It's interesting that in fact this is a wrapper around Bdisp_PutDisp_DD_stripe, because on the emulator the latter doesn't work. Does this mean that Bdisp_PutDisp_DD_stripe is coded differently for the emulator, or that the emulator somehow only accepts a DMA operation that fills the whole screen? --Gbl08ma (talk) 05:17, 4 December 2014 (EST)
I have not got around to dumping/looking for the emulator's version of the firmware however I just wrote a simple test and it worked just fine in the emulator. I am using the latest version which uses OS 2.00.
#include <fxcg/display.h>
#include <fxcg/misc.h>
void main(void){
unsigned x=0,y;
for(;;++x){
char tmp[16];
itoa(x,tmp+2);
for(y=1;y<=7;++y)
PrintXY(1,y,tmp,0,0);
Bdisp_PutDisp_DD_stripe(0,215);
}
}
I shall note that if you want to update the entire screen there is no performance benefit for using Bdisp_PutDisp_DD_stripe(0,215) over Bdisp_PutDisp_DD() ProgrammerNerd (talk) 18:34, 4 December 2014 (EST)
