一、网上找到最便宜的板子
https://item.taobao.com/item.htm?spm=a1z09.2.0.0.2c802e8dP0EmQg&id=648413912304&_u=i1sscgpi56c8
13.8包邮
二、获取资料
- 可以选择TB详情页上给的库，也可以拿
nulllab的库
地址：
https://gitee.com/nulllab/nulllab_arduino
三、开搞
- 在附加开发板管理器网址输入如下网址
https://cdn.jsdelivr.net/gh/nulllaborg/arduino_nulllab/package_nulllab_boards_index_zh.json - 开发板选DLY BOARD
- 配置如下：
注意点：
时钟必须是16M，否则定时都不准
必须采用内部32M
EEPROM必须选择 有 ，大小随意，不然会编译报错
上传波特率不能是115200，可能这颗USB转TTL不太行
Clock Source：Internal 32M
Frequency： 16M
Variant：LGT328P-LQFP32
EEPROM SIZE：2KB
Upload Speed：57600
四、简单例子
-
LED闪烁，具体引脚可以看

/* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of your board at: https://www.arduino.cc/en/Main/Products modified 8 May 2014 by Scott Fitzgerald modified 2 Sep 2016 by Arturo Guadalupi modified 8 Sep 2016 by Colby Newman This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink */ // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(LED_BUILTIN, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } -
