==== 1. Socket for Bluetooth APC220 module ====

Description (from the top to the bottom):
    7 – not used
    6 – not used
    5 – pin 0
    4 – pin 1
    3 – not used
    2 – +5 V
    1 – GND
    
==== 2. LED display driven by 74HC595 ====

Datasheet 74HC595 is [[|here]].

Workflow:
    Write to Latch – PB5, LOW - begin of write, HIGH - end of write
    Clock pulse – PA8
    Serial data – PA9 – 2× 8 bits (2× Byte)

{{:courses:be2m37mam:hardware:index2.gif?100|}}

''1st Byte'' – segment data – LOW - LED segment in on,  HIGH - LED segment is off

''2nd Byte'' - display address (from the left):
    1. – ××××0001
    2. – ××××0010
    3. – ××××0100
    4. – ××××1000
 
Serial data order: from MSB (most significant bit) 

==== 3. Reset ====

Nucleo (Arduino) reset.

==== 4. LEDs ====
