Cant get my processing sketch to wait for a response from the arduino
sorry if im getting boring. i promise i will get onto a rock crawler rover thing once i have got some life out of the polargraph...
The code below, does exactly as i want in terms of processing the image, and converting it into a stream of values.
however i want it to
1) wait for an initial "ready" command from the ardunio
2) wait for a "ready" command from the arduino in between each and every number transmission.
the arduino is processing the numbers physically, and therefore takes time.
I have used "300" as my ready command because the sketch is dealing in shades between 0 and 255. I figure it it one less thing to worry about if i dont start chucking ascii in there too.
My "commands" can be 300, 301, 302 etc.
I THINK i have narrowed down the lines which need attention to lines 17 and 33. I pressume i need a "serial Event" void in there? but i am dont know what to do with it. All the tutorials i have read and watched (of which there are many) do different things with it, none of which i understand properly. I presume what is required here depends on the context?
