SDCC with Cygnal 8051
yong - 2004-03-05 10:05:00
Does anyone use the SDCC with Cygnal 8051? I lloked at the SDCC
website and found the SDCC has not been targeted for Cygnal 8051 yet.
But I do find someone in this group said he use the SDCC with Cygnal
8051.
So, can anybody give more info about this?

fine, it would be nice to add debugging support.

Hi,
I have been looking at the Cygnal 8051 (C8051F000). It has 8 Adc, 2 dac, 5
PWM modules plus it has 32k flash ram.
It all looks good to me :)
To get started with the C8051F000 I was thinking of using the C8051F000DK

No, I haven't worked with 8051s but I can't see that Silicon Labs would sell
chips that didn't function. If you've tried several different chips, then maybe
it's the IDE that is the problem. You might want to contact the IDE maker and
