接电机 可控制调整电机旋转方向 解决初始化时处理问题(每次启动时可获取的) 任务一:接电机 电机控制芯片:L298N(淘宝购) 电机供电:9V电池(淘宝购电池盒) 电机焊接电线定义如下 注:电机正负不知道怎么测,所以正负极先统一这么接根据控制调整接入L298N的OUT口就可以改变电机转动方向。 接线完成图 注:PS2无线手柄接收器同时还有一个带插针的,之前的那个准备 任务二+任务三(做) 附上代码: #include 《PS2X_lib.h》 PS2X ps2x; //right now, the library does NOT support hot-pluggable controllers, meaning //you must always either restart your Arduino after you connect the controller, //or call config_gamepad(pins) again after connecting the controller. int error = 0; byte type = 0; byte vibrate = 0; int count = 10; // 电机控制引脚; #define IN1 4 #define IN2 5 #define IN3 6 #define IN4 7 void setup(){ //初始化针脚 pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT); pinMode(IN3, OUTPUT); pinMode(IN4, OUTPUT); Serial.begin(57600); while(count 》 0){ count--; error = ps2x.config_gamepad(13,11,10,12, true, true); //GamePad(clock, command, attention, data, Pressures?, Rumble?) if(error == 0){ Serial.println(“Found Controller, configured successful”); Serial.println(“Try out all the buttons, X will vibrate the controller, faster as you press harder;”); Serial.println(“holding L1 or R1 will print out the analog stick values.”); Serial.println(“Go to www.billporter.info for updates and to report bugs.”); break; } else if(error == 1) Serial.println(“No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips”); else if(error == 2) Serial.println(“Controller found but not accepting commands. see readme.txt to enable debug.

Other options: LX, RY, RX Serial.print(“,”); Serial.print(ps2x.Analog(PSS_LX), DEC); Serial.print(“,”); Serial.print(ps2x.Analog(PSS_RY), DEC); Serial.print(“,”); Serial.println(ps2x.Analog(PSS_RX), DEC); } } delay(50); } 因为不是每次启动初始化的时候都可以检测到手柄,所以加了一次设置,10次,尝试10次,就找不到了手动重启!**** 手动重启!**** 手动重启!。作者尝试了自己无法完成的问题。计数值。查找手柄程序会跳出查找手柄操作的,继续执行停止的代码。 注。调整电机控制:按本文中的接线方式应该不需要调整。如果是乱走的话,则需要轮子的方向调整电机与298N的接线。 |
