24Cxx PIC 16C84 Combiprogrammer for the Henk Schaer,David Tait and
LudiPipo interface
----------------------------------------------------------------------------
interface connections
----------------------
you can use the HS or DT printerport interface without any modifycations.
the only thing you have to do is to connect a 8 pin DIL socket.
you have to make the following connections:
1 ,2 ,3 ,4 and 7 to ground.
5 to 16C84 pin 13(RB7), 6 to 16C84 pin 12(RB6) and 8 to 16C84 14(VDD)
Use
---
command line arguments:
H2:Henk Schaer lpt2
D1/D2:David Tait 07 lpt1/lpt2
L1..L4:LudiPipo COM1..COM4
most of the program should be obvious (I hope).
HEX files can only be of the Intel HEX8M type.To load a HEX file first
select the device type ,then load the file.
HEX files must have the *.hex extension,binairy files must have the
*.bin extension.These files should be in the same directory as the
programmer.
the buffer can be saved as a binairy file,the *.bin extension is added
automatically.
LudiPipo
--------
support for the LudiPipo interface has been added in this version.
this interface is very simple and works without an external power
supply.so it's easy and cheap to build.
but this system won't work on all machines:in some cases the
programming voltage becomes too low.
it's a pity we don't hear much from 'Der Ludi' any more!
error messages
--------------
'error' during reading or programming:wrong device,device not properly
connected,program interface not connected,power supply not connected,
HEX file with illegal data(16C84).
'reload HEX file':HEX file loaded in wrong mode,first
select the device type ,then load the file.
