Hello everybody!
I'm new here, I'm from Romania and I want to make a remote control with PIC uC for my audio system.
The schematic is simple and its using a 12F629 microcontroller and my needs for my audio amplifier are: one toogle for power on/off and two momentary on for a volume motorized potentiometer thru a H-Bridge motor connection. It will be also, very usefull if the fourth channel will be for mute.
I hope that my poor english is enough for you to understand my needs and, please help me with a hex file that should be doing what I need.
Thank you very much for any help and please, find enclosed the schematic and hex file witch come with schematic and all the four channels are toogle.
PIC12F629 Decoded IR Toggle Switch Circuit
The circuit above illustrates using the IR receiver module along
with a PIC12F629 microcontroller to decode 5 individual IR remote
control keys so the circuit will only toggle one of the 4 outputs
when a particular key is pressed. The 5th key is assigned to the
master clear function that toggles off the 4 outputs. Works with
most hand held IR remote controls that send a single data stream.
However, some remotes send multiple groups of data and only the
first set of 40 bits or less will be recognized. This may result
in the circuit responding to more than one key, or a single key
may control more than one toggle switch. In most cases this problem
can be resolved by selecting an alternate function on the remote
such as (TV, DVD, SAT, AUX, Etc.). circuit power supply is not
critical and should operate on any voltage from 2 to 5 volts DC.
I use a single 3.6 volt recharageable lithium battery such as
found in cell phones.
Setup instructions to program the controller and record the desired keys.
Step 1 - Remove power and install a jumper wire from the input
(pin4)toground.
Step 2 - Turn on 5 volt power to the circuit and the activity
LED will flash 3 times and remain on.
Step 3 - Remove the jumper from pin 4 and the activity LED should
flash three more times and remain on.
Step 4 - Press the desired keys in sequence to record the keys.
The first key must be pressed twice to allow the program
to establish the timing on the first press. So to program
keys 1 to 5 you would press 1,1,2,3,4,5. At each keypress,
the indicator should flash 3 times and remain on.
Step 5 - At this point, the indicator light should be out and
you can test each key to verify it toggles the correct
output. The data is stored in no-volitile EEPROM so
when the circuit is re-booted without the jumper it
should be ready to use with the existing programed data.
For test purposes, you may want to install LEDs and resistors
on the 4 outputs to verify correct operation.
