bootloader for at89c51rd2 and FLIP

Em Bee over 14 years ago

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.

it's already there

check the datasheed and the trailing letters on your chip some come with serial boot, some with USB boot

Thanks Eric - the advice is much appreciated!

I've seen a lot of tutorials around the web, including ones on this site.

Do you have any that are your favorite?

Thanks...

I refuse to use Arghmel chips because of previous experiences

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?
