I have a membrane with 12 buttons
When a button is pressed it sends a signal.
I need to:
-build a circuit to transform these signals into characters (0to9 and #,*)
-upon pressing '#' or after a lenght of time that can be set, have the numbers stored in memory with a time stamp
-access to the memroy by a wireless connection if it's possible
-a program to read the memory
and I need the design to be small and tiny
we are using a pulldown, a [url removed, login to view] resistance with a crystal of 4MgHz. Then we retreive the pic with 2 capacitors in parrallel of 22 picofarad. Theres a tension of 5v but no current. We are having problem programing the pics since when we test it nothing is stored in the memory.
We are trying to find a solution for this setup or build something else that will accomplish the task:
we need the smallest setup possible using the lowest voltage possible. We need to transform these signals into numbers (0to9 and # and *) sent from the membrane and store them.
Everything should be on the same tiny circuit
**We have made a final design(hopefully) to our circuit, we only need the programation for the ATMEGA8L AND A PROGRAM TO INSTALL ON WINDOWS TO COMUNICATE WITH THE CIRCUIT WHEN HE'S CONNECTED TO THE COMPUTER.**
