Posted on May 17, 2011 at 13:30The reference manual says, ''When the I/O Port is programmed as Analog Input Configuration: â—� The Output Buffer is disabled. â—� The Schmitt Trigger Input is de-activated providing zero consumption for every analog v...
Posted on May 17, 2011 at 13:28Hello again, If you have an external pull up resistor, keep that GPIO high. If you have an external pull down resistor, keep that GPIO low. If you have an external pull up resistor, say 3k3 to 3.3V and pull it low exte...
Posted on May 17, 2011 at 13:28You may need to set up the GPIO pins with GPIOInit(). You need to enable the peripheral clock to the GPIO port with RCC_APB2PeriphClockCmd(). See main.c in the example GPIO_IOToggle in the peripheral library examples. ...
