2 questions

[Archangel]

Hi Everyone,
I have 2 serial related data questions.
1.How, do I make PIC Basic Pro, interpret a string sent Serially from a P/C or another PIC as a command? Using Hserin and the variable called Char I tried something like this:

While char = value
PortA.1 = 1
wend

Question 2:
I hooked my serial backpack up to my P/C.
The backpack uses the hserin protocol in and the lcdout protocol to output data to the LCD. It is equipped with a max232 to interface with the P/C. When I send data to it from the P/C it prints strings of text on screen in this order, Line 1, line 3, line 2, line 4. it completely ignores the commands $FE, $C0 and so on, rather printing them onscreen as part or the text string, so in many ways this question is related to question 1. When I send the data to it from a PIC it properly formats the screen with the normal LCDOUT commands.
Thank You,
JS

Hi Joe,
What software are you using send the data from the PC to the LCD? If it's a terminal program you need to figure out how to send the ASCII representation of $FE. You can't just type "$FE" because that will send the three characters $,F,E and not the LCD's "command identifier".

If you are using Hyperterminal it MAY work by doing this:
Hold down the left ALT key on you keyboard, then, on the numerical keyboard type 254 and let go of the ALT key. Then do the same but type 192 instead. This should be the same as sending $FE,$C0

If you're using the Serial communicator in MCS look for "Parse Control Characters" in the help file.

Hi Henrik,
I am using something I found SOMEWHERE called serial sender, I was unable to get hyperterminal to work. Thanks, JS

Hi,
I found SerialSender here:
http://www.seetron.com/vfdmnl/mnl.htm

If that is what you got it looks like this is the way to send ASCII:
Try typing <254><192>LCDTest and then hit Send.

Thanks Henrik,
that is the way!

Joe,
Do you have VB5 or any sort of programming language for the PC? If not, I could probably whip you up a simple program this weekend to do those types of things for you with a click instead of all the extra characters, and just for the serial backpack type of thing.
Heck, I may just whip one up for myself anyways...might come in handy...
