Quoted from Robotworkshop:
I copied over the HEX files for the Bally LCD display and the Bally tester to try those. When I try to program those I also get a verify failure. However if I pick a built in hex file for the LISY35 it can program the larger PIC successfully. So it looks like the programmer itself is assembled correcty. Just an issue with any other hex files I try to add.
It depends on the 'mode' of the hex file for the PIC.
My programmer can only program PICs in 'low voltage mode'.
PIC programs for older LISY versions are in 'high voltage mode' so during the programming the mode changes.
After that the programmer can not access the PIC anymore, hence the verify error.
I will have a look to my 'old versions' and create a list what hex files are working with my programmer and what not.
The current pop bumper driver program is a 'high voltage mode' version.
It is still on my todo list to create a low voltage version ... too many things in parallel, sorry.
