Hi
i have gone through the Can eXAMP-LES . There they are sending data from different mailboxes but are not sending data from a single mailboxes changing the data each time .
In my program each time I need to update " Mode " value for my SLAVe device to Change its display . Following master .
In timer interrupt of 2.5 ms
" Mode " variable value is updated every 2.5ms
------ Updating slave Device --------------------------------------
ECanaMboxes.MBOX25.MDL.byte.BYTE0 = mode ;
// Sendind data
ECanaShadow.CANTRS.all = 0;
ECanaShadow.CANTRS.bit.TRS25 = 1;
ECanaRegs.CANTRS.all = ECanaShadow.CANTRS.all;
//------------------------------------------------------------------------------
do
{
ECanaShadow.CANTA.all = ECanaRegs.CANTA.all;
} while(ECanaShadow.CANTA.bit.TA25 == 0 );
ECanaShadow.CANTA.all = 0;
ECanaShadow.CANTA.bit.TA25 = 1;
ECanaRegs.CANTA.all = ECanaShadow.CANTA.all;
____________________________________________________________
The problem is the changed value is getting updated only once in the mail box .In the sense MDL register Freezes after this updatiuon at the starting ..
