//==============================================================================
// Notes
//
// - The pins mentioned 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.
//
// - Warning: pins connected to the default STDIO_UART_TX and STDIO_UART_RX pins are commented
// See https://os.mbed.com/teams/ST/wiki/STDIO for more information.
