PIC vs AVR Which Microcontroller to select for your Application

 

 

Advanced Interfaces

In phrases of superior interfaces, then the PIC is absolutely the choice because it has got their act with advanced features along with USB, CAN and Ethernet which isn't the case in AVR. However you could use outside chips, consisting of FTDI USB to serial chips, Microchip Ethernet controllers or Philips CAN chips.  hollyhealthfitness

 

Development Environment

Other than this there are vital functions which makes both the microcontroller extraordinary from every other. The ease of development environment may be very important. Below are a few crucial parameters in order to explain the convenience of development surroundings:

 

Development IDE

C Compilers

Assemblers

Development IDE:

Both PIC and AVR comes with their personal improvement IDEs. PIC development is carried out on MPLAB X, which is known to be the strong and simple IDE compare to AVR’s Atmel Studio7 that's of large 750MB length and is a piece clunky with extra upload-on features which makes it difficult and complex for amateur digital hobbyists.

The PIC may be programmed via the microchip tools PicKit3 and MPLAB X. The AVR is programmed via the use of gear inclusive of JTAGICE and AtmelStudio7. However the customers are switching to the older versions of AVR Studio which include four.18 with service pack3 as it runs a lot quicker and has primary capabilities for development.

The conclusion is the PIC MPLAB X is a chunk faster and consumer friendly than AtmelStudio7.

C Compilers:

Both PIC and AVR comes XC8 and WINAVR C Compilers respectively. The PIC has bought out Hi-tech and feature released their own compiler XC8. This is absolutely incorporated into MPLAB X and functions well. But WINAVR is ANSI C primarily based on GCC compiler which makes it clean to port code and use fashionable libraries. The free 4KB confined model of IAR C Compiler gives a flavour of professional compilers that charges tons. Since the AVR is designed for C inside the beginning, the code output is small and fast.

The PIC has many functions that make it nicely in comparison to AVR however it’s code will become larger because of the shape of the PIC. The paid version are available with greater optimisation however the unfastened version isn't always properly optimised.

The conclusion is that WINAVR is ideal and fast in phrases of compilers than PIC XC8.

 

Assemblers:

With three sixteen-bit pointer registers that simplify addressing and word operations, the AVR assembly language is very smooth with masses of commands and the capability to use all 32 registers as accumulator. Whereas PIC assembler is not that nicely with the whole thing compelled to operate thru the accumulator, forces to apply financial institution switching all of the time to get entry to all of the Special Function Registers. Though MPLAB includes macros to simplify bank switching however it’s tedious and time eating.

Also the lack of department instructions, simply bypass and GOTO, which forces into convoluted structures and a bit complicated code. The PIC collection has a few microcontroller collection a whole lot quicker however again restricted to at least one accumulator.

Conclusion is that, despite the fact that a number of PIC microcontrollers are faster but AVR is better to work on in phrases of assemblers.

Price and Availability

Talking in terms of the fee, then each PIC and AVR are much comparable. Both are available in commonly same rate. In phrases of availability then the PIC has controlled to deliver the goods in stipulated time comparison to the AVR as Microchip always had policy of quick lead times. Atmel had a few difficult instances as their huge product range approach AVRs are small a part of their commercial enterprise, so different markets can take precedence over AVRs for production capacity. So it's miles really useful to apply PIC in terms of delivery schedules while AVR can be vital for manufacturing. Microchip components have a tendency to be more effortlessly available specially in small portions.

Other Features

Both PIC and AVR are available in type of programs. The PIC rolls out greater versions than AVR. This model roll-out will have pros and cons depending upon the packages like more versions create confusion in selecting the right version but on the same time it affords better flexibility. Latest model of both PIC and AVR are very low-powered and perform in form of voltage range. PIC clocks and timers are greater correct but in phrases of velocity the PIC and AVR could be very a good deal identical.

Atmel Studio 7 has brought Production ELF Files, which incorporates EEPROM, Flash and fuse data in a single report. Whereas AVR has incorporated fuse facts into their hex record format so fuse can be set in code. This allows the transfer of assignment to manufacturing less complicated for PIC.

Conclusion

PIC and AVR both are splendid low-value gadgets which aren't handiest be used in industries however also a famous choice amongst students and hobbyists. Both are extensively used and feature precise networks (forums, code examples) with energetic on-line presence. Both have right network reach and assist and both are to be had in huge sizes and shape thing with middle unbiased peripherals. Microchip have occupied over Atmel and now takes care each AVR and PIC. At the quit, it's far nicely understood that studying microcontroller is like gaining knowledge of programming languages, as learning any other could be an awful lot simpler once you have got learnt 1.

It is irrespective to say that whoever wins, however in almost all branch of engineering, there is no word consisting of “exceptional” while the “Most Appropriate for Application” is well suitable word. It all relies upon on the necessities of a selected product, development technique and manufacturing system. So depending on assignment, it is easy to choose properly desirable microcontroller out of PIC and AVR.
