HID USB on 18F87J50

[pedja089]

Does someone have example for this PIC?
I can't get it to work...

[pedja089]

I searched the whole forum and I only found examples for the PIC18f2550 and 4550.
Does PBP2.60 support USB on 18F87J50?
For the second day of trying all possible examples and with all possible fuse configuration but nothing show in device menager, not even device not recognised...
I bought this development system (http://www.mikroe.com/eng/products/view/303/lv18f-v6-development-system/) from mikroe, thinking that the is a hardware problem, but still nothing...
What are my other options:confused:

[ScaleRobotics]

Should work. I had the 18F67J50 (same family) running CDC. I can try to get an example for it going for HID. By the way, are you using DT_HID260 ? Will try to get something up tonight, or tomorrow morning.

[pedja089]

Yes, I tried that and DT_HID. But nothing happen if cable is plugged or unplugged.
For now, CDC will be good starting point.
I would be very grateful if you could send me CDC example with fuse configuration.
Thank you very much.

[ScaleRobotics]

Well, now I am starting to wonder if I ever had it working on CDC.:( I had a cdc labeled program for it, but what I had does not work. I had a fairly quick time with the 47J53 in CDC as well as HID, but for the 67J50, I can't seem to get either to work, and I have spent a fair amount of time at it.

These were the configs I used for other programs for the 67J50, which pretty much matches Microchip's HID bootloader software.

I will try a few more things, but I wanted to give you a heads up.

[pedja089]

I try cdc from pbp/usb18 and add config, but still nothing...
I use 8MHz crystal, so PPLDIV is 2 is that correct?
What are the chances that the USB module on 3 PIC are broken?

[ScaleRobotics]

Not very high. But (speaking for myself), the chances of the problem being behind the keyboard is pretty high! Just not sure what I could be missing here, doing it two different ways hid, and cdc, and with a USB bootloader, and without. So I am running out of things I can think of to try....

Yes, divide by two would be correct for a 8 mhz.

[pedja089]

I check hardware and recheck, and everything seems ok.
Here is code for cdc from pbp/usb18:


asm

CONFIG STVREN = ON ;stack overflow reset

outloop:
USBService ' Must service USB regularly
USBOut 3, buffer, 14, outloop

Goto idleloop ' Wait for next bufferI spend another day on it, and nothig, rely, nothin on usb...
I really don't know what to do.

[ScaleRobotics]

Well, I am not having any luck over here either. Here is my try at using DT_HID260. I have been successful in getting it running on another J chip, the PIC18F47J53, and looking at the two data sheets, the USB doesnt seem to differ much between these two chips. Except on one the USB data memory is below the buffer descriptors, and the other the USB data memory is above the buffer descriptors. The DEV files seem to point to the USB buffer descriptors (67J50 here): USBMEMORYADDRESS Con $400 ' USB RAM starts here

Here is my code (that does not work)

I try similar thing, but same result.
So is it possible there are some bug in PBP for this PIC family?

[Darrel Taylor]

I'm looking into it too.
Trying to build a board.

But first I have to ask ...
Do you have VDD (3.3V) tied to VUSB?
There's no internal regulator on those chips.

[cncmachineguy]

I can't speak for Pedja's board, But I am pretty sure Walter is using the PIC_LCD3310. If so that DOES show Vusb tied to 3.3V on the schamatic.

[ScaleRobotics]

Thanks!

Yes, I am using Olimex's PIC_LCD3310. Making a board for this family is a little bit of a pain. Darrel, do you want me to send you the Olimex board? I can ship it out tomorrow.

Walter

[Darrel Taylor]

Thanks Walter, that's a nice offer.

But I ordered one from sparkfun. They're only 50 miles away so I should have it by friday, shipped ground.
That's sure easier than building one.

I'm going to try a 26J50 too.
The 87J50 may still be a question mark.

[ScaleRobotics]

Now that's what I call support! Thanks Darrel.

I can vouch for the PIC18F46J50 working with DT_HID260 and PBP3. I have Micochip's mini demo board http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en540669 going. But the 67J50 is elusive for me. Not ruling out my own operator error here, but this operator is running out of ideas ..

[pedja089]

Darrel, thank for support.
I have 3.3V om Vusb... That was first thing to check...
I can send you PIC. Just give me adress.

[Darrel Taylor]

Thanks Pedja,

We have some of those chips, but no boards to put it on.
At least none that would be easy to use.

I think the 67J50 should be good enough since it's in the same family as the 87J50.
We shall see this weekend.

[pedja089]

Dear sir,
Thank you for support.

[Darrel Taylor]

There is something seriously messed up with these chips. And it's all Microchip.

