Hello, anyone here is using the Keil compiler? Is it really good? It costs US$ 4.265,19 here in Brazil (8051 Professional Developer's Kit DOS & Windows C51 Compiler, C51 Special Libraries, A51 Assembler, BL51 Banking Linker, RTX-51 Tiny, dScope-51 Simulator Windows & DOS, Monitor-51, mVision Windows, IShell for DOS), but do I need all these tools? It's pretty expensive. I need a powerfull controller for a new project, so I was thinking about the 50MIPS DS89C420. Anyone used it?
