Can you explain what the need or purpose is for the analogue inputs ?it needs to be able to accept 2 analogue inputs and give outputs to 7 segment displays, any help would be appreciated.
The circuit for the AT89C2051 could be fairly easily adopted for a PICAXE 28X2, however it is perhaps more a question of exactly what you want and need to be able to progress. That's a muliplexed design with no current limiting resisitors which can be made to work but will prove a challenge to program. Either common-cathode or common-anode displays could be used, it's just a question of sorting out the polarities in software.in A Level systems and Control it does not require you to design them, just to know how they work, build them, produce a viable product from it and program it
Hi the deadline is May/ June this is only the second time i have programmed a PIC circuit and i have read the manual and it shows exactly how to program a timer/ clock, electronics, i have done for 4 years, and i have built infrared guitars, burglar alarms which you can alter the output to, I've also built a monophonic keyboard ... all conventional circuits... PIC is a new thing to me.The circuit for the AT89C2051 could be fairly easily adopted for a PICAXE 28X2, however it is perhaps more a question of exactly what you want and need to be able to progress.

You may however be better off with the four displays driven from separate 4511B or 4026 display drivers as shown in PICAXE Manual 3.
Perhaps some indication of your electronics and programming experience will help, along with an indication of how much time you have to put into the project and when its deadline is.
Look up.could you send me a link to picaxe manual 3 if thats okay?
Before you can do a costing,how much do you think this circuit will approximatley cost , just curious?
