Hello,I have a 8052-Basic sbc and I need help sending 2 and 3 digit variables in my basic program to a parallel connected lcd display. The board and lcd work fine. I can send strings or or single digits ok.Since the lcd only accepts one character at a time, how would one send a 3 digit variable ?This is how I send 1 digit;10 variable = V20 D = V+ 48 : gosub 100100 XBY(X)= RS +1 (bring lcd control line “rs” high)110 XBY(X)= R/W ( select “w” to write )120 XBY(A)= D ( put data on lcd bus )130 XBY(X)= E+1 :XBY(X)=E ( toggle “e” )140 RETURNIf you or someone you know has done this (in 8052-Basic) ,could you show me ? I would be eternally gratefull !Thanks for your time.Sheldon.
i don’t know “Basic” but i did that part in c. here i am writin logic it might help you. this logic use to print any no just depends on type of varialbe “value“(size of variable)
1) take array uchar display[x];
2) let the digit/number to be display on lcd is in varialbe value
3)i=0;
while(value<10)
{
display= value%10;
value = value/10;
i++;
}
display =value;
for(;i>=0;i–)
{
LCD_write(diaplay+48);
}
