Re: PLDShell Plus V5.1
I have downloaded V5.0 before, But from somewhere in the internet suggest that only V5.1 support it... I agree we should try it.
Another software that support it : MINC PLDesigner
Searched everywhere on the net, but can't find it.
(Actualy there is one link on...
pldshell plus
Which version? Latest version?
I can't find / select the device...
Some info on the web said that on Version 6.0 max plus support programming only... Full support will be added on later version.
So I tried V10.2, but I can't find FlashLogic family on device selection...
Hi, I have lots of Altera EPX880 (FlashLogic). I bought it relatively cheap (If I can use it) less than $0.2/pcs. This device is obsolete and the only software I know that can be used to design itis PLDShell Plus V5.1.
Anybody know where to download it please...???
I contacted Altera, but...
Thanks for your reply...
The above quote is coming from Redi-volt website.
An investor planning to manufacture low cost power saving circuit for home-based usage. So it should be economical but it should show a decent saving (at least 10%)..
May be I am wrong, but I think Redivolt don't use...
rs422 to rs485
Above is true if you can control both device...
If the device has RS422 interface and you want to control it using PC with RS485 interface. You will got problem...
max 485 pinout
The electrical characteristic is the same. Many vendors sell chips that can be used as RS485/RS422 line drivers.
BUT :
- RS 485 is half duplex (2 wire)
- RS422 is full duplex (4 wire)
Off course you can't connect it directly
75176 hot
Hi mr_ghz,
Thanks for replying..
I just realised that, I put 120 ohm on both 75176 (one for TX, one for RX) I used.. So the load will be 60 ohm when I connect two converter, or loop-it back.. Do you think it's the problem? I'll try to remove one of it...
Is it true that I only need...
I am designing an RS232 - RS422 converter using TI 1 pcs max232 + 2 pcs 75176B. I put 120 ohm load on 75176 output (for termination)...
The circuit is operational, but, is it normal that one 75176 (TX) is getting so hot?
TIA.

Anybody ever use this products? We are interested to use it for some application. Appreciate any comments and hints.
Thank you in Advance...
Atmel has an app note and sample source code...
