CCS ICD USB OR SERIAL one ? |

Hi,
1- I'm planning at buying the CCS ICD, but I'm a little confused. On CCS siye, the comparison between ICD2 from Microchip, ICD(RS232) and ICD(USB) shows that USB version is slower than RS232 one
Quote: |
PIC16F877A
MPLAB USB ICD-2 1.36 seconds
PCW serial ICD-S40 (40Mhz) 0.16 seconds
PCW USB ICD-U40 0.24 seconds
|
is it correct ? if yes can we buy RS232 version ?
2- When we use CCS ICD from PCWH IDE, can we set lot of breakpoints or only one breakpoint ?

There's a limited number of breakpoints available. PICs that were released more than about 1.5 years ago have only one breakpoint. More recent PICs have 4 break points. (Please correct me, if I'm wrong.) |

I've used all three and frankly, I find myself going back to use the ICD2 from Microchip. Since I use MPLAB as my editor/environment and their debugger SW only works with the ICD2 (at least for me) I tend to use the ICD2. My current ICD2 is of the earlier generation with the FX2 USB chip. I understand the newer ICD2s are using USB enabled PICs inside.
Frankly, the programming time difference, and it never seemed that much different, is inconsequential to me. I am more interested in a seamless workflow.
For a production environment, I wouldn't use any of these three programmers as they do not have the ability to verify and different Vcc/Vdd levels (assuming the programmer is powering the circuit).
And none of the three are terribly well protected from the sort of screwups that can happen during initial developement. _________________ Rob Young
