Develop code for Pic XLP microcontroller that can count pulses (max 50hz, 50% duty cycle).
Must provide some kind of software debouncing.
Utilise energy saving techniques to keep micro in low power mode.
inputs: 3 digital inputs; one for pulse counting and two alarm inputs.
If one of the two alarm inputs go high send alert data packet to Alert Recipients mobile no
Update Report Packet:
Every xx hours send current register data along with status of the two digital inputs along with the battery ADC value 0-9 in a compressed packet format, you decide.
Store the following totalized register pulse count data:
hourly pulse count, last 24 hours
daily pulse count, last 14 days
weekly pulse count, last 8 weeks
monthly pulse count, last 12 months.
Develop protocol to:
Read / Write the RTCC clock
Change the freq at which Update Report packet below is sent to recipients mobile as SMS packet.
Read / Write SMS message Centre
Read / Write SMS recipients mobile no
Read / Write SMS Alert recipients mobile no
Read / Write the status of alert digital inputs
Read / Write (clear) Register data for: hourly, daily, weekly and monthly
All packets must have a CRC calculation.
All Command / responses must be made via UART, IRDA or SMS.
IDE / Language of choice is MPLAB C or MikroC
Dear Sir, just a few questions...
1) Why XLP pic since you have to supply power to your comm's gateway...
2) Will you need a voltage translation for connecting your 3 inputs to the pic?
3) What battery source are you planning to use?
4) Do you need a specific package for your pic?
5) I will be using flowcode for your project. If that is a problem for you please ignore my bid.
6) I have done various interfacing projects with sensors. I believe i can complete your project and keep you fully satisfied.
7) In case you need small changes to your project in near future you won't be charged again.
Dear Sir,
I have been developing firmware for Direct Digital Controllers for the past 7 years and I already have tested code modules for pulse accumulators (with software de-bouncing) and communication modules for GSM/GPRS modems.
I can build a prototype for your system using PIC XLP 16-bit Development Board.
Please check my PM also
Best Regards,
