Mini ScoreBoard sous Zround

**marco_losi** Ven 3 Oct 2014 - 11:03

Salut les zédeurs,

voici ma derniere création, un scoreboard pour Zround!! Enfin... Mini ScoreBoard, car le panneau d'affichage est sur une petite ligne de 6 caractères.

La verison filmé en démo affichage les meilleurs temps de chaques pilotes, mais les possibilités sont infinis!
Nombre de tour, classement, ecart, ... Le code embarqué est TRES flexible et permet de supporter des panneaux aussi grand que necessaire, multi-lignes aussi sans tout re-developper.

Et surtout en video:

Parametrage de Zround pour le faire fonctionner:

L'electronique est sans fil, donc lipo 2s + Bluetooth. J'ai hâte de faire un essai à mon lcub mardi prochain! bounce

Basically the system is based on a PIC micro programmed in C.
It does collect frames coming from Zround, sort, control and re-arrange them in internal RAM, then display the relevant info onto the dot matrix display with pause to have enough time to read the info.
The 6 dot matrix displays are daisy chained through one SPI port; meaning there is only one chip select for all displays, from hardware point of view it's really simple, the challenge rely on software side to generate the correct SPI 48bit frame. This display doesn't have hard coded font, so to fill the whole display the controller send the picture point by point which is 8x8x6 bit at a time.
