Pic 18f Usb

hmm, softwire seems to be vb.net only.

I do not see vb6 support. Any chance you are using an older version of softwire?

Suppose to be available.. look here

Any special hardware being used? How to you hookup the inputs without fear of over voltage?

Well as you want to build a kind of scope, it could be interesting that your input also provide an high impedance. So use a simple OP AMP buffer would do the trick IMHO.

But if don't need any buffer, a simple resistor between PIC and Unit wil do the job. Look at the datasheet, most PIC have two diode as 'Over/Under voltage protection...

Thanks for the 'old' link for 3.1
The regular download button was only showing the newer VB.net version. I do have VB.net because of our University site license (less than $5 per copy) but have a hard time loading up gigabytes of compiler for what should be simple apps. Maybe I should byte the bullet and move up from vb6.

At least I can now try running the app posted earlier in this thread.


I'll read the datasheet for the pic chip. My concern was due to many sites saying never exceed the supply voltage on an input pin.

The scope project would be for hobby based projects. The PIC would monitor a few pins and transmit the data via USB to the PC. The PC would graph the result. If anything already exists that has source and is free, I would check it out. I do not mind starting from scratch. I do not copywrit anything I write, it would be for public consumption.
