I am currently doing a "Microcontroller based Scientific Calculator" which inclueds almost all the functions of a scientific calculator. Work inclueds interfacing keypad and display.
Can you please give me come comments? Is there any good website? Even though I have learned some 8051 but I am still not confident. Is 8051 or PIC better? Thanks for your help!
I cannot help you with websites or code, but there are a calculator in sample designs of Proteus, labcenter.co.uk .
Versions for both 8051 and PIC, but not any graphical versions though.
Both PIC and 8051 seems to be suitable for your application, but if you're programming in assembler PIC instructions are painful for math calculations (it's a RISC MCU)
There's practically no timing requirement... personally, I'd use PIC with a good C Compiler (Hi-Tech?)
