RTL级图示

功能

  • AM调制(固定频率)
  • 数码管动态显示
  • 按键控制更改显示数字(带按键消抖)
  • 四种波形的产生(正弦波/方波/三角波/锯齿波)
  • 可更改频率控制字
  • 带测频模块
  • UART传输/发送(蓝牙/USB均可)

使用指南

按键/开关用途:

RESET(S5):用于模式切换(AM/数字显示/DDS)

S0 ~ S4:上下按键用于更改数值,左右按键改变调节位,中间按键用于波形切换/信号输入切换

左侧拨码开关:用于进入频率控制字更改状态

右侧拨码开关:未分配

AM调制模式

  • 数码管前四位用四个A填充,后四位显示当前波形频率(0569)
  • DAC输出AM调制波形

数显模式

  • 通过S0 ~ S4的上下按键更改当前指定位的数值,左右按键更改指定位,数码管下的LED灯会表明指定位
  • 当串口有数据传入时会暂时显示传入的字符串(8位数字,移位显示),按下按键会切换为学号显示
  • 通过S0 ~ S4的中间按键更改串口输入数据的来源
  • 右侧LED指示了串口数据的来源,左半侧亮灯表明当前接收USB输入,右半侧亮灯表明当前接收蓝牙输入
  • 开发版蓝牙ID: MLT-BT05

DDS模式

  • 通过S0 ~ S4的中间按键更改输出波形,右侧LED会指示当前显示的波形类型
  • 左侧的LED连接了波形信号,在波形输出频率较低时可以看到不同波形的区别
  • 拨动任意一个左侧拨码,进入频率控制字更改模式,更改方式和数显模式类似,这里不再赘述
