 ### I2C DISPLAY
-The I2C display module is a wrapper over the HAL methods that are already provided. For this project, the simulated display 16x2 (LCD Module 1602A) has been connected to the first peripheral with the 0x34 address, since it has been considered with mounted a PCF8574 I$^2$C interface in order to reduce the number of used pins.

 By referring to the [https://www.openhacks.com/uploadsproductos/eone-1602a1.pdf](LCD Module 1602A datasheet), all the commands are managed in 10 bits, in which the MSBs define the command and the LSBs the configuration.
 In order to abstract from the complexity of the command management, the hexadecimal representation of each one of the has been put in the `i2c_lcd.h` header file.
 The setup procedure of the display is based on sending a precise sequence of bits with the correct timing, in order to switch from the 8 to 4 bits mode. The steps are the following:

 It's important to specify that all the previous commands are send in a specific manner, so that the controller on the LCD can understand if them. Commands are sent as 4 bytes, where the first and the second byte of the initial command are split and duplicated in 4 bytes and then an or logic operation is performed to set the backlight and if the display is enabled.
 
 Starting from a defined location on the 16x2 matrix, characters can be sent one by one by sending their byte representation.
-In order to make the simulated environment complete, a simulated LCD has been developed in C\# with the Mono framework that is an open source implementation of Microsoft's .NET Framework. In this way, Form can be directly created from the C# of the custom peripheral. An image is loaded as background and each of the 16x2 characters are manged as a 5x8 dot matrix.

 Not only the normal chars has been implemented but, since a normal LCD display has an internal memory that allows to store up to 5x8 custom char definition, the simulator and the firmware has been enhanced with this additional feature.
