Tool/software: TI C/C++ Compiler

Excuse me, in Display mode

Adjust <DISP_CL1_CURRENT [11: 0] is to change the total current or independent led string current

    Hi Matt,

    DISP_CL1_CURRENT [11: 0] register sets the maximum current (up to 150mA/string) for every string that is set to display mode - output strings set to display mode will share this register for setting max current. For example if DISP_CL1_CURRENT[11:0] = xFFF and all strings are set to display mode with LED_STRING_CONF[2:0] = 000 register, then all strings will have max current set as 150mA.

    If strings are set to Cluster mode (Independent mode) then there will be different registers for every cluster string to set max current <CLx_CURRENT[7:0]> for those strings and therefore can be controlled independently.

    Best,

    Salome
