I need to create an app with sdl2 to use it on Raspbian running outside startix

and be free in the future to use it on other linux operating systems.

The app is a Queue Management System that works in this way:

1) at the start it show the number 00

2) right arrowkey: grow the number of one step, so for exampe ->1 -> 2 -> etc.. till 99

3) left arrow key: reset the number restarting it from 00


- permit the option to show a letter before the number, so for example then the counter would looks like this:

P01,P02 etc...

- define the file name name of the true type font font to use (all the used fonts are stored in the same folder)

- position of the text in pixel: X-Y

- color of the text

- dimension of the text

- define the filename of the .png file(24+8 alpha) 32 bit that will works as a mask in foreground

- give a unique id to the QMS

- Every Queue Management System has 3 options:

option 1) only show the QMS managed from the arrow keys

option 2) don't show any text produced form the arrow keys

and only listen the tcp socket to receive informations to show one ore more QMS on the same display, on the same layer

option 3) show the QMS managed from the arrow keys

plus send the configuration and the number to show to one or more devices in the LAN trough the tcp socket


use the layer raspberry framebuffer graphicsdriver 3

we use Raspberry Pi Model 3B and B+ with raspbian

the devices will be resetted to the counter 00 daily, rebooting the os

when needed I will give the link with instructions about how to compile the driver for raspberry GPU
