USB Pics, ICD2, pic basic pro

The _Configs. I looked at them and wasnt exactly sure what to do.. it looks to me like i should change the .inc to match the .pbp? The setting are in fact different. I dont know exactly what they all mean, but I see that the PLL settings are different, as well as most of the others.

Change the .inc to match?

How do i put the code in abox like in other posts?

Thanks,

The 18F4550.inc file was correctly setup for 20mhz. So it wasn't that.

To get mister_e's program to compile... Comment out all the CONFIG lines in the 18F4550.inc file with a semicolon ";". This will let the CONFIG lines in the program take effect.

Stick with the 4mhz osc. I know his program works, so that might help you work out the cable problem.

At the bottom of each page, there's a box that says Posting Rules (scroll down). In that box is a link ... vB code is On.

That link explains all the post formatting commands. The one to put it in a box is [code]...[/code]

HTH,

[vacpress]

many thanks... rewiring the thing and commenting out _configs... will assuredly be back!

thanks for bearing with me... if you ever need solidworks tutoring...

[vacpress]

so, having commented out the .inc _configs, I now get far fewer errors, just 1, besides those irritating depreciation warnings... the error is..

Error[113]: Symbol not previously defined (_FCMEN_OFF_1H)

[Darrel Taylor]

Oh yeah, seen that one before.

For now, just change it to _FCMEM_OFF_1H

If you upgrade MPLAB in the future, you'll need to change it back.
Microchip changed it somewhere along the line.

at any rate, it compiles without errors now, though i will not be surprised if it continues to refuse to work..

a question, i am testing this stuff on 2 laptops. one has usb 2, the other dosent..the one without is an old junker that i am using to save my good laptop the risk, any idea if this could be a problem? i dont suspect so, as it acts the same on both.

i will try the compiled hex..


also, incidently, what is that config flag, and where do i read about them? in the pic basic manual, or in microchip language manual? i come to this stuff from basic stamps and basicX controllers... this is why the assembler pic stuff is foreign to me yet i am trying a fairly difficult task...

when you tried this, did it go smoothly? what were your conditions?


Thanks

[vacpress]

well, it continues to misbehave. i suppose i might make a schematic of what ive got hooked up, i am working on a prefabricated protoboard so i have to trust their datasheet for some information because traces are hard to .. uhh.. trace, under the components.

what is a .COD?

[Darrel Taylor]

At best, a PIC can do "Full Speed" USB. Which is compatible with USB 1.1.
So the old laptop should be fine.

also, incidently, what is that config flag, and where do i read about them?

To find out what they do... look in section 25.1 of the datasheet. Under "Special Features of the CPU" / "Configuration Bits".

To find out what to call them in your program, look at the bottom of the P18F4550.INC file in the same folder as MPASM.
