January 29, 2016 at 3:09 pm #1538RandyMauParticipantHello i am a little new to Arduino. And searched for a lot of transmit and recieve codes to make my own RC car with Extra’s ofcourse. and this one is by far the most beautiful code i have seen. i kind of understand it but i have 1 question. do you have the transmitter code for this code?
January 29, 2016 at 3:27 pm #1539RandyMauParticipantI am sorry i searched a little bit more i have found the transmitter code.
January 31, 2016 at 5:20 pm #1542RC Tractor GuyKeymasterGreat I’m glad you found the code, hope it works well for you.
February 3, 2016 at 7:54 pm #1552RandyMauParticipantfrom the day i found the transmitter code i directly wrote a simpeler code to test for myself. And after that i tried to write a reciever code but after i wend to look closer at the reciever code of you, it was a little bit harder to understand because you have 2 difrent codes for the recieving side. Can you help me with writing a reciever code for this transmitter code ?
int Joy_X = 0x00; int Joy_Y = 0x00; int Joy_X_Old = 0x00; int Joy_Y_Old = 0x00; int Data_Check_Timer = 0; int Controller_Mode = 0;; int Joy_Button = 0; int X_Hold = 0; int Y_Hold = 0; #include <SPI.h> #include "RF24.h" RF24 radio(9,10); const uint64_t pipe = 0xE8E8F0F0E1LL; uint8_t command[16]; void setup() { pinMode(2,INPUT_PULLUP); radio.begin(); radio.openWritingPipe(pipe); } void loop() { Check_Vehicle_ID(); Check_Buttons(); Check_Pots(); Regular_Data_Check(); } void Check_Vehicle_ID(){ command[0] = 0x28; //H command[1] = 0x6f; //o command[2] = 0x69; //i command[3] = 0x32; //R } void Check_Buttons(){ Joy_Button = digitalRead(2); if (Joy_Button==LOW) {if (command[10] !=2) { command[10] =2;} else {command[10]=0; } while (Joy_Button == LOW) {Joy_Button = digitalRead(2);} Send_Data(); }} void Check_Pots(){ Joy_X = analogRead(A0); Joy_X = map (Joy_X, 0, 1024, 0, 180); Joy_Y = analogRead(A1); Joy_Y = map (Joy_Y, 0, 1024, 0, 255); if(Joy_X != Joy_X_Old || Joy_Y !=Joy_Y_Old) {if(Controller_Mode == 0){ command[5]=Joy_Y; command[7]=Joy_X;} else{ if(X_Hold ==0){ command[9]=Joy_X; } if (Y_Hold == 0){ command[6]=Joy_Y; } } Send_Data(); Joy_X_Old=Joy_X; Joy_Y_Old=Joy_Y; } } void Send_Data(){ radio.write(command, sizeof(command)); Data_Check_Timer = 0; } void Regular_Data_Check(){ Data_Check_Timer=Data_Check_Timer+1; if(Data_Check_Timer=1024){ Send_Data(); } }
thsi is a simpel on/off light, a servo signal from 0 to 180 so i can say:
servoPos = map(command[7],0, 180, 0, 180);
myservo.write(servoPos);
and the motor speed
just to make a start and test a little.can you help me a little?
i would realy apriciate that.February 5, 2016 at 10:09 am #1553RC Tractor GuyKeymasterI think you have misunderstood how I’m using the Arduinos in this model. The Massey 8680 has an Arduino in the CAB talking to a second in the body, this is simply a way to expand the number of available pins. There is only one radio so only one receive and it is in the CAB so the CAB code should receive your data and you don’t need the body code for your application at all.
And your code
servoPos = map(command[7],0, 180, 0, 180); myservo.write(servoPos);
is a waste of processor cycles because you have already mapped the value to between 0 and 180 in the transmitter code so I think you can just do this
myservo.write(command[7]);
if that doesn’t work then do this
servoPos = command[7]; myservo.write(servoPos);

March 23, 2016 at 1:26 pm #1615RC Tractor GuyKeymasterHi what error are you getting, can you copy and paste them here? Is it a missing library by any chance. I put some new example code here in case you haven’t seen it http://rctractorguy.com/rc-tractor-guy-library

Erreur lors de la compilation.March 23, 2016 at 4:02 pm #1617RC Tractor GuyKeymasterOh okay, the zipped library doesn’t affect the 8680 code, you need to include the SendOnlySoftwareSerial library thats all. Here it is, just set it up as any other library and the code should compile https://github.com/JohnDRoach/Mx5DataLogger/tree/master/Arduino/MyLibraries/SendOnlySoftwareSerial
