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, microsys88
