We have used Q24 plus to design and develop a GSM Telemetry solution. Due to severe resource problems we’ve somehow designed this solution in a kind a reverse way. That means, instead using the Q24 plus ARM7 CPU power we’ve used PIC16F877A micro controller to interface (RS-232, RS-485 etc) with the Q24 plus module. We’ve used EEPROM 24C512 for storage instead of using Q24 plus flash memory (I think it’s 1 MB or something which is available). Code written in Assembly.
Now I’ve a Q2686H sample, we would like to go ahead (new features) with GSM/GPRS Telemetry solution. The questions are:
(a) Will it take lot of time for us to develop a proper Design (using Q2686H pin outs, thus eliminating PIC16F877A) - it would be kind of right from scratch almost!
It took us 3-4 months to come out with a Q24 plus based proper design & solution (even though reversed) - design from scratch, schematics, fab, firmware and software application to capture the relayed Telemetry GSM data.
If the Answer for (a) is not advisable to pursue in terms of time & cost, then:
b) Reusability: How to convert this Assemble code into C (Q24 plus to Q2686H; what tools to be used; we used only Mircrochip IDE for the programming with Q24 plus).
©Are there are any Application notes or reference designs based on Q2686H? (which could help me to save time)
Note: Local Wavecom dealer is hopeless in terms of tech support or component supplies! We don’t have good resource to speed up the design and coding. We are in kind of catch-22 situation (in soup) by investing lot of money but still we are not yet there (market ready product).
Please answer my questions. Thank you very much in advance.
