no usb connection and speed change errors
Posted: Thu Dec 11, 2008 10:12 am
Hi all
Ive just purchased flowcode 3 which I am using with the pic micro dev board (version 3)
I have made a small program which flashes led's and the program simulates ok but it is very hit and miss to get the compiled hex to the chip. The program will not compile to chip (i get a no usb connection error) even though the board is powered up via a power supply.
If I assemble to hex and then use PPP to put the prog on the chip I get a working program from the chip but the led sequence is much slower than the simulation.
I am using a 16f818 with internal osc. If I change to RC osc I get a more reliable prog but still not the same simulation speed.
Any ideas folks? maybe I'm missing something simple here?
I have been using the development board for a while with no problems. It seems the problem is interfacing the flowcode with PPP.
Cheers
