Question

我有一个Arduino开发板ATmega2560，我想在上面编写汇编代码。我用C语言编写了一些代码，用于使用温度传感器在LCD16x2上显示温度。但是这次我想用相同的功能编写代码，但这次是在Assembler中。我对汇编程序很陌生，我想知道应该如何开始，也许有人可以帮助我将当前代码转换为汇编程序？我找不到该板的太多教程。我的C代码如下：

#include <LiquidCrystal.h>

int tim = 50;                       //the value of delay time
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(4, 6, 10, 11, 12, 13);
int thermistorPin = 0;           // thermistor connected to analog pin 3

void setup()
{
  lcd.begin(16, 2);    // set up the LCD's number of columns and rows: 
  lcd.clear();         //Clears the LCD screen and positions the cursor in the upper-left corner 
}

void loop() 
{
   float a = analogRead(thermistorPin);
  //the calculating formula of temperature
  float resistor = (1023.0*10000)/a-10000;
  float tempC = (3435.0/(log(resistor/10000)+(3435.0/(273.15+25)))) - 200.00;

  lcd.setCursor(0, 0); // set the cursor to column 0, line 0
  lcd.print(" THIS IS A TEST ");// Print a message of "Temp: "to the LCD.

  lcd.setCursor(0, 1); // set the cursor to column 0, line 0
  lcd.print("  Temp: ");// Print a message of "Temp: "to the LCD.
  lcd.print(tempC);// Print a centigrade temperature to the LCD. 
  lcd.print(" C  "); // Print the unit of the centigrade temperature to the LCD.
  delay(500);
}

Arduino ATMega2560使用汇编程序代替C
