| GLCD driver and DSPIC |

Hello,
I want connect GLCD to dsPic6010A but I don't known how.
At PIC18F I using HDM64GS12.c driver and works ok, but in dsPIC port is 16bit.
For example command
data = input_d(); // Get the data from the display's output register
reads all ports up 8 bit.
Is simple trick to solve this ??
Best regards

It depends on your hardware configuration.
For example, if you have used the lower 8 bits of port D and data is defined as an int8 then no change is required.
If data is defined as int16 and you have used the lower 8 bits of port D then data = input_d() & 0xFF;

Hello, thanks for reply.
Ok i understand this. I write 16bit to 8bit variable so I write 8 LSB.
But when i use this command, I change direction of all pins at port.
So how I can use other pins at this port ?
This situation is also at command
Output_d = data.

Hello,
No one using dsPIC ??.
I think I must change data=input_d to
| Code: |
if(input(PIN_d0)) bit_set(data,0);
else
bit_clear(data,0);
|
etc...
But, I'm think over is this solution is to slow ??
Best regards
