分析
|
|
| adc中做了这样一个小改动，没什么别的作用，这个就是摸鱼怪觉得看起来好看一点。 |
|
|
| 关于按键的判断，这里是因为在调试按键按下后，发现wait等不到CS下降沿信号，从而DOUT未触发。 测试结果如下： |
|
|
| 经过分析，测试文件一直走不到 wait(!ADC_CS_N); 是因为!ADC_CS_N 在 key_press(2);结束之前已经发生了 因此为了测试分析，本次选择使用按键松开为判定 |
|
|
|
|
| 注意：本次测试为了可以 wait(!ADC_CS_N); 按键松开后，不要停留过长时间！ |
|
|
| 此时看以看出，进行了两次正常的读取。 |

| 测试代码符合预期 |
| 板级验证： 拨码开关选取地址 测量短路时，电压为0 测量小电池，电压比较准（手边没万用表，划划水啦~） |
