Hello all,
I'm a newbie to 8051 programming. I want to use Atmel's FLIP to program an at89c51rd2 chip using the COM port.
According to the FLIP instructions, there needs to be a bootloader on the chip before programming will work.
How does one get the bootloader onto the chip? Are there any straightforward tutorials on this?
Also, does anyone recommend doing a USB connection rather than using the COM port? The USB schematic looks much simpler than the COM port.
Thanks much.
I refuse to use Arghmel chips because of previous experiences
Erik
Good to know.
I've been looking at a bunch of different 8051-based chips. Do you have any recommendations for chips that would be good for a newbie like me?
Thanks.
there is nothing better than SILabs.
They are (AFIK) the only '51 maker that has on-chip debugging. This allows you to "look under the hood" and see what is going on like nothing else (save $1000 ICEs).
I believe Wiznet has on-chip debug: "
Triscend had it - though they are now long dead.
AFAIK, it's probably fair to say that SiLabs is the only current, main-stream 8051 that has it?
The parametric device database search indicates 215 devices of 8051 architecture with on-chip debug: http://www.keil.com/dd/search_parm.asp
