This post is part 3 of 9 of \u00a0AD4M4ST0R - um rover LEGO<\/a><\/div>

O gamepad utilizado no AD4M4ST0R<\/a> \u00e9 um “Gioteck VX-2 Wireless Controller<\/a>” comprado na FNAC por \u20ac19.99. Qualquer modelo compat\u00edvel com PC dever\u00e1 funcionar, desde que use um dongle USB (os modelos por cabo USB tamb\u00e9m funcionar\u00e3o mas n\u00e3o servem para o caso). Quando o stack bluetooth estiver funcional no ev3dev tamb\u00e9m dever\u00e3o funcionar gamepads desse tipo<\/p>\n

\"gamepad\"<\/a>O gamepad \u00e9 reconhecido automaticamente como um gamepad e como um disposito de classe OHCI:<\/p>\n

\u00c0 custa deste script fiquei a saber que o gamepad tem 4 axes (2 por cada joystick anal\u00f3gico), 13 buttons e 1 hat (o hat \u00e9 o conjunto de 4 teclas direccionais \u00e0 esquerda do gamepad) que quando accionados devolvem:<\/p>\n
Para cada um dos 13 bot\u00f5es:<\/p>\n
gatilho esquerdo = 6
\nbot\u00e3o sobre gatilho esquerdo = 4
\ngatilho direito = 7
\nbot\u00e3o sobre gatilho direito = 5
\nselect = 8
\nstart = 9
\nhome = 12
\ntriangulo = 0
\ncirculo = 1
\ncruz = 2
\nquadrado = 3
\nbot\u00e3o do joystick esquerdo = 10
\nbot\u00e3o do joystick direito = 11<\/p>\n
(o bot\u00e3o “Turbo’ ao centro do gamepad parece n\u00e3o funcionar)<\/p>\n
Para cada um dos 4 bot\u00f5es do hat:<\/p>\n
cima = (0,1)
\ndireita = (1,0)
\nbaixo = (0,-1)
\nesquerda = (-1,0)<\/p>\n
Para o joystick da direita:<\/p>\n
todo para cima: Eixo 3 = -1
\ntodo para baixo: Eixo 3 = 1
\ntodo para direita: Eixo 2 = 1
\ntodo para esquerda: Eixo 2 = -1
\n=> (x,y) = (axis2,-axis3)<\/p>\n
Para o joystick da esquerda:<\/p>\n
todo para cima: Eixo 1 = -1
\ntodo para baixo: Eixo 1 = 1
\ntodo para direita: Eixo 0 = 1
\ntodo para esquerda: Eixo 0 = -1
\n=> (x,y) = (axis0,-axis1)<\/p>\n
O gamepad tem tamb\u00e9m um motor interno para vibra\u00e7\u00e3o (force feedback?) mas que s\u00f3 funciona com Playstation 3. Curiosamente de vez em quando acontece-me poucos minutos depois de desligar o EV3 o gamepad desatar a vibrar.<\/p>\n","protected":false},"excerpt":{"rendered":"

O gamepad utilizado no AD4M4ST0R \u00e9 um “Gioteck VX-2 Wireless Controller” comprado na FNAC por \u20ac19.99. Qualquer modelo compat\u00edvel com PC dever\u00e1 funcionar, desde que use um dongle USB (os modelos por cabo USB tamb\u00e9m funcionar\u00e3o mas n\u00e3o servem para o caso).
