better fit MY needs. I've finished to build an Programmer for CY7C291
and Am27C291 Chips yesterday and it has a simple AtMega644P CPU on it.
This way I have enough RAM to buffer the ROM contents + some extra for
the Program on the device. Could have build it with an FTDI in it, but
what for?
I understand. Even when working with MCUs with native USB support
built-in, I'll dedicate some pins to driving a MAX232 for RS-232
serial interface for debugging, even though it may be feeding a RS232-
to-USB adapter. It's just that 232 is simple and less prone to
coding errors. I suppose that I could go to USB using one of the
FTDI, but it's really a wash.
