ID:00000000
lcd id: 0
读取 ID 结果为 0, 断开 LCD 排线后结果也为 0。
硬件连接检查：
- CS ---> P21
- MISO ---> P0
- SCLK ---> P22
- MOSI ---> P20
- DC ---> P3
模式检查
BL602 引脚功能检查：
错误：
- P22 不能做 SCLK
修改引脚分配：
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
