My program run on Windows.
For the data is someone have an idea ?
Something like this is correct :
type byte is new short_short_integer;
for byte'size use 8: --8 bits
Reg_1 ,Reg_2,Reg_3 : byte;
for Reg_1'address use To_Address(16#378#);
for Reg_1'address use To_Address(16#379#);
for Reg_1'address use To_Address(16#37A#);
The purpose of all my question is to be able to use a lcd screen (2
lines, 40 caracters) connected on the lpt port.
The connection is like this :
LPT LCD
STROBE 1 -> 6
D0 2 -> 7
D1 3 -> 8
D2 4 -> 9
D3 5 -> 10
D4 6 -> 11
D5 7 -> 12
D6 8 -> 13
D7 9 -> 14
10
11
12
13
14
15
INIT 16 -> 5
SELECT IN 17 -> 4
18
19
