我得到了彩色 LCD Shield https://www.sparkfun.com/products/9363
并尝试了一些代码来运行程序,但因为我是 arduino lcd 项目的新手。我没有我应该如何更改代码?这是来自的代码:

/***************************************************
This is an example for the Adafruit Thermocouple Sensor w/MAX31855K
Designed specifically to work with the Adafruit Thermocouple Sensor
----> https://www.adafruit.com/products/269
These displays use SPI to communicate, 3 pins are required to
interface
