'[PIC]: Programming a PIC16F628 using a JDM Program'

is it possible to program a PIC16F628 with a JDM programmer?
in IC-Prog 1.04, i can select the 16F628 for the JDM programmer, and it
indicates that i have to place it in the socket like a 16F84.
but when i try to program the 16F628, it seems to stay empty.
what's wrong?
thanks for your help!

I'm not familiar with this programmer, but possibly RB4 which is the LVP
pin.

Try tying it low with a 10K resistor.

Yeah, like Tony said, RB4 (pin 10 for PDIP & SOIC) needs to be tied
low but iin the JDM design is connected to +5V. With this fixed I
have had success programming PIC16F627's.--

Yes...
It works, but you need to modify the LVP pin in the JDM socket...
I just made a 18 pin dip socket with the LVP pin cut off and soldered to
gnd.

I plug this into the programmer and the pic into it... It works fine...
I tend to use ISCP now and that works every time...

Hello Martin,

yes it's possible, but the schematic should be modified

nothing is wrong with ICProg

we are going to release very soon our PIC-PG2B serial port programmer based
on JDM design which will program 8,18,28,40 pin PICs and 24Cxx EEPROMS.
you can see the schematics at http://www.olimex.com/dev/pic-pg2b-sch.gif and
the board layout at http://www.olimex.com/dev/pic-pg2b.gif
