USBService is available with the latest version of PBP (2.46)

I have downloaded MPASM 4.01 as directed by MELabs.

When I try to program the PIC4550 from MCS+ I get three errors:

Error[173]c:\progra~1\mecani~1\easyhid\test\picbas~1\test.as m77: Source file path exceeds 62 characters (C:\PROGRAMFILES\MECANIQUE\EASYHID\TEST\PICBASICPR O\USBDESC.ASM)

The other two messages are the same but end in \DESCTEST.ASM and \USB18MEM.ASM

Ideas anyone?

I am using XP pro, PBP 2.46, MCS+ 2.1.08.

MPASM chokes if the file path is too long. Just create a directory like say
C:\PBP\MYUSB and place your USB project files in there to get rid of this error.

Thanks for your reply Bruce.

You have confirmed that the error messages were in fact meaningful and I now understand that a shorter path must be acheived to remain within the parameters of MPASM.

As to the suggested fix, you should remember that you are so far ahead of me in all of this that you are almost over the horizon! I can create a folder as you suggest and maybe even put the correct files into it but in doing so I would be stepping out of the cosseted realm of my IDE.

I want to write my code and then click the compile & program button achieving the result with no manual intervention.

The long path that is defeating MPASM comes from my slavish following of instructions. What I now need are some new instructions on how to modify my setup to automatically yield a path of acceptable length.

Thanks again & regards,

Brian.

Hi Brian,

With EasyHID, on the 4th screen, just edit the location for all files to be deposited in.

I just loaded a complete ready to install software application on our website with all PBP/asm files. I've included the .hex file for folks that may not yet have PBP v2.46 so thay can experiment with it.

You do not need VB. The software is ready to install & run. Just wire up an 18F4550 as shown in the EasyHID schematic, and hookup a pot to RA0 to use it.
