Now, we’ll consider one of the previous embedded devices examples to have a closer look at its main components. You should also know that microcontrollers are not the only option out there for embedded solutions/devices, but MCUs are our main interest in this series of tutorials. The computers being embedded in these devices are small microcontrollers (MCUs) or also abbreviated as ♜. We’ve also mentioned numerous examples of embedded devices applications.

3.6 Which MCUs We’ll Be Using And Why? Īs we stated earlier, an embedded system is a computerized system that in most cases will not look like a computer.

(Since it's a completely different compiler from XC8 for PIC, which is "well known" for producing code between "pretty bad" and "completely awful" (depending on version), my "support" for XC8/AVR implies nothing about XC8 for PIC. Os has always been a bit "dodgy" in avr-gcc)

(it does support -O1 and -O2, which produce pretty good code. tmp/foo.c:1:0: warning: Compiler option (Optimize for size) ignored because this feature requires the MPLAB XC8 PRO compilerĬc1: note: Disable the option or visit to purchase a new MPLAB XC compiler license.

The free version of XC8 for AVR *is* avr-gcc, with some of the optimizations disabled. That all the details I persoanlly need but by all means compare XC8 with avr-gcc if you like but my money says avr-gcc wins by a landslideĮdit: correction a workstation license for XC8 Pro is $1,095.00 a dongle version is $1696 USD The no brainer in my world would be to use a free uncrippled avr-gcc for avr's. XC8 "Pro" may do a decent job of effiecent code if you wanting to 1: send them 1600 USD plus yearly maintence or 2: do monthly payments of +- 40 USD a month. What does this have to do with avr support? Well I don't expect MC to not cripple a avr version of XC8 either since they "kindly" offer the "Pro" version of xc8 for avr also.

Others such as Sourceboost faired well compared to xc8 free version. I have compared XC8 with other PIC compilers (free versions) and get 30+% fewer instructions with others, namely cc5x and cx8x as they are the only 2 currently maintained that I'm aware of.

Stick with avr-gcc as long as you canĬomparison with other compilers.
