CPU BOARD
4.2.1. Description of the module
The CPU board allows for controlling and managing all the peripheral units connected to the same,
processing the data supplied regarding the read sensor boards and calculates the Westergren value at
the 1
st
and 2
nd
Hours and the Katz index of every sample examined.
This is mainly subdivided into the following blocks:
1) MPU and ADDRESS/DATA BUS CONTROL block
[U2- ATMEGA 128]
This block consists of microcontrollers that carry out the functions dictated by the programme
residing in the same. It has a 16 Mhz system clock and a bus speed of 16 Mhz (speed of carrying
out an operation).
2) MEMORY block
[U2]
FLASH-Eprom Integrated in the microprocessor where the management programme is housed, the
capacity of which is 128 KByte x 8Bit where the MPU transfers data or variable in a temporary
manner with entirely random access.
