Dear Justin,

I checked "WINCE700\SUPPORT\APP\DisplaySet" and executed it on WinEC7 platform,

it will not call DisplayConfigureDual.

But I execute DisplaySet that you provide at this link, it will call DisplayConfigureDual.

Can you provide the source code of DisplaySet and mosquito_dual ?

Can secondary display play video ?

I am not familiar with DirectDraw, do you have any tutorial about DirectDraw to draw secondary display.

(http://imxcommunity.org/group/wince/forum/topics/i-mx51-wince600-dual-display-set-di0-as-main-displa...)

Dear Seetharam,

Can you share how to enable dual display in WinEC7 with same content or different content ?

Thx ~

for current WinCE dual display solution, you need use displaySet app in  "WINCE600\SUPPORT\APP\DisplaySet" to enable the secondary display. It will call DisplayConfigureDual().

Please check the attach RM for the details about the dual display.

Thanks Justin for your reply. BSP_ENABLE_SECONDARY_PRIMARY_SURFACE variable is set but what exactly happening is in displaysetmode() function of display.cpp first it is checking for DI0 panel and if its connected then it will not check for DI1.VGA is connected to DI1 and DisplayConfigureDual() function is not at all getting called.Please help me in solving this.

 

Thanks and Regards,

Please check the "DisplayConfigureDual()" in display.cpp  and make sure to set

 #define BSP_ENABLE_SECONDARY_PRIMARY_SURFACE TRUE.
