Hello,
right now i am working on the product of minilogger for communicating with PID card,in which my job is to convert it from c8051f340 to msp430f5438.
i have c code for c8051 & i have done almost it to msp controller. The doubt i found in existing code is with 7segment display in which programmer has added one file named VTEnglish.h. i am using 8 digit display 4 as upper & 4 as lower. Here i am giving snap shots of it.
unsigned char code ASCVs7Seg_codes[] = //As per this SW. Partly STD

0x00, //20H (space) <-- index starts with 0. So subtract 20h first. blank for unresolved CHAR

};
And below is the code of main file where the above code of VTEnglish.h is used,,,
vt_address=0;
disp_menu();
vt_address=1;
disp_menu();
void disp_menu()
{
B2R4 = (vt_address) * 4;
for(B2R5=0;B2R5<4;B2R5++)
{
disp_m4[3-B2R5] = ASCVs7Seg_codes[VTmsg_short[B2R4 + B2R5]-0x20];
}
}
i don't understand wt this code will display .Hoping for the response soon
thank you
