How to Use an I²C Driver?For better readability of the Robo Pro program and faster development, a good approach consists on using drivers.
A driver contains specific ready-to-use functions to talk with the corresponding I²C device. Robo Pro 3.1.3 comes with a specific directory with drivers for a wide selection of the most popular I²C devices. |
How to Import a Driver
|
Just start with a new empty project.
|
|
|
Click on File > Open and select the directory with the drivers for I²C devices.
This directory is located at 
Choose the device and load it.
|
|
|
Here, the driver for the real time clock DS1307 appears under Element groups > Loaded programs.
The corresponding functions are below, under Program elements. |
|
|
Just click-and-drag the function from the right column to the working space.
Note that the DS1307_get automatically imported the sub-function BCD_DEC it uses. |
|
|
Proceed as normal and add your own variables and commands.
Your program is ready now! |

What's Inside a Driver?
|
A driver is a standard Robo Pro project file with all the functions to talk with the corresponding I²C device.
If the functions require so, sub-functions are also included. As any other Robo Pro project, it has a main program and functions. As seen before, we use only the functions. The main program provides an example. Using that example to get familiar with the I²C device is a good idea. |
