I am currently pulling hair out trying to faultfind my fluffy2 SX programmer.
If anyone has any tips i would greatly appreciate it.
I have a full circuit on veroboard which tests out ok following the authors test proceedure ( 5v, 13.6v, gnd, vdd vpp all tested ok with pic removed) I have also tested the teraterm program which works woth both 2+3 shorted on the lead and with 1 and 10 linked on the PIC)
I get 2 flashes of the green led to indicat 115k com port speed but thats it. Whenever i try to read an sx nothing happens and I have no scope to look at pulses from either com port or data to/from the pic, just a multimeter.
I have trie a 3 pin resonator and 2 pin crystal + caps to gnd, all with the same result.
I AM sure i have the correct com port before you ask.
Any help is much appreciated
try applying power to sx also.
