graphical lcd programming with flowcode v3

[Kumaran]

The program when executed gives some errors such as "missing paren, missing semicolon,etc.."
Pls tell the right program to interface monographic Lcd with IC18F4550
using flowcodev3

Ok Please dont triple post when one topic will do !!!!!

There is an example for driving a KS0108 mono graphical LCD from Flowcode available from here.

http://www.matrixmultimedia.com/Flowcode_Components.php

[Kumaran]

i 've downloaded the program ,
but got some errors like /?(failed to generate expression...)
while executing the same ,how to implement the c code in custom component?

[Benj]

Hello

All the instructions on how to do what you require are available on the top of the Beta Components page.

[Kumaran]

could u pls provide the conection details :
data port--?
enable--?
read/write--?
Thanks in advance

[Benj]

Hello

The connections are currently set to the following.

#define MX_DATA_PORT portd //%a
#define MX_DATA_TRIS trisd //%b
#define MX_CONTROL_PORT portc //%c
#define MX_CONTROL_TRIS trisc //%d
#define MX_CS1 0 //%e
#define MX_CS2 1 //%f
#define MX_DAT_INST 2 //%g
#define MX_ENABLE 3 //%h
#define MX_READ_WRITE 4 //%i

Eg the 8 data pins are connected to PortD and the remaining 5 control pins are connected to PortC.

This information is near the top of the custom C code file so you can change to suit your application.

[Kumaran]

i'm not getting the text displayed even after connecting all the ports n pins correctly
can u help me out

[Benj]

Hello

Have you copied the custom code file over the custom code C file in the components directory of Flowcode. You can check this by compiling to C in Flowcode and then seeing if the LCD functions are available.

If you are still having probems then please can you post your Flowcode project file and the C code file that is generated and I will have a look for you.

[Kumaran]

Hi

I have tried the example file that is came along with the download. Please see the project file and C Code generated. today I have recieved the flowcode V4, So I am posting the project created in Flowcode V4.

Thanks

Hello,

I've got one of these displays on my desk so Ill connect it up tomorrow and try out your program to see if I can spot the problem. Not sure if I have a 16F871 to test on but I should have one of the chips from that family.
