8 Digit 7 Segment LED Display with SPI Interface

The following display features eight 7-segment displays arranged in two rows of four digits. The on-board MAX7219 driver enables you to easily add eight 7-segment LED displays to your project using only 3 I/O pins of microcontroller.


The major advantage of using this board is the time-division multiplexing operations required for continuous refreshing of the display digits are performed by the MAX7219 chip, thereby keeping the microcontroller free for doing other pressing tasks. It is suitable for displaying two variable values simultaneously in a project, such as displaying temperature and humidity, or current and voltage, etc.

How to Identify Mobile Phone Parts and Components

  1. Antenna Point: The point where antenna is connected is called antenna point. It is normally located at the top of the PCB of a mobile phone.
Network Section: The section below antenna point and above power section is called network section.
  
Antenna Switch: It is found in the network section. It is made from metal and non-metal. It has 16     points or legs. In some mobile phones, the antenna switch is merged with PFO. 

 

PFO: Power Frequency Oscillator. It is present beside the antenna switch. 

Network IC: It is below or beside the antenna switch and PFO. In some mobile phones, the Network IC is merged with the CPU. E.g.: Nokia 1200, 1650, 1208, 1209 etc.

 
Power IC: In the Power Section, the IC around which there are several brown-colored capacitors is called Power IC. In some mobile phones there are 2 Power ICs.  


 
CPU: Central Processing Unit. In the power section, the largest IC is the CPU. In some sets there are 2 CPU 
                                              Flash IC: This IC is found beside the CPU.



Logic IC: The IC with 20 legs is the Logic IC.



                  Charging IC: In the Power Section, the IC beside R22 is the Charging IC.
 

   Audio IC: The IC parallel to Power IC is the Audio IC


 
  1. UEM (Universal Energy Manager) = Logic IC + Charging IC + Audio IC + Power IC
  2. PFO (Power Frequency Oscillator) = Antenna Switch + PFO
  3. Flash IC= RAM + Flash IC
