SN65DSI83正常启动屏幕显示,若CPU将SN65DSI83_EN拉低后,在拉高一直黑屏。如何才能解决这种情况

  • SN65DSI83 DSI 至 FlatLink 桥接器件, 可能,没有问题, 会不会是屏复位后没有初始化
  • 您好,EN引脚相当于reset ,shutdown引脚,再拉高需要重新初始化。
    如果在您的应用中,中途不需要屏幕显示,那么可以按照下面的步骤进行:
    When the system requires to stop outputting video to the display, TI recommends to use the following sequence for the SN65DSI83 device:
    1. ClearthePLL_ENbitto0(CSR0x0D.0).
    2. StopvideostreamingonDSIinputs.
    3. DriveallDSIdatalanestoLP11,butkeeptheDSICLKlanesinHS.
    When the system is ready to restart the video streaming. 1. StartvideostreamingonDSIinputs.
    2. Set the PLL_EN bit to 1 (CSR 0x0D.0).
    3. Waitforminimumof3ms.
    4. Set the SOFT_RESET bit (0x09.0).
