Using AJAX to write to PHP - then parse PHP

pthartmann

Using Javascript, specifically jQuery and AJAX commands, I would like to write to a PHP file stored on the SD card.

Then, if possible, I would like to parse the PHP file in order to have discrete control within the Propeller.

Last but not least, I would like to also send data(in real time) from the Propeller to the Webpage - I'm not sure if the aforementioned process could work in reverse --> Propeller writes to PHP and then refreshed on the Webpage.

Approaches I would like to stay away from are, IFRAME and traditional GET/POST/REFRESH techniques that reload the entire Webpage.

My latest inspiration comes from this website: LINK

I suppose achieving this would provide anyone the means to send real-time-data to and from the µC and Webpage in an efficient manor. Furthermore this would provide the basis for a quality control system for any automated system. -I have attached initial code. This code has buttons using javascript and other elements from contributors here on the forum.

So first change, it seems unnecessary to implement a PHP file. I could be wrong, but it seems writing to a .TXT file is a more straightforward approach, on both the web side and the Propeller side.

I am working with the following code:

and for writing SPIN code to access the SD card I am referencing the following:

I'll still have to parse the .txt and I'm also having trouble with actually pointing to the .txt, though that should be an easier task.
