《安富莱嵌入式周报》第255期：2022.02.28--2022.03.06，相位补偿，万用表&LCR表设计最新进展，250M示波器转接板，浮点库Qfplib

---

1、FatFS作者ChaN老师新作

一如既往的漆包线风，手艺依旧很棒，这次设计的电源板，做成了双面板，并且做了铺铜设计，先铺绝缘层再铺铜皮。正面的器件需要接地就戳破绝缘层焊接到铜皮。

正反面设计：

 

 原理图：

 

 

2、用于M0和M3的浮点库Qfplib

这个库非常不错，对于不带硬件浮点的M0和M3系列芯片来说，值得一用，特别是做了浮点三角函数，做了高度优化。

Qfplib: a family of floating-point libraries for ARM Cortex-M cores

 与MDK和IAR带的C库比较，速度优势超级明显。

 

3、通过相位补偿将8通道非同步ADC采集设计成同步采集

这个是TI提供的一个参考设计案例，非常有参考价值，使用相位补偿算法补偿多路复用ADC引入的额外相位延迟，从而产生与同步采样ADC等效的效果。

5、上百个非常棒的技术博客

这个是发布在hacker news的一篇帖子，很多网友进行了推荐留言，大家可以看看有没有自己喜欢的。

6、所有STM32系列DAC最高采样率比较

以STM32H7为例，实际测试过12MHz触发DAC+DMA也可以正常工作，但是随着程序的复杂会影响其它外设正常运行，这点在使用中要注意。

8、万用表，LCR表最新进展

上次更新进展是2021-08-23，那个时候电压表、电流表和LCR表基本功能已调试完成，但是在温飘、精度、噪声、功耗方面进一步优化。

这次更新已经是第5版硬件设计了：

（1）外壳改为铝合金外壳

（2）2张板子，取消屏板

 最早版本时的效果：

 

 

9、H7-TOOL本周进展

H7-TOOL详细介绍：https://www.armbbs.cn/forum.php?mod=viewthread&tid=89934

1、提升 H7-TOOL示波器硬件指标, 设计250M采样率转接板

已经投板了，等回来了，开始设计软件支持。采用树莓派单片机RP2040直接驱方案，使用可编程IO可以做到250MHz的翻转速度。

【结构】

（1）大小和BNC头转接板差不多大，分2个板子，上下安装亚克力保护板

（2）上面的板子是引脚排针和BNC插座

（3）下面的板子是示波器核心部分

 

【主要指标】

（1）单通道250Msps，双通道125Msps

（2）模拟带宽 > 50M

（3）电压量程: ±40V ±10V ±2.5V ±1V ±250mV ±65mV ±16mV

（4）硬件触发 CH1或CH2触发源

【硬件方案】

（1）树莓派单片机 RP2040

（2）ADC选AD9288或MXT2088

（3）和TOOL通信方式串口或SPI待定

2、H7-TOOL的10个GPIO输入输出简易控制

TOOL有10个GPIO，D0到D9可供做普通GPIO使用。

 设置方法：

 

3、H7-TOOL高速DAPLINK调试带看门狗的程序会出现打断点后，无法正常暂停，解决办法比较简单，在Option选项冻结看门狗即可

程序使用了看门狗不像低功耗，低功耗会直接调试不正常，而看门狗的话，如果在程序里面打了断点，会出现程序还在正常运行的假象。

现象就是打断点的地方会一闪而过，闪烁过的时间由喂狗溢出时间决定。

解决办法比较简单：

芯片专门设计的功能，就是为了方便用户在低功耗和看门狗模式下载可以继续使用调试。以STM32H7为例，可以在MDK option选项的此处进行设置：

 也可以直接调用API设置：
