Would you guys help me to fix this? the output shows "Compilation error: too many initializers for 'Perintah'" thank you

Post your sketch, well formated, with well-tempered comments and in so called code tags "< code >" to see how we can help.

[b707]

Addition to the formatting the code, please explain what the problem you have with it. If there are a compile errors, please insert them in full using the code tags.

[horace]

upload a schematic showing the wiring in particular how you power the Ebyte E220 LoRa and other devices
I assume you are using LoRa P2P communication have you tested the E220 in a seperate program?
does the program compile and run? if so upload a copy of the Serial Monitor output - it is always worth adding extra Serial.println() statements to display variable values at key points in the program execution

Would you guys help me to fix this?

Very generalised question. So much generalised that the very generalised answer is:

Yes.

the output shows
"Compilation error: too many initializers for 'Perintah'"

[StefanL38]

Still only very poor information:

You are trying to be quick by quick and short postings. All that happens is that you are slowing things down, because all that happends is asking back that you provide the information that you thought leave it away to be quicker

If you get a compiler-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to pos…

struct Perintah
{
  char type[5];
  char command[8];
  int VPIN_BUTTON_1[8];
  int VPIN_BUTTON_2[8];
  int VPIN_BUTTON_3[8];
} perintah = {"", "", "", "", "", ""};

the structure has five members and you have six initialisers
try

struct Perintah
{
  char type[5];
  char command[8];
  int VPIN_BUTTON_1[8];
  int VPIN_BUTTON_2[8];
  int VPIN_BUTTON_3[8];
} perintah = {"", "",{0},{0},{0}};

as perintah is global it initial values will be set to 0 by default anyway

I suspct you have many errors reported by the compiler - upload the complete compiler error report??

[b707]

@meidyf

struct Perintah command = {" "};
	

You should use keyword struct only when you want to defene a new type.
Do not use this keyword when you define a new variable of previsly defined type Perintah as in line above.

[horace]

implement a simple program to test structure initialisation, e.g. using a NodeMCU ESP8266

struct Perintah
{
  char type[5];
  char command[8];
  int VPIN_BUTTON_1[8];
  int VPIN_BUTTON_2[8];
  int VPIN_BUTTON_3[8];
} perintah = {"", "",{0},{0},{0}};

struct Perintah command = {" "};

struct Perintah test = {"tst1","test2",{1,2,3},{7,8,9},{10,1,12}};

void setup() {
  Serial.begin(115200);
  Serial.println(test.command);
  Serial.println(test.VPIN_BUTTON_1[0]);
  Serial.println(test.VPIN_BUTTON_2[2]);
  Serial.println(test.VPIN_BUTTON_2[6]);
}

void loop() {
  Serial.println(test.VPIN_BUTTON_3[2]++);
  delay(2000);
}

serial monitor displays
