Does someone have example for this PIC?
I can't get it to work...
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 from mikroe, thinking that the is a hardware problem, but still nothing...
What are my other options

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.
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.
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.Code:'DEFINE LOADER_USED 1 'DEFINE RESET_ORG 1000h ' For Microchip USB Bootloader #config CONFIG PLLDIV = 5 ;for 20 mhz chip CONFIG XINST = OFF CONFIG STVREN = ON ;stack overflow reset CONFIG WDTEN = OFF CONFIG CP0 = OFF CONFIG IESO = OFF CONFIG FCMEN = OFF CONFIG CCP2MX = DEFAULT CONFIG WDTPS = 32768 CONFIG CPUDIV = OSC1 ;DIVIDE BY 1 MODE CONFIG FOSC = HSPLL CONFIG MSSPMSK = MSK5 #endconfig DEFINE OSC 48 clear OSCTUNE.6 = 1 ' Enable PLL for 18F87J50 family
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?
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.
I check hardware and recheck, and everything seems ok.
Here is code for cdc from pbp/usb18:
I spend another day on it, and nothig, rely, nothin on usb...Code:asm CONFIG PLLDIV = 2 ;for 8 mhz chip CONFIG XINST = OFF CONFIG STVREN = ON ;stack overflow reset CONFIG WDTEN = OFF CONFIG CP0 = OFF CONFIG IESO = OFF CONFIG FCMEN = OFF CONFIG CCP2MX = DEFAULT CONFIG WDTPS = 32768 CONFIG CPUDIV = OSC1 ;DIVIDE BY 1 MODE CONFIG FOSC = HSPLL CONFIG MSSPMSK = MSK5 endasm Include "cdc_desc.bas" ' Include the HID descriptors Define OSC 48 buffer Var Byte[16] cnt Var Byte OSCTUNE.6 = 1 ' Enable PLL for 18F87J50 family Pause 10 USBInit ' Get USB going ' Wait for USB input idleloop: USBService ' Must service USB regularly cnt = 16 ' Specify input buffer size USBIn 3, buffer, cnt, idleloop ' Message received buffer[0] = "H" buffer[1] = "e" buffer[2] = "l" buffer[3] = "l" buffer[4] = "o" buffer[5] = " " buffer[6] = "W" buffer[7] = "o" buffer[8] = "r" buffer[9] = "l" buffer[10] = "d" buffer[11] = 13 buffer[12] = 10 buffer[13] = 0 outloop: USBService ' Must service USB regularly USBOut 3, buffer, 14, outloop Goto idleloop ' Wait for next buffer
I really don't know what to do.
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?
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.
DT
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.
-Bert
The glass is not half full or half empty, Its twice as big as needed for the job!
http://foamcasualty.com/ - Warbird R/C scratch building with foam!
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
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.
DT
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/id...cName=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 ..
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.
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.
DT
Dear sir,
Thank you for support.
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.

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.

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)

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

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
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.
DT
I think it is sort of interesting that in both the PIC18F47J53, and the PIC18F46J50 (both known to work with PBP USB) it states:
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.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.

Hmmmm, very interesting indeed.

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
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
Steve

Yes, you're right, I'll get update
I just saw the PBP 3 update too. Everybody - time to open your wallets. Is it really that more stable than PB2?
Good boy

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

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

I didn't get very far on the Microchip forum. http://www.microchip.com/forums/tm.a...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?
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.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
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.

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

OK, I'm getting closer.
I think I can make USB work on it.
What a screwy chip.

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?
