Thanks for the response,also sorry for the fast typing.

The Pic = 16F648.

The program will light a full color led on ports RB4, RB5, RB6.
Programm runs on internal clock 4Mhz.
The show is great, only a little bit to fast (very fast!)

I want to change the delay.

Indeed, Making port Ra5 LOW the programm stops.

But I want to change the delay.
therefor I have to erase and load the new programm.

The only problem is that I use the Wisp, and it's using also RB4 and RB6.

When I want to erase the program I've got the next error:

Error:
I/O operation timed out.

I used Bumble bee, becouse I coudn't get it xwisp or Wisp working on XP.
Asked wouter 2 times for help before, but he didn't respond.

So my question:
How can I erase a programm with wisp628 hardware while
a progamm is running on 2 ports with be used by the Wisp628 AND running
programm.

Dutch:
Ik kan een programma niet erasen als de poorten gebruikt worden door het
programma (als output).
Wisp628 maakt ook gebruik van deze poorten (als input).
Ik krijg steeds een I/O error.

Als ik het programma kan stoppen zonder MCLR te gebruiken, dan hoop ik dat
ik dan geholpen ben.
16F648 draait op internal clock, dus hier is ook weinig mee te doen denk ik.


Thanks,

Marcel

Hi Marcel,

There doesn't seem to be a 16f64 on the Microchip website
Do you mean the 16f84?

If this is the case all you need to do is stop the oscilator to
stop the device from running.
