Easy HID Command -Response application

[ptig185]

Thanks,
I'll try your code out. though I'm at Rev. 2.5 I just ordered an upgrade to the Latest PBPro.
I generated a Feature report using HIDMaker with a 64byte array (similar to what I've been using all along) and I'm getting about 21 msecs on this PC for each pass through the "Timer1_Tic" Handler. This is nearly stock HIDMaker C# and PBasic Code except I've added a Stopwatch from System.Diagnostics to capture the milliseconds to execute the SendReports then ReadReports.

Elsewhere in my older code from EasyHID, I've moved the USBSERVICE inside my timer interrupt routine and that has improved the time to return input reports. So now I currently USBSERVICE at about 1 msec. intervals.

The service routine should work with 2.50.

I've had it all working while embedded into various other programs from 2.47 to 2.60. This time I just put it all in an include file that's specific to your situation. Well, a lot of peoples situations.

You should be aware that USB is handled differently in PBP 2.60.
Programs from earlier versions will have to be modified to work with it.

And since your program is coming from HIDmaker, you'll probably need an upgrade if you've had it awhile. I don't know that for sure because I don't use it, but it only seems logical.

Where should this go?

I cut'n'pasted from the above code section, into microcodestudio, then added this to the top, before the define

' **************************** Added from other demo
buffer	Var	Byte[16]
cnt	Var	Byte
LED	Var	PORTB.0
Define  OSC 48
'****************************************************

high led

Then at the bottom after overusbservice I added the usb in/out and a led flash to show its alive

idleloop:

    low led
    pause 500
    high led
    pause 500

	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:
	
    USBOut 3, buffer, 14, outloop

	Goto idleloop	' Wait for next buffer

usbinit and usbservice was removed from the code of the other demo like it says to.

It looks to me like a worker, but i get compile errors, lots of them

This one

IDLEIF             VAR UIR.4         ; USB Idle Interrupt Flag
<

gives me a bad datatype (first of a few)

and this one

    UIE = $7F                    ; enable USB interrupts

throws up a syntax error with some more below it


I tried it as

INCLUDE "USB_ASM_Service"

At the top of my little test and MCS opened it as a 2nd page, and threw up the same errors.

Just for completeness thats here

include "USB_ASM_Service.pbp"

Looks like you've been busy while I was sleeping.

PBP 2.46 was missing a few registers in the PIC18EXT.bas file.
You can either add these lines to that file, or place them at the top of your program (before the INCLUDE file).

UIR  VAR BYTE EXT
UIE  VAR BYTE EXT
UEIE VAR BYTE EXT
UEIR VAR BYTE EXT

For the _config depricated warning you can add w = -230 to the 18F2550.inc file ...

        LIST p = 18F2550, r = dec, w = -311, w = -230, f = inhx32

hth,

[f_lez]

thanks that was just the little gem of info i was missing!

And it works!

[f_lez]

Simple code in a loop...

' Main Program Loop
Loop:
 
    USBOut 3, Buffer, Cnt, loopy
loopy:
    porta=170 ' fancy led pattern0
    pause 500
    porta=85  ' fancy led pattern1
    pause 500

    goto loop
end

After about 30 minutes, stops running......

Pic is stable etc had it running 24hrs+ on a simple led flasher. (on same dev board)

any guesses?

[Darrel Taylor]

Well, it's a Total guess but ...

Try adding a USBIN statement to the loop.
If anything comes in, and the SIE doesn't get released, everything locks up (including the PC application).

The reason I say it's a guess is because it requires recieved data.
If you are using HyperTerminal then you would need to type something to have it happen.
