We had a hardware failure and one of the controllers went kaboom. This controller receive serial data from a piece of software installed in one of the PC's. A co-worker years ago made a controller based on PIC and studied all the data coming from the software. Basically in a PC you type 54 different variables, hit send and the software spits out 225 variables in a format like this:

###### ; ##### ; ### ; ## ; #### ; ##### ; ##### ; #### ; ..... ; # ; ##### ; FIN

##### are 224 random numbers based on the inputs on the PC. These are only numbers (no letters or symbols) and up to 5 numbers per variable (from 0 to 99999)
FIN is to indicate the end of the data transmission.

After reading and copying your Buffering input code from http://mushclient.com/serial, I have the info in the arduino, I only change case '\n' for case ';' and MAX_INPUT to 224.

Now my real problem... If the variables are named:

Variable_1
Variable_2
Variable_3
...
Variable_224

Would you PLEASE explain me how I assign the values to those variables?

Thanks a lot,

Cataina

You'll forgive me if I don't answer this, I hope, as you have cross-posted a very very similar question to the Arduino forum.

Hi Nick,

I'm sorry if I double post. I'm a little desperate and just looking for any possible help.. I looked at the code that zoomkat posted and search on internet and found you, that is why I re-posted here.

Is just embarrassing for me asking many simple questions if I do not really understand many things, that is why I'm looking for similar codes and change what I need.

Again, I apologize and delete this post if you want it.

I'll keep looking for more examples around.

Catalina
