Blueteeth said:depends on the programmer? what chips you're programming etc... some use the parallel lines of the parallel port (D7-D0) others just bit bang the lines. So if your programmer only uses <8 lines, you may be able to write software to do the same thing with the serial port. Or.....just buy a USB - > parallel port adapter ^^
Nigel Goodwin said:Most such adaptors wouldn't work, due to the completely non-standard way a programmer works.
However said:What I do have is an old Dontronics DT001(www.dontronics.com) (bought quite a while back but got too busy to play with it), it's a programmer and testbed type unit based on
SimmSticks, I have a couple of sticks, one with led's and pushbuttons, one made for use with 16f84a (or similar) and a 40 pin stick.
I thought I would use this to get started and pickup something else (looking at Junebug and Inchworm). Since I had this I thought I would give it a go, but also thought it might be able to run via rs232 with a little mod. I'm still reading a bit about the old/new chips.
Tnx.

Well my new computer has neither, only usbNigel Goodwin said:That's a rather hopeful assessment!
The DT001 is a David Tait type parallel port programmer, it would require considerable changes to use from a serial port.
What computer do you have that has a serial port and no parallel port?.
binzer said:Well my new computer has neither, only usb
I do have an older machine with both and did get it setup for doing the job.
For me something serial would be a bit more portable as the machines I have available at work do not have a parallel port, think they have one serial and many usb. I sometimes have a bit of 'downtime' at work and would get a chance to 'play'.

binzer said:I am trying to use what I have available for right now, (low budget).
I did setup an old dell P3 with XP and Mplab, it does have a parallel, serial,usb, and
hopefully enough memory to use for this. I did buy the Dontronics stuff quite a while back
but just got too busy to play with it, I used to do quite a bit of this type stuff at my old job
(eng tech), my new job is like plug&play except for the diag part so I want to get back into
doing some electronics on the side. I am looking at the Junebug and Inchworm, any others
I should look at?? I am also thinking of trying this under Linux, but Mplab and some of the
other programs seem very good!

There is a little Linux support but the best tools are still using XP. The PICkit2 or Junebug have better Linux support than the ICD2 / Inchworm.
