How do we flag a record as processed in EasyHID?
Hi,
I can send 30 bytes of data from the PC down to the PIC. The problem is that the logic as it is keeps processing DoUSBIn. I get my first 'good' 30 bytes, but then it keeps on trucking and keeps getting garbage.
Do we have a flag available that we can set to indicate RECORD PROCESSED so that DoUSBIn can just sit there and wait like it did at the beginning?

Not as dumb as yesterday, but stupider than tomorrow!
I can't find a flag in the 18F2550 datasheet that would do what I want.
What about the Byte Count in BDnSTAT and BDnCNT? Has anyone used that yet?

I found something skimming through Jan's book; ACKnowledge is a likely candidate. I'm just not really good at reading books and understanding C.

Hmm, Jan mentions returning a zero length packet as an ACKnowledge. I tried this without success:
ProgramStart:
DoUSBIn:
USBBufferCount = USBBufferSizeRX
USBService
USBIn 1, USBBuffer, USBBufferCount, DoUSBIn
... display USBBuffer data on LCD...
DoACKIn:
USBBufferCount = 0
USBService
USBOUT 1, USBBuffer, USBBufferCount, DoACKIn
goto ProgramStart
END
Darn, this is frustrating. I'm sure it's something real easy too.

Jan says that an acknowledge is part of endpoint handshaking. The 18F2550 datasheet says endpoint handshaking is disabled by default. So I tried enabling it but this register is not defined (not using this syntax anyways):
UEP1.4 = 1

EDIT: Ok, I give up. I emailed Mécanique and hope they'll be able to give me an answer on Monday...

Awe man, I'm so embarassed, I've been chasing my own tail all weekend on this problem. I'm an idiot...
It was my VB routine all along that sent more than one transaction. I misunderstood the comment in the EasyHID generated code that said to "make sure to pass the whole array" when we write to the PIC.
So I did, I had one write for each and every element, the PIC was just doing its job and reading everything the PC was sending.

LMAO! maudit francais
Now i'm sure you'll never ever made the same mistake

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