How to use Text Value Display

[Nils.Sky]

Hey, thanks for your fast reply!

Unfortuately it doesnt work...

This is my full code 

#include "VirtuinoCM.h"
VirtuinoCM virtuino;
#define V_memory_count 32 // the size of V memory. You can change it to a number <=255)
float V[V_memory_count]; // This array is synchronized with Virtuino V memory. You can change the type to int, long etc.
boolean debug = true; // set this variable to false on the finale code to decrease the request time.
String V16 = "Hello";
//============================================================== setup
//==============================================================
void setup() {
if (debug) {
Serial.begin(9600);
while (!Serial) continue;
}
String V16 = "Hello";
Serial.begin(19200);
Serial1.begin(9600);
Serial1.setTimeout(50);


virtuino.begin(onReceived,onRequested,256); //Start Virtuino. Set the buffer to 256. With this buffer Virtuino can control about 28 pins (1 command = 9bytes) The T(text) commands with 20 characters need 20+6 bytes
//virtuino.key="1234"; //This is the Virtuino password. Only requests the start with this key are accepted from the library

pinMode(4, OUTPUT); // On Virtuino panel add a button to control this pin
pinMode(13, OUTPUT); // On Virtuino panel add a button to control this pin
pinMode(6, INPUT); // On Virtuino panel add a led to get the state of this pin
pinMode(7, INPUT); // On Virtuino panel add a led to get the state of this pin
}
//============================================================== loop
//==============================================================
void loop() {
virtuinoRun();




vDelay(1000); // This is an example of the recommended delay function. Remove this if you don't need
Serial.println("V16"+V16);
}








//============================================================== onCommandReceived
//==============================================================
/* This function is called every time Virtuino app sends a request to server to change a Pin value
* The 'variableType' can be a character like V, T, O V=Virtual pin T=Text Pin O=PWM Pin
* The 'variableIndex' is the pin number index of Virtuino app
* The 'valueAsText' is the value that has sent from the app */
void onReceived(char variableType, uint8_t variableIndex, String valueAsText){
if (variableType=='V'){
if (variableIndex<V_memory_count) {
float value = valueAsText.toFloat(); // convert the value to float. The valueAsText have to be numerical
V[variableIndex]=value; // copy the received value to arduino V memory array
}
else if (variableIndex== 16 ) V16= valueAsText;

}
}
//==============================================================
/* This function is called every time Virtuino app requests to read a pin value*/
String onRequested(char variableType, uint8_t variableIndex){
if (variableType=='V') {
if (variableIndex<V_memory_count) return String(V[variableIndex]); // return the value of the arduino V memory array
else if (variableIndex==16) return V16;

}
return "";
}
//============================================================== virtuinoRun
void virtuinoRun(){
while (Serial1.available()) {
char tempChar=Serial1.read();
if (tempChar==CM_START_CHAR) { // a new command is starting...
virtuino.readBuffer=CM_START_CHAR; // copy the new command to the virtuino readBuffer
virtuino.readBuffer+=Serial1.readStringUntil(CM_END_CHAR);
virtuino.readBuffer+=CM_END_CHAR;
if (debug) Serial.println("\nCommand= "+virtuino.readBuffer);
String* response= virtuino.getResponse(); // get the text that has to be sent to Virtuino as reply. The library will check the inptuBuffer and it will create the response text
if (debug) Serial.println("Response : "+*response);
Serial1.print(*response);
break;
}
}
}

//============================================================== vDelay
void vDelay(int delayInMillis){long t=millis()+delayInMillis;while (millis()<t) virtuinoRun();}



I am using virtuino cm 1.0.2. 


Serial Monitor Output is:

13:11:13.729 -> V16Hello



13:11:13.729 ->



13:11:13.729 -> Command= !V16=?$



13:11:13.729 -> Response : !V16=0.00$



13:11:13.729 -> V16Hello



13:11:13.729 -> V16Hello


It also prints the Value of V[16] in my text value display...

Hope this clarifies it a bit
