// Note: Commented lines are alternative possibilities which are not used per default.

|

// Notes
|
||||
//
|
||||
// - 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.
