I2C must be enabled in order to
communicate with the RTC. See
section 11 I2C to enable it.
Using the boards of Industrial Shields, there is a library that simplifies the RTC implementation
called RTC.
10.8 uSD
The micro SD uses the SPI communication to interact with the Arduino Mega. The SPI protocol
is always enabled, as there are no switches that configure it. However, there is a switch that
must be placed to ON mode in order to communicate with the uSD:
D53(SD): If this Switch is OFF, it enables the Chip Select of the microSD socket and disables
Q2.0. If this switch is ON, it enables the Q2.0 output. If the switch is in ON mode the microSD
can’t be used.
The uSD socket is found in the TOP part of the communication Shields, so in the frontal part of
the PLC, it is required to open the plastic found in the frontal part and the socket is located
under the supply of the Arduino.
Using the boards of Industrial Shields, there is a library that simplifies the uSD implementation
called SD. It is the same as the Arduino library, with the only modification of using the pin 53 to
select the Chip Select of the uSD chip.
