WiDSO

简介

通过Wi-Fi/USB显示和控制的数字示波器(DSO)/逻辑分析仪(LA)/信号发生器(DDS)等。
由核心板(WiDSC)和扩展板两部分组成,最多可同时搭载两块扩展板。

核心板

  • 通信接口:Wi-Fi b/g/n,USB FS,UART
  • 扩展接口:两路,每路提供12个高速IO和4个ADC/PWM/SPI复用IO
  • 存储空间:512k字节@16bits位宽
  • 数据速率:采样/输出带宽之和最大100M字节/秒
  • 调试方式:内建USB-Blaster和CDC串口,支持U盘方式升级
  • 硬件组成:EPM240T100+IS61LV25616+STM32F103C8+ESP8266

DSO扩展板(计划中)

  • 通道数:1CH(8位)
  • 采样率:100Mps Max
  • 模拟带宽:>20MHz
  • 输入幅度:+-4V(x1)/+-40V(x10) Max
  • 触发方式:上升沿/下降沿,手动/单次/自动,支持触发信号输入/输出
  • 硬件组成:ADC80100/AD9283-100,其余待定

LA扩展板(计划中)

  • 通道数:8CH
  • 采样率:100Mps Max
  • 输入电平:1.2~5.5V
  • 逻辑触发:上升沿/下降沿/电平(任意通道组合),支持和DSO联合触发

DDS扩展板(计划中)

  • 通道数:1CH(8位)
  • 采样率:100Mps Max
  • 模拟带宽:>20MHz
  • 输出幅度:+-4V Max,可调

TFT扩展板(计划中)
