im trying to build a bit of test equipment that will talk to some software and it needs to send a fix string. when the voltage changes the string length does as well. i need to cap the results to 4 in length. (sorry for not knowing the correct terminology. this is the output i need - <X_PCCCC_Y_PFFFF_Z_PTTTT> Where,

X = Flag CP Value
_ = Space
P = Polarity
C = CP Received value
Y = Flag Field Gradient
F = Field Gradient Received value
Z = Flag Contact CP
T = Contact CP Received value

There is also a line feed and carriage return present at the end of each string. The polarity indicator will only display a minus sign ‘-‘ if the received value is negative otherwise no assignation will be transmitted. Although the overall string length is constant the values for each measurement are right justified and hence a space will be present should the value of the measurement not necessitate the utilisation of all allocated character spaces. Sample Outputs

< X -89 Y -1989 Z -1096 > < X 1039 Y 8 Z 78 >

this is my code so far

#include <Wire.h>
#include <Adafruit_ADS1015.h>
Adafruit_ADS1115 ads1(0x48); /* Use this for the 16-bit version */
Adafruit_ADS1115 ads2(0x49);
void setup(void){
 
 Serial.begin(9600);
 
 ads1.setGain(GAIN_ONE); // 1x gain +/- 4.096V 1 bit = 2mV 
 ads2.setGain(GAIN_ONE); // 1x gain +/- 4.096V 1 bit = 2mV 
 
 ads1.begin();
 ads2.begin();
}
void loop(void){
 int16_t results01,results02,results03;
  
 results01 = ads1.readADC_Differential_0_1();
 results02 = ads1.readADC_Differential_2_3();
 results03 = ads2.readADC_Differential_0_1();
  
 Serial.print("X "); 
 Serial.print(round(results01 * multiplier));
 
 Serial.print(" Y "); 
 Serial.print(round(results02 * multiplier)); 

 Serial.print(" Z "); 
 Serial.print(round(results03 * multiplier));
 Serial.println(); // send a cr/lf
delay(500);
}

Any help pointing me in the right direction would be Amazing. Thanks in advance
