Hi

Can anyone post a link or email material about implementations of In-Circuit-Serial-Programming of PIC microcontrollers?

I wish to build the hardware shown here: **broken link removed**, and in addition, find some source code that implements the ICSP protocol - to help me build my version of the programmer's software.

Thanks
 
ICSP doesn't use any special protocol, it's just the normal PIC serial protocol, it's merely a question of designing your hardware to allow programming in circuit - check the Inchworm ICD2 clone details for examples of how it's done.
 
The PICKIT2 supports only a limited number of PICs from within MPLAB. It doesn't support anything above the 16F series or below the 12F (like the 10F series). This is from the MPLAB 7.60 readme for the PICKIT2, the Swordfish compiler wont work with it either.

The good news it doen't support the 16F84 or 16F84A (let it die already) and the very popular 12F629, 16F628 / 628A are missing (the 12F675 and my personal favourite 16F88 are there though)

That list is outdated Bill.

Current (March '07) v1.2 firmware and v2.20 software support tons of devices with programmer support from within MPLAB expected soon;

**broken link removed**

<added>

Oops... Gramo's list is from the link above...
 
Yes, but i think Bill point was about 'within MPLAB' unless life is good and as the list you provided.

That's a nice programmer for the price you pay for. No bad comments on from me... appart it still support the 16F84 :D will this one die one day or not???

Actually the list is new, it's part of the MPLAB 7.60 readme.

The other list is for the PICKit2 software (not MPLAB), does it debug?

No matter what compiler, once you compile your program, simply load the .HEX file it produces with the software for your programmer to program your PIC

As for debugging, no idea as I use Proteus for that
 
Proteus is a software debugger (simulator), the ICD2 is a hardware + firmware debugger.
Proteus is also very expensive.
The 16Fxxx only version is $585 US
All PIC version is $1976 US

Do you think that this is affordable to an average student or hobbiest?
Most don't have your deep pockets, add the multitude of BASIC compilers you seem to accumulate the cost is extremely high.

PS your XBee schematic on your site needs some sort of 5V to 3.3V buffer on the I/O. The XBee is not 5V I/O tolerent.

How many PC's are programmed with assembler? Then why use it with PIC's?
Because PICs are NOT PCs. Your keyboard has a microcontroller, bet it's not programmed in BASIC, same with your LCD monitor. Actually your PCs BIOS is most likely Assembler.

Aye, expensive, not everyone’s cup of tea. But I like the idea of being able to interface between thousands of analogue/digital devices, using any PIC I want and simulating the circuit with an extensive range of virtual debugging tools :eek:

Proteus is not a necessity, but a nice to have. It will save hours of debugging and prototyping development time

Most don't have your deep pockets, add the multitude of BASIC compilers you seem to accumulate the cost is extremely high.

If I knew about Swordfish, and the simplicity/advantage of 18F PIC's, then Proton would not have made it on my site in anyway. Swordfish is $149 US from **broken link removed**

PS your XBee schematic on your site needs some sort of 5V to 3.3V buffer on the I/O. The XBee is not 5V I/O tolerant.

That example was deleted some time ago, and on a side note, perhaps just use an 18LFxxxx PIC as they are compatible from ~2.7V to ~5.5V. That way you can use the single reg, and no buffering required.

Your keyboard has a microcontroller, bet it's not programmed in BASIC, same with your LCD monitor. Actually your PCs BIOS is most likely Assembler.

I have no idea what they used to program the micro's in them, but it quite possible that a higher language was used to accommodate for the integrated complexity of some devices

Assembly is such a steep learning curve to many people as their exposure (which is sometimes very limited) to programming. PIC Basic allows a modular structured approach, away from bit crunching the simplest of tasks.

If the hobbyist wants to debug their project with some sort of ICD, as discussed in the past, they can simply use the .asm produced by the compiler, and whatever debugging software they want.

Well it certainly won't be BASIC, it will almost certainly be assembler, but there's a possibility that it could be C? - although if it was C, I would have expected to see improved assembler BIOS's for PC's available.
 
The Basic/C discussion has been raised several times on different forums in the past, and for micro computers, there's no structural difference or language specific advantage. It comes down to the compiler and how efficient/what methods it uses

There is however usually around 2:1 support for Basic:C

Take a look at the mikroElectronica forum's. Although their software is no where near the same level as Swordfish, its a good indication of the support/popularity for different languages.

Which brings me to my next point. The language is as good as its compiler. Don’t be fooled that every Basic complier is the same product, although many of the simple tasks are the same, some compilers are world's apart.

If you we're to compare them, I'd say (from best to don’t even bother)

Swordfish
.
Proton
.
.
.
.
mikroBasic
.
.
.
.
Any free compilers

That said, there are free version of Swordfish and Proton that limit your use in some way. Swordfish is very leaneate and only limits you to 200 variables, where as Proton is 50 lines of PIC Basic code (unassembled). I have heard that Proton is taking the same path as Swordfish

as long as you get the job done, fast and bug-free, using C, assembler, Pascal, Basic or else doesn't really matter. Basic is more popular because it's easier to learn, english-like written code, etc etc. Often cheaper to buy than any GOOD C compiler. Better? Down to the guy behind the keyboard.

I have nothing against any language, i use all of them.
