HI !
For new personal devellopement ,I built one 4X20 lcd working on RS232 port com .
The device ,work on 19200 baud on com1.
In the site were I take the circuit board, they give me for testing the lcd circuit one soft .
It may explain ,we must start with the number of line ,the chain data ,and must finish with #$ at the end of caracter chain.
For exemple ,if I want to wrote on the line 1 : TEST
I must wrote on the lcd test software : 1 TEST #$
And "TEST" appear on my LCD display .
Here my Profilab circuit ,but nothing appear ...
Can you help me ,or send me one way

Re: Send carater chain in serial port to 4 x20 lcd
Why you didnt connect the send Input??????????????????????
Try this.
This is sending line number and text without any other characters between. If you need a Space between, take a $CONST and change $ADD to 3 Inputs.

Re: Send carater chain in serial port to 4 x20 lcd
IT'S WORKING SO GOOOD !!!!!
I'm so very far to take the good solution !
Yes , I forgotten put the send comand, but it was just one timer generator .
I try use other fonction ,with octet input sending ,or using ascii convertor, but the builder of the hardware and software had created the µc for receive direct character sending ,
You don't know ,this post can help me so good in the continuity of my devellopement !
In past i test I/O hardware for relay or contact input not other .
I'm so very happy !!!!
Thank you very much Kaktus !!!!!
