We are using Himax driver based 3.2" LCD and connected through EMI  ( External Memory Interface ) with LPC1788
( we are using em Win ). Is there any way to avoid tearing effect?

for other board which is using RGB interface we implemented multi buffering method to overcome this problem.But in EMI there is no V SYNC, So we don't know how to implement multibuffering concept.

if anybody implemented please share the code or suggest steps to implement or if it is not possible, please suggest other methods to avoid tearing effect.
