Bus Pirate Development / Re: New Bus Pirate v4 LCD adapters
ian send me the new v4 LCD adapter PCB on Monday so when i arrived on Tuesday i build it up.
I didn't have the right potentiometer for the backlit so i used a slightly large value one but that shouldn't be an issue.

The most work will be the Firmware for the Bus Pirate v4 so it can drive the display directly without the 74HCT595.

Project development, ideas, and suggestions / Re: XT-IDE adapter with CPLD builds
Welcome back again :p

Fram's are a nice piece of technology but for our purposes way overkill, we don't need to write to the eeprom that often.

If its cheaper and it works its nice.

I always remembered that the words stock and Ramtron don't go together well ;) because it took them only half a year to send me a sample of the FM18W08 and Farnell always have low stock of them.

The socket and the PLCC EEPROM have the same footprint so using a socket is optional.

Using flash haves the problem that i cant be used with the current pc software because it uses a different programming algorithm. So if you want to use a flash part now we need new pc software or program it before its soldered to the board.

If you want an SMD EEPROM use an PLCC package it can be used in a socket so its not as big as the DIP package and it can be soldered with normal tools.

[quote author="pietja"]Maybe is an idea to use an 28C64 in a plcc package for better availability, and it can still be but in an smd socked.
