hello,

In recently , I have a PV750 project with customer requiry with following what I don't know how to program:

1. While the display sees a reverse gear signal throght CAN what is broadcasted by Transmission system, the display will go to video screen automatically . Vice versa , while the display sees a forward gear signal, then display will be back to Home screen.

2. Can our display system handle .pdf format file ? In other words, can I import a .pdf format instruction into display for the operator?

3. Can we have a configuration with the function about changing the setpoint of fuel level when the fuel level was read by the input of our display?

Thanks.

Hello Terry,

1. You can show the video screen when the gear is reverse using state machines with these states:
A state that executes the action UIApp->Show View() to show the video screen.
The transition going to this state needs an event condition that checks that the gear is reverse.

A state that executes the action UIApp->Show View() to show the home screen.
The transition going to this state needs an event condition that checks that the gear is forward.

A state that executes the event conditions to enter the other states.
The transition going to this state needs to fire on change when the gear variable changes.

2. You cannot import a .pdf file but you can convert the .pdf to a .png, import the .png and show it with an image widget.

3. You can change the fixed values in the formula that calculates the fuel level from the analog input or you can change the formula to use variables instead of fixed values and that way the user can change the variables in the display.

Hello Terry,

I attached a configuration to demonstrate how to show the video page when the current gear is reverse.
