t113 mipi点不亮

[zzz555]

用的是800x1280的mipi屏，驱动用的是tft08006，用示波器测信号，发现数据线都有正常信号，时钟线却没有正常信号，用打印信息看初始化代码，也有正常使能时钟，请问这到底是哪里的问题？

@zzz555 The clock signal may be operating at a speed outside the bandwidth of your oscilloscope. Check the Hz setting of your clock, and ensure it is less than the bandwidth of the oscilloscope (likely 100 MHz).

If it is higher, then the signal will be attenuated. Configure the scope to be AC-coupled and try increasing the scope gain to see a faint signal.
