// Note: Commented lines are alternative possibilities which are not used per default. // Notes
// If you change them, you will have also to modify the corresponding xxx_api.c file //
// for pwmout, analogin, analogout, ... // - The pins mentionned Px_y_ALTz are alternative possibilities which use other
// ===== // HW peripheral instances. You can use them the same way as any other "normal"
// pin (i.e. PwmOut pwm(PA_7_ALT0);). These pins are not displayed on the board
// pinout image on mbed.org.
//
// - The pins which are connected to other components present on the board have
// the comment "Connected to xxx". The pin function may not work properly in this
// case. These pins may not be displayed on the board pinout image on mbed.org.
// Please read the board reference manual and schematic for more information.
