ICSP programming pins...
PostPosted: Sun Nov 28, 2004 10:18 am     Reply with quote

Hi there!
This is my first post as a member here at the CCS forum. I know it's not really a CCS question, but where shall I turn...?
I have got my pic working with the compiler and even got my LCD working nicely. One thing I'm wondering about thoug is ICSP. I have a programmer (Kit150) from http://kitsrus.com/
It has support for ICSP, so on the programmer there is 6 cabels: (GND, VCC, CLK, DAT, LOW, VPP1). Now my question... where shall I connect these cabels for ICSP?
The legs on my poor pic (18F452), is about to break from all the switching between the projectboard and the programmer.
Thanks for any help!!

Hi,

According to the information for the ICD programmers on the CCS website it would be as follows for the target board:

1 MCLR with pull up 47k
2 +5V
3 Ground
4 B7 on the PIC
5 B6 on the PIC
6 optional, B3

It works fo my ICD S40 programmer/debugger and it worked for my earlier Velleman K4048 kit programmer.

Regards,

Klaus

Get yourself an ICD, you'll be glad you did.

I had a kit150 program a 452 without problems (until one of the bc856b's blew, so now I've got a kit3182 instead).

Omit the low pin from the kit150 - you don't need to connect it, and make sure that the pullup on mclr is 47k - 10k or 33k like you see on some designs will prevent mclr getting close enough to 13 volts during programming.

Isn't it annoying that the ICSP pin ordering is different on every pcb, and so you need several kk5 to kk5 cables to use your programmer with different target.

Buying an ICD saves money on a programmer, but the single breakpoint limitation is very frustrasting to use in practice.

If you are use to an emulator, then yeah. But if you are writing, compiling, burning, inserting chip, testing, then it is tons better. Heck, they are less than $200! My ICE2000 was about $2500 not to mention all the processor modules ($500 a pop) and device adapters!

Thanks for replying!
I have got the ICSP to work now, and I think I'll go with that for a while. Though I would love an ICD. =)[/quote]
