A few years ago, I inherited dozens of tubes of 8051 MCUs, specifically the Atmel AT89C51ED2-IM. I know they're old - and clearly tons of much better MCUs exist - but they'd be useful. (Plus, it just feels wrong discarding 100+ good chips.)
Any suggestions what Keil (or other) product to use, which programming gizmo, and possibly a dev board? I'd like to spend as little as possible as this is hobby stuff. 8051 assembler or C is fine.
So far, I've found these but am uncertain if they'll work:
I understand that Arduino's can be used for the programmer / loader, but apparently the "C" type Atmel's I have need a more sophisticated programming device than the "S" types (or is that incorrect?)
Any assistance is greatly appreciated. thanks!