The SFR's from address F40h to F5Fh cannot be accessed with either the MOVFF opcode or indirectly through the FSR's.
They can only be accessed by setting BSR to bank15 and using "banked" opcodes like movf, movwf, bcf etc.

I realize that those SFR's are outside of the ACCESS bank, but that should not affect MOVFF or indirect addressing thru FSR's.

That range of SFR's contains many of the USB modules registers.
Other USB module registers such as UCON USTAT etc that reside in the access bank can be written/read with all 3 methods FSR, MOVFF and banked. So it's not related to the USB module itself.

The USB libraries rely heavily on MOVFF and FSR's.

I have found nothing in the errata or datasheet that mentions this behavior.

To illustrate the issue, here is a program for the Olimex PIC_LCD3310.
It attempts to read several SFR's using all 3 methods and displays the result on the GLCD. With anything in the affected range, only the banked method (GetR on the display) returns a value. Any other SFR's work fine.

Use Up and Down on the joystick to scroll thru the SFR's.

Walter,

My PIC_LCD3310 arrived with a solder bridge between pins 13-14 (D+, RF5).
Sometimes those are intentional, does your have a bridge there too.

I've attached the .hex file for the above program.

[ScaleRobotics]

Weirdness! Will have to check your program out tonight! Thanks Darrel!


No, mine do not have a solder bridge on any of the PIC pins.

Here is a USB HID bootloader, just to make sure your USB portion (still)works.

(Hold joystick in down position at power up to go to bootload mode)

There is something seriously messed up with these chips. And it's all Microchip.

Just went and looked at 1 of mine(I have 2 but must have put the other in a safe place). I see no bridges on the pins anywhere. So Darrel is it safe to assume you will create a workaround for microchips shortcoming? Haha just poking at you. Seems now that you have done the hard part and identified the issue, we need to make an asm routine to talk to those sfr's?

I found this on page 81: But I guess you found that already.


Note: Addresses, F40h through F5Fh, are not
part of the Access Bank, therefore specifying
a BSR should be used to access these
registers.
See, its a feature, not a bug!

I tried to head off that question in my earlier post.
I understand that it's outside of the access bank, but that only affects the "banked" opcodes (movf, movwf, bcf, bsf, iorwf etc). Banked opcodes are the only ones that work in that range on the 67J50.

MOVFF and indirect addressing are not affected by the BSR register.
They use the full address of the register.

From the MOVFF Instruction definition ...

Location of source ‘fs’ can be anywhere
in the 4096-byte data space (000h to
FFFh) and location of destination ‘fd’
can also be anywhere from 000h to
FFFh.

[ScaleRobotics]

I think it is sort of interesting that in both the PIC18F47J53, and the PIC18F46J50 (both known to work with PBP USB) it states:


Note: The SFRs located between EB0h and
F5Fh are not part of the Access Bank.
Either BANKED instructions (using BSR) or
the MOVFF instruction should be used to
access these locations. When programming
in MPLAB® C18, the compiler will
automatically use the appropriate
addressing mode.
However, for the PIC18F67J50, they leave the MOVFF part out of this statement. I wonder if Microchip knows its errata and just didn't add it to the errata list. Or it's just a coincidence.

[Darrel Taylor]

Hmmmm, very interesting indeed.

[pedja089]

I was out of town, now I'm reading posts, and i tested hardware with HID boot loader, and it works.
When can I expect solution?
Is this will be corrected in PBP2.60(which I currently use), or I must upgrade to PBP3?
I really appreciate your efforts.
Thanks to all;)

[mister_e]

There's no good reason to not upgrade to PBP3... forum is free... now say to Melabs & Crownhill you appreciate the forum because it saved your butt a couple of times... get the upgrade ;)

[pedja089]

Yes, you're right, I'll get update;)

[Squibcakes]

I just saw the PBP 3 update too. Everybody - time to open your wallets. Is it really that more stable than PB2?

[mister_e]

Good boy ;)

[mister_e]

Is it really that more stable than PB2?
I can't confirm as of yet, but PBP2 always have been bomb proof to me... Sure enough, the little money invested in the upgrade worth it! 50$/Year? Who cares? less than 1$/Week.

[mackrackit]

I have not seen a version of PBP that was not stable. So far PBP 3.0 has not given me any trouble.

UPGRADE UPGRADE UPGRADE

Maybe the faster folks upgrade the faster they will come out with more bells and whistles.

[ScaleRobotics]

I didn't get very far on the Microchip forum. http://www.microchip.com/forums/tm.aspx?high=&m=596998&mpage=1#597082 They wanted me to try the simulator, and see if the simulator thought that should work or not. I couldn't get far enough in Mplab to find out. Though I am not sure how useful that would be. Does a simulator always sim what it should?

[mister_e]

MPSIM worked with PBP 2.x, will try with PBP3. It has to.

