i2c for LCD

[zadah]

Hello

I tried this from Flowcode 4 forum:

http://www.matrixmultimedia.com/mmforum ... =26&t=8037

But it doesnt compile on flowcode 5.

Is there any similar simple solution for Flowcode 5 version ?

I have quite popular "Funduino i2c 20x4 LCD", which I would like to test with flowcode.

Hello,

The file uses customised components, here is a version which should compile correctly in v5.

Thanks Benj

It compiles now OK.

I would like to understand how the modified code works... I noticed that LCD RawSend macro is not calling transmit byte nor enable pulse i2c macros....

I didint understand when i2c transmission occurs inside the LCD macro.

Hi guys!

What chip (I/O Expander) have to use with that flowchart because I tried with MCP8574 and didn't work at all... And another question: RC7 used in the flowchart is for the VDD on LCD?
I use Flowcode V5 Prof. with all the updates.
I need that custom code because I don`t know how to use i2c and I have an project with LCD and the spot for LCD is 1 meter from the 16F887 and in the classic connection (6 wires), from time to time have to reset the pic because the LCD is going crazy.
Thank you!

The I2C code is hidden inside the Enable LCD macro.

Think we used the MCP23017 which may have used to exist under the name of MCP23S17 or something similar.

In that thread with lcd_mcp file is another file for pcf, can you please fix that too to compile in the v5 Flowcode?
