Amicus IDE is actually a 100% working free version of the powerful Proton PDS compiler. There is a caveat - the compiler will only produce code for the 18F25K20. With that in mind, its probably a good time to get familiar with the 18F25K20.
32K Bytes of Program Memory
255 bytes Data EEPROM
16 MIPS Operation (safe overclocking to 100Mhz!)
Precision 16 MHz Internal Oscillator Block
64 MHz performance available using PLL no external components required
It had a strange following. Particularly for rhe paid version, if you asked questions you were treated with suspicion and hostility. "If you had a paid version, you would not have to ask that question. Pirate!!!!!" Sadly, the same mentallity spead into the forum for the feee version.
