18F25K50 ex_usb_hid example

It falls over in pic18_usb.c on

Always post your compiler version!
The version number looks like 4.xxx and can be found in several places:
1) The easiest way to find this is when in Windows you open the menu: Start / PIC-C/Compiler Version
2) In the CCS IDE, top right is a '?' symbol, click this, then select 'About'.
3) In the top of the compiled list file (*.lst), but this requires your program to compile.

CCS maintains many of the chip specific settings in a database and with the many new chips being released they sometimes forget a feature.
When you have a compiler version with IDE (that is, PCWH or PCWHD) then there is in the PICC program files directory a program called chipedit.exe.
Start this program, select your chip model and then from the top menu select 'registers'.

My version 4.141 shows the UFRMH register at the correct address F69. That's why I suspect you have an older version?

I didn't try to compile the example program, but as the example program was created for one of the CCS Demo Boards you will have to make some changes in ex_usb_common.h to fit your hardware configuration.

As another comment, remember that CCS often reports errors in a different place to where they are actually happening....

How are you actually selecting this processor?.
You have to add the section for it, to the ex_usb_common.h, as:

I have the latest version.. Only updated 4 days ago, and I also have v5 ide

I'm not at my work pic right now, but I'll try those things in the morning.

Thank you.

Go back to 4.141, do the changes I outline, and use a working compiler, rather than a beta......

Seriously, I'm going to wait at least a couple of months before I try V5, or until I find a processor not supported by V4. V5 is beta. As a 'beta tester' which is what you are, report the problems to CCS. However given the number of problems with bits of V5 (work out how quickly we are on the fifth release of this), don't expect a quick fix....

Learn a 'mantra' about CCS - They use their customers as beta testers, and don't make this always obvious. So while they were showing v5 as beta on their site, they still were downloading it to people when a standard 'upgrade' was asked for. Always use the older version when 'new' things are launched, unless you must have a feature in the new version, and are happy to be beta testing.

Best Wishes

Still stuck, because I don't have a copy of 4.141. I've asked CCS for it. The last V4 I have is 4.132, and that won't compile.

I also have a tech support query in with CCS since Friday.

I guess all I have to do is wait now.

Thanks.

It compiles now.

While I'm here, has anybody seen this example working on the 25K50?

[oxo]

It compiles and runs now, but won't enumerate. The odd thing is that if I leave the ICD-U64 connected it seems to reset and retry the enumeration every 3 seconds or so. Doesn't do this if I program then disconnect the pod.

The PC does that USB bong on connection, but then says USB device not recognised.

I assume from the fact that we had to make changes to the code that this example has never been run on this chip.

This is now working, thanks to Darren @ CCS.

I'm having the same problem and I didn't want to open a new thread.

My compiler version is 5.001

This can't be that hard to compile the ex_usb_bootloader.c but I failed.

I tried to open and compile ex_usb_bootloader directly from the examples. When I do that I get the "I/O error 103" so i get a copy of ex_usb_bootloader.c and ex_usb_bootloader.h and renamed in a different folder. This time I didn't get 103 error, at least.

I commented out "define USB_HW_CCS_PIC18F4550" and defined new for 18f2455 and also add if defined statement to the .h file with the same settings from 18f4550

[oxo]

You say it compiles now? So what error do you have?

[dsevgor]

i get 100 errors starting with bad sfr name and lot of other things like undefined identifiers etc.

[dsevgor]

I was out of the office sorry for the insufficient reply.

I get 100 errors starting with error 28 line 118 (30,31) expecting an identifier Bad SFR name in pic18_usb.c and lot of expecting a declaration etc.
error 57 expecting a structure/union in usb.c (line 745 (28,29))

I'm sure I miss out something, but couldn't figure it out.

[dsevgor]

and again lots of expenting structure/union and a numeric expression must appear here errors. in usb/c

[oxo]

do you have

#include <18f2455.h>

as the first thing in your code?
