 at 12:44Hi all, I have to interface external oscillator to stm32f407igt6 which is having 16Mhz internal frequency and i need to boost it to 168Mhz frequency by connecting a 25Mhz external oscillator so can anyone giv...
Posted on April 30, 2014 at 04:45 hi, I have a custom designed board with STM32F07 IC. The FSMC interface is working with certain version of software. recently i tried to use CubeMX to generate low-level code with FSMC HAL. I only added a...
Posted on July 25, 2014 at 02:53What is the use of the GPIOx_MODER Alternate function mode? Is it needed when an appropriate non-zero value is put into GPIOx_AFRL/H? Is the GPIOx_MODER alternate function mode value only needed for those few altern...
