It"s possible add support National LM75 (read temperature and state overtemperature output pin) ?. The LM75 is standard sensor pc motherboards.

VP-280 GAL Issue - Crashes Reply  

I am trying to program a Lattice GAL16V8 or a GAL16V8A chip with my VP-280 on software version 4.3.4. When I hit Program it gets 10% into the programming and then the application and the burner crash. I have to manually kill the program process and reboot the burner. I used to be able to burn PALs using an earlier version of the program but I think the latest has a bug.

Can you confirm, and let me know where I could get an older version of the burner application from?

Check sum Reply  
Nam Nguyen
Hi, maybe just a dumb question, but hope you guy can help a selftaught newbie. When I load a new file into buffer, I noted the checksum; then when I programmed into the device, VP290 said OK, but when I verify it said "FAIL". Also, when I read the device, the checksum is different. What did I do wrong ? could it be the device faulty ?
Any help would be appreciated.

Last post : Re:VP990, verify DS1287 Reply: myx1
Uaually this series of chips like DSxxx or M48xxx are Real Time Clock plus RAM,with lithium energy source.
After AutoPrgoram is ok,read or verify again may cause the RAM data  change.Cancel the Insertion Test is just avoided this situation.
So when Prgoram ok,do not chick others.use it on board.Check the board work or not.
But it must be sure the source files are right.Read from chip can not be reliable.

That time it was able to connect, the programmer can only read from the chip but failed to write. I am setting the chip model correctly, because that"s what I use in VP-20.
