SDCC with Cygnal 8051
Started by yong 9 years ago
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?

Cygnal C2 debugger protocol - any specification?
Started by Wojciech Zabolotny 9 years ago
Hi All,
Now, when my Linux C2 programmer (http://www.ise.pw.edu.pl/~wzab/cygnal) works
fine, it would be nice to add debugging support.
However Silabs (formerly Cygnal) does not provide any information
regarding C2 debugging protocol...

Started by Klaus Vestergaard Kragelund 9 years ago
Hi
I'm using a 80C51F302 Cygnal device and I have based the design on what I've
read on the Cygnal site that C2 is the way to go for such a pin-limited
device.
Well in the forum on the site some have commented that the JTAG interface is
vulnerable to noise and 4k7 pull-up/down are recommended...Analog Devices,TI, Cygnal 8051's?

Hi
Analog Devices, TI, Cygnal 8051's
Has Any one used these ?
Did they work out?
Was power consumption as expected?
Any unexpected issues?
My current CPU is letting me down and I am contemplating a change.
A second poor choice would be bad.

...Cygnal/Silabs F12x MAC0, does it work?
Started by Michael Koch 9 years ago
Hi,
can anyone confirm that the MAC0 unit in the Cygnal/Silabs
F12x (x=0..3) does really work? Has anyone ever seen a
non-zero result in the MAC0ACCx registers? I can't get this
thing working. See a screenshot of my small test program at

Hi all,
Is there a good alternative for the cygnal processors?

- Not to expansive development tools

I updated the microcontroller performance comparison data over the weekend

Started by Morten 9 years ago
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
development kit.

What is the cheapest way to develop a USB device? The Cygnal F32x
seems good for its on chip USB controller. But it needs the Keil tools

which is under $500 for 8 bit microcontroller like 8051,PIC, or AVR?
