/*
增加"EEPROM"和"RESET." 指令，可以给标签命名为指令的名字，点击标签即可执行
关于"EEPROM"指令:查看EEPROM内容
关于"RESET."指令：重置EEPROM *警告！ 你会失去所有烙铁头的温度校准数据!!!
Add "EEPROM" and "RESET." to give the label the name of the instruction. Click the label to execute
Regarding "EEPROM" instruction: View EEPROM contents
Regarding "RESET." instruction: RESET EEPROM
* warning! You will lose all the temperature calibration data for the tip of the soldering iron!!
*/
// Power supply should be in the range of 16V/2A to 24V/3A and well
// stabilized.
//
// For calibration you need a soldering iron tips thermometer. For best results
// wait at least three minutes after switching on the soldering station before
// you start the calibration process.
//
// Controller: ATmega328p
// Core: Barebones ATmega (https://github.com/carlosefr/atmega)
// Clockspeed: 16 MHz external
