hello , friends
i want to connect a lcd to 8515 with an external memory
i don't have any stk or other board .
and i just simulate this with proteus . and if it work
i create the board similarly
i want to connect lcd to pin .
please help me .
and write the pin that i connect to lcd on 8515
sample :
PA0 - PA7 : D0 - D7
PC6 = RS , PC7 = E
-----------------------------------------
and another question :
must i connect R/w pin to any port ?
1) with bascom a LCD works very well with only 4 lines of data + Rs +E
ex:
Config Lcdmode = Port
Config Lcdpin = Pin , Db4 = Portd.3 , Db5 = PortD.2 , Db6 = PortD.1 , Db7 = PortD.0 , E = Portd.4 , Rs = PortD.5
The last 2 lines must be write in one line !
so you need only 6 ports for the lcd and you can connect them to any port. that is not true for graphic display.
For external memory see the help adding XRAM memory it use a M8515
