Os has always been a bit "dodgy" in avr-gcc) Design a traffic light controller in 2 directions perpendicular to each other with 3 light phases: - Go straight direction 1 - Go straight direction 2 - Turn left to direction 1. (it does support -O1 and -O2, which produce pretty good code. PROGRAMING TRAFFIC LIGHT - PIC 16f877a Using Mplab XC8 Can anyone help me.

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.
