problem with I2CWRITE command

[mackrackit]

First off, when you said you looked at the online manual I figured you did not have the printed manual meaning ....
For that I apologize.

Th control is specific to the part being used. I have not used the part you are using so I will need to look at the data sheet when I get back to the shop.

Control does have read/write bits set but normally PBP will changes those for you at compile time.

In th meantime maybe this will help, maybe a work around if PBP does not work well with your part.

Assuming this is the data sheet
http://www.i2c.byvac.com/downloads/B...0DataSheet.pdf

On the other hand, if I use assembler and write the communication from LAB-X1 to ByVac I2C interface to LCD in assembler, I can use without problems all ByVac interface's commands ... $03, $20, $25... etc., while PBP has problems.

From what I see on the above data sheet that would be correct. The display is not setup to have more than one on a bus so it does not use a control bit.

Looks like you will have to use SHIFTOUT. But if you have an ASM routine working just put that into the PBP code.
