```

读取 ID 结果为 0, 断开 LCD 排线后结果也为 0。

硬件连接检查：
1. CS    ---> P21
2. MISO  ---> P0
3. SCLK  ---> P22
4. MOSI  ---> P20
5. DC    ---> P3

BL602 引脚功能检查：

![输入图片说明](../imageawef.png)

错误：
 - P22 不能做 SCLK

修改引脚分配：

## 2022年12月27日

修改引脚后，使用安信可开发板，连杜邦线可以点亮 LCD，使用自制 PCB 连杜邦线点不亮。

可以用安信可开发板，连杜邦线读电容触摸，存在的问题
 - y轴在超过半屏时，数据会跳变，然后增长方向会相反
 - 长时间后（5分钟左右），会停止读数据

最新的 IOTable
