Hi team,

Customer use DS941 paired with two DS948 for driving two display panels. and they want to use DS941 for GPIO input and two DS948 for GPIO remote output respectively. but how to configure for this? and what is the corresponding relationship between these GPIOs? For example, for the DS948 linked with TX Port0 of DS941, if GPIO0 is configured as remote output, what's the corresponding input GPIOs pin of DS941? and for the DS948 linked with TX Port1 of DS941, if GPIO0 is configured as remote output, what's the corresponding input GPIOs pin of DS941?

thanks!

Hi Terry,

Here is the configuration.

Write( 941, 0x1E, 0x01)
Write( 941, 0x0D,0x03)
Write( 941, 0x1E, 0x02)
Write( 941, 0x0D,0x03)
Write( 948_port0, 0x34, 0x01)
Write(948_port0, 0x1D,0x05)
Write(948_port1, 0x34, 0x01)
Write(948_port1, 0x1D,0x05)
