Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello All,

My newest problem, but I think someone will have a quick pointer to sort this.

I have a umite driving i2clcd to a 44780 type display all running fine.
I read data from a TC514 ADC (also i/f by i2c) which produces a 5digit
free-running result for presentation on the display.

The integer can be 0 - 17000.
Using the umite command:-

lcdi2c (4,8,a$)

gives me the result with the most significant digit starting at column 8.
The value will not always stay at 5 significant digits (1,,350,,54,,16544)
so I have to remove or clear the redundant trailing digits when the value
reverts from 5 digits to a lesser number.
Given the display is 'working' it is nontheless unintelligible.

What to do?


rgds, John

I think I am asking for 'right justification' for the char display.
This can be done for the console (PRINT expr) but I don't see how to go about
it for the LCD.

Mr. Microblocks,

Thanks for the reply, it worked right off the ctrl-v !
It's what I love about this place - all the helpful folks and
great answers!

Might I ask where I can find a book/file/reference on all these
obscure instructions?
