The display .

Off course , the results of the calculations have to be shown so the user knows the values of the RPM , the torque and the standard deviation on the torque . We choose to show them on a display .

At first , a display was given to us . This was a 16 character LCD , but 16 characters isn’t enough to display all the values that were requested . So we decided to buy another display and keep the first one to perform tests on . Unfortunately , when we tried to test some of the programs , we noticed that the display was defect and so we never got to use it .

The 16 character display

We bought another display , one with 2 lines of each 16 characters , namely the MTC-C162DPLY-2N of the company Truly .

The 32 character display

A datasheet of this LCD can be found on following address :

Extra information for this product , concerning the electronical connections , can be found on following address :

This is a device that requires an ASCII code as input and then displays the required character . Unfortunately , our display doesn’t have a blacklight , because that model was sold out but the principle is exactly the same .
