Hi all,
I'm trying to make an web application using Klone. I'm using the i2c protocol
and it seems to work however i have some trouble with klone.
First thing, i've made an index.kl1 with some submit buttons and try to read it
out in status.kl1 this workt but when i use some c code the file does not
continue and i get an "Page can not be displayed" error while the command is
correctly sent. below my code is shown it would most likely have some newbee
ways of getting thinks to work but usealy i get thinks to work ;) i've red that
placing response_redirect(response, "index.kl1") woulda work but unfortunately
no uni formal happiness on that part......
Another guestion, i've red on the klone webpage that everything between <%!%>
is like placing your code you've usealy but above the main part like globals
and functions however when i try to put the int I2C_Open(void) and void
I2C_Close(void) i get error meassages??
can somebody help me further.....???
