Hello forumers
Nobody likes to waste time, so my question is for stopping my plan or continue a project in Excel 2007.

I'm going to use Serial Port Communication for collecting data and visualizate it "live" on screen (single workbook excel sheet).
Trying to implement add-ins (like mscomm.ocx etc) I had no succes, so I found an article ( link ).
I have placed configuration code in macro and I have started to modify, write rest of needed code.

My target screen looks like this

Data from COM comes in following form:
max 6 digit number + CR + LF (i.e. 123876<CR><LF>)

Frequency 20Hz so 20 lines per second.
Speed of COM 9600bps

Beside of reciving data macro will fill cells A29, B29, C29 with calculated values based on data received and timer, for every line received.
Next line received will cause that A30, B30, C30 will be filled.
And so on.
From time to time acording to values single cells will be filled also (D16, D18, D20, D22) but this is not a big deal for macro and computer.
Because of X axis is not automaticaly adjusted from time to time the range of graph will be changed by macro as well.

But what I'm thinking now about is : will it be possible to work? I mean - Will it be fast enough to do the job on live time?
What do You think?
Any opinions, suggestions, advises are welcome.
greetings
