Posted on June 09, 2016 at 17:44 Hi everyone, i'm trying to start playing with STM32F7 Discovery board, taking as base the benchmark project and modifying it. i did the following modification in stm32f746g_discovery.c:
GPIO_InitTypeDef GPIO_Init_Structure;
GPIO_Init_Structure.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_Init_Structure.Pull = GPIO_NOPULL;
GPIO_Init_Structure.Speed = GPIO_SPEED_HIGH;
/*GPIO_Init_Structure.Alternate = GPIO_AF12_FMC;*/
/* GPIOD configuration */
GPIO_Init_Structure.Pin = GPIO_PIN_1 | GPIO_PIN_5;
HAL_GPIO_Init(GPIOI, &GPIO_Init_Structure);
in main, i added the following:
if (BSP_PB_GetState(BUTTON_KEY)) {
HAL_GPIO_WritePin(GPIOD,GPIO_PIN_5,GPIO_PIN_SET);
}
else {
HAL_GPIO_WritePin(GPIOD,GPIO_PIN_5,GPIO_PIN_RESET);
}
i can see in the, debbuging sesion, GPIOD ODR pin 5 going up and down, but the physical pin (OTG_FS_PowerSwitchOn) remains up without toggling.
any clue why is this?
thanks in advance
