'[PIC]: Allowable ICD length'

Hello Anthony & PIC.ers,

My workshop pc is in a more-or-less fixed position, while the 16f877
target is a machine sitting outside under a car-port & weighs 250kg.
Definitely not mobile, that one.

I started by making a twp comms extension cable between the ICD and
16f877 header extension of  10.4 metres, knowing it was much longer
than I really needed.  It performed poorly, with many hang-ups, GPFs
etc., and was generally painful.
After halving the length to 5.2m it worked perfectly & I was still
*just* able to string it out to the target.

Hope this helps, as un-scientific as it is....

best regards,   John


PS  For the SI-challenged,          5.2 metres  =  17 foot and a wee bit.

Isn«t it better to use long RS232 cable between PC and ICD instead?
