  • MKE04外接无源晶振,起振后用示波器测试EXTAL的波形。

    MKE04外接8M无源晶体,起振后用示波器测试EXTAL的波形,发现对地只有1V。测量其它单片机,这个脚的电压比较高,之所以关注这个电压是因为晶体厂家说无源晶体起振点是1.3V,低了会振不起来。所以想问下这是否正常。除此之外,频率这些都是正常的。 MKE04 is connected to an 8M passive crystal. After the oscillation, test the waveform of EXT...

  • MKE14512VLL16做FFT的速度问题

    芯片选型阶段,用来做电网谐波分析,要求是5V电源,FFT速度快。选了MKE14512VLL16。现在不知道这个芯片做128点、256点的FFT需要多长时间,因为还是选型阶段,手头没有开发板,所以想问下贵司有用M4测试过FFT吗?或者说关于要求计算快的FFT有什么应用方案吗?
