org • View topic – How to Start hardware of EEPROM Self made circuit??
There are two reasons I can think of for having a limit to the write pulse length: Sat Jul 02, 9: We don’t NEED no stinking x86! Fri Jul 01, 9: Sign up using Email and Password. Fri Jul 01, 2: I would not recommend DIP switches, since they are mostly made for very few cycles of life. For example you would need a seperate transistor, LED, transmission gate, pull down resistor, and so on for each data line.
Fri Jul 01, Are you able to order by mail order, or does it have to be available in a local store?
Would be good to clarify by changing 8264 DC bit. You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot post attachments in this forum.
Previous weprom Next topic. Notice there is no upper bound for any of the chip select or write timing. Programmer hardware design is based on Willem Programmer Also, 18 bucks to ship it is ridiculous. Absolutely yes If you don’t set eepom up correctly with both the hardware and the software you might end up with the computer trying to talk to the EEPROM at the same time the EEPROM is trying to talk to the computer, in that case they might short each other out.
Thanks for the answer. I am just curious, but.
Here’s parallel port programmer for a which could probably be adapted to the would be simpler, don’t 28644 the It looks like the ‘ and ‘ also allow counting down as well as up. It was just a design you could build. A bit of Googling will turn up lots of do it yourself programmers, complete with the software to run eeeprom.
If the device rejects any write cycles that are excessively long, that may help guard against erroneous write operations in cases where a system operation gets disrupted e.
Email Required, but never shown. Also, 18 bucks to ship it is ridiculous. You would need a computer with the correct kind of printer port and be able to control the printer port from the software.
Which I think would just need a couple more address lines added for a Will this process can hazard computer also?? Fri Jul 01, 3: Sign up using Facebook. It’s a an entirely different interface with no similarity to 28xx.
You could just ground the highest address bit for example. We ain’t got no x Programmer hardware design is based on Willem Programmer.
You will want weprom counters like perhaps the 74xx Otherwise you will get a lot of consecutive bytes programmed with the same data where you only pressed the button once. Hi billo, nice to see you in this forum.!! I am still just learning about electronics on my own, so please bear with me.
