This library is used to implement log output on the Arduino platform.Providing an output classification, positioning statement, formatted output function, the output of free memory.
#include <Logger.h>
#define LOG_LEVEL LOG_DEBUG
void setup()
{
Serial.begin(9600);
while (!Serial)
continue;
Serial.println(F("Run..."));
Logger log(&Serial);
log.setPrefix("[log]");
log.debug("Info %d",5);
log.debug("Info %c",'1');
log.error("Info %f",9.9);
log.error("Info %t",true);
log.info("Log library by NingQing,time: %s, version:%f \n","2021-5-7",1.0);

// [log] Info 5 file: src\main.cpp line: 13 level: D
// [log] Info 1 file: src\main.cpp line: 14 level: D
// [log] Info 9.90 file: src\main.cpp line: 15 level: E
// [log] Info true file: src\main.cpp line: 16 level: E

}
void loop()
{
// put your main code here, to run repeatedly:
}Output achieved by modifying the log level grade.
#define LOG_LEVEL LOG_OFF // no output
#define LOG_LEVEL LOG_DEBUG // can output: debug error info
#define LOG_LEVEL LOG_TEST // can output: error info
#define LOG_LEVEL LOG_RUN // can output: error
Logger can be bound to class objects that inherit Print to achieve output
Logger log(&Serial);- %s string (char*)
- %c char
- %d int
- %f double
- %t boole
- Execute the statement where the source file name and line number
- Free memory(Bit)
