We were using PZEM-004T v3.0, energy meter library within the code format of C++.
And for the compilation proccess,we use Arduino IDE.
So,the example codes were in ino format.During the compilation, the example code executed successfully with the help of Arduino IDE.
And for the next stage of execution, we need to convert these C++ & ino codes into 'C code' to perform compilation in CLION and Cmake.
Example code for PZEM-004T v30:
Code in .ino :
#include <PZEM004Tv30.h>
/* Hardware Serial3 is only available on certain boards.
* For example the Arduino MEGA 2560
*/
//PZEM004Tv30 pzem(&Serial2);
HardwareSerial PzemSerial2(2); // Use hwserial UART2 at pins IO-16 (RX2) and IO-17 (TX2)
PZEM004Tv30 pzem(&PzemSerial2);
void setup() {
Serial.begin(115200);
}
void loop() {
float voltage = pzem.voltage();
if(!isnan(voltage)){
Serial.print("Voltage: "); Serial.print(voltage); Serial.println("V");
} else {
Serial.println("Error reading voltage");
}
float current = pzem.current();
if(!isnan(current)){
Serial.print("Current: "); Serial.print(current); Serial.println("A");
} else {
Serial.println("Error reading current");
}
float power = pzem.power();
if(!isnan(power)){
Serial.print("Power: "); Serial.print(power); Serial.println("W");
} else {
Serial.println("Error reading power");
}
float energy = pzem.energy();
if(!isnan(energy)){
Serial.print("Energy: "); Serial.print(energy,3); Serial.println("kWh");
} else {
Serial.println("Error reading energy");
}
float frequency = pzem.frequency();
if(!isnan(frequency)){
Serial.print("Frequency: "); Serial.print(frequency, 1); Serial.println("Hz");
} else {
Serial.println("Error reading frequency");
}
float pf = pzem.pf();
if(!isnan(pf)){
Serial.print("PF: "); Serial.println(pf);
} else {
Serial.println("Error reading power factor");
}
Serial.println();
delay(2000);
