Post by thread:[PIC]: Problems with Picstart Plus

I am trying to update the 17C44 in my Picstart Plus. It still has the original ver 1.20.00 PIC in it, and I am trying to program a new /JW part with the code supplied in MPLAB V 5.31. The Picstart Plus initially fires up and apparently blank checks the device, but then falls over with a communication error part way through. I suspect the problem is my new dual Pentium Windows 2000 Professional system! Has anyone found a way around these problems? -- http://www.piclist.com#nomail Going offline?

Has anyone found a way around these problems? Install MPLAB temporarily in a slower system (laptop or whatever) and use it to upgrade your Picstart+.

>Install MPLAB temporarily in a slower system (laptop or whatever) and >use it to upgrade your Picstart+. :) Yes I was considering that, it is just a pain to set it up again. I was also wondering if it might be the problem Roman goes on about with capacitors in the power supply. However I have two of these supplies and it happens with both. I opened one up and the capacitors do not look as though they have been extreme heat cycled. Still I guess the trick is to bite the bullet and deal with the other system again :{} But then I was already at the keyboard :) -- http://www.piclist.com#nomail Going offline?

Mainly the 100uF 25v one next to the heatsink. Mine was doing similar things, like starting to program then stopping and giving errors, it's to do with the increase in current when it starts programming I think. -Roman -- http://www.piclist.com#nomail Going offline?

>Still I guess the trick is to bite the bullet and deal with the other system >again :{} Hmm well I have done that on the slower system, but it still has communications problems on my new machine. Do others have these communications problems on fast processors? -- http://www.piclist.com#nomail Going offline?