And NO a simulator do not always give you the good results, some are worst than others. As a guideline they are usually decent tool or pure toy, not much.

[Darrel Taylor]

What did you try in MPSIM?

I'm finding that it's reversed in MPSIM.
MOVFF and FSR's work, but banked instructions don't.

[mister_e]

I haven't tried this specific PIC yet. I try to stay away of Sims ;)

[Darrel Taylor]

OK, I'm getting closer.
I think I can make USB work on it.

What a screwy chip.

[tumbleweed]

This is all very interesting. Care to share what you've been able to find out so far?

How is this chip different than the others?

[pedja089]

Maybe is screwy, but it have everything I need for this project, and it's cheep. Thank you;)

[ScaleRobotics]

How is this chip different than the others?

I am sure Darrel will share more.

But one way it is a bit odd, is it shares addresses for SFR's. See: 5.3.5.1 Shared Address SFRs . You have to set the ADSHR bit in the WDTCON register to access the alternate locations.

Yeh, I've seen that "feature" in a number of the J series parts, not just the J50.

It doesn't seem to have anything to do with USB register access, though.

[ScaleRobotics]

Darrel talks about it in post 19 of this thread:


There is something seriously messed up with these chips. And it's all Microchip.

The SFR's from address F40h to F5Fh cannot be accessed with either the MOVFF opcode or indirectly through the FSR's.
They can only be accessed by setting BSR to bank15 and using "banked" opcodes like movf, movwf, bcf etc.

I realize that those SFR's are outside of the ACCESS bank, but that should not affect MOVFF or indirect addressing thru FSR's.

That range of SFR's contains many of the USB modules registers.
Other USB module registers such as UCON USTAT etc that reside in the access bank can be written/read with all 3 methods FSR, MOVFF and banked. So it's not related to the USB module itself.

The USB libraries rely heavily on MOVFF and FSR's.

I have found nothing in the errata or datasheet that mentions this behavior.

And in due time, we will see his work around!

[Darrel Taylor]

WOW, I've been chasing my tail, and apparently for not.

The MPASM that comes with MPLAB 8.73a was generating incorrect opcodes for the banked instructions.
This was making me think things were happening in the chip that should not have been happening.

The actual silicon in the xxJ50's is not the problem.

There is a new version MPLAB 8.76 which has fixed the errors.
Compile your USB programs using the new assembler, and walla, working USB.

There are other chips that will be affected by the problem, and it's not only USB that will be affected, so it is recommended that everyone with PBP 2.60 or later upgrade MPLAB to a version higher than 8.73a.

[pedja089]

I'll give it try tomorrow.
Thanks Darrell

[mister_e]

And obviously, it doesn't seems Microchip have documented that bug... or again, I'm blind

[pedja089]

I just recompile CDC from last attempt and it is working. Now just to try HID with VB6.
You save my butt, again:D

[Darrel Taylor]

I think it's time to retire one of my signature quotes ...

5905

They don't always do what you tell them. :eek:

But I'm definitely keeping this one ... :)

5906

[ScaleRobotics]

I have installed MPLAB8,76. Now I get CDC to work on 2.60C, but I don't get the same file to work with PBP3.

But I am wondering where PBP3 is looking for MPLAB or MPASM? 2.60 allowed you to select the location for PBP, and it also allowed you to show it where the assembler was located. In PBP3 I get this option:

5907

How am I supposed to enter them both? Or are they really supposed to be in the same place??

[Darrel Taylor]

In the Start menu, go to All Programs > PBP3 from melabs > MPASM-MPLAB setup.
It allows you to set the path to MPASM.

[ScaleRobotics]

Thanks Darrel. I had some weird behavior in my computer. PBP3 kept defaulting to MPASMX, no mater how I set it, I'd check back, and it was set to MPASMX. So after removing the Microchip directory, and re-installing MPLAB 8.76, I was able to get PBP to settle on C:\Program Files\Microchip\MPASM Suite . Now CDC and HID work for the 18F67J50 with PBP3.0! Thanks for routing that out for us!

[mister_e]

I have to say I'm glad for Melabs it's not another Microchip twist who had to implement another .HWLIB thing.

Finger crossed for the next USB pic though... BTW, it's about time Microchip release USB3 AND/OR Thunderbolt.

[pedja089]

Darrel,
I try your DT_HID260, and it work on first attempt. It's very simple to use.
But I have question.
If I want to use 64 byte, #define USB_EP0_BUFF_SIZE should be 64, is that correct?
Thanks

[Darrel Taylor]

No, endpoint 0 is for setup and control transfers. You should not change that.
And you should not change anything inside the DT_HID260.pbp file.

Set the report sizes with the defines...
