Hello.
**broken link removed**
I am trying to detect and test program pic16f628a .
I am using winpic800.
I tried many things but it all fails.
Please check my schematics and my settings.
First of all, I noticed ,in winpic800 hardware settings,
that when I test, states shuffle around so I tried
changing lpt mode in bios to spp, but it doesn't help.
I am not sure if data,data in or clock should be inverted in settings.
LPT pins 2,3 are not inverted but busy is inverted in LPT hardware.
So please tell me how should I set up inv for data,data in and clock in settings.
I think I read that signals are latched on falling edge of the clock.
Does that mean that clock should be inverted?
This is how I wired pic:
data - pin 13
clock - pin 12
vss - pgm pin 10
vss - pin 5
vdd - pin 14
vpp - pin 4
This is my first time doing this, so don't hold back your reprimands.
Please help.
Many thanks.
