#104858 - 8052 with a decoder - help! |
Hello It's Ed again ...
I have this circuit wired up http://people.morrisville.edu/~gonzal46/lab7.bmp Now, i have a decoder with a 373 latch on the higher 2k adress of the decoder, and the RAM on the lower 2K of the decoder. Now for my question, I am using basic (terminal), and having this wired up... my basic works when i play with the switches then it reads it somehow. Do i have a simple wireing problem? or can this not work ? ... Also to add that I disconnected with wire from the 74ls244's /OE to the /RD, but still have both /OE tied together..... and it detects the microcontroller 8052 all the time when i do this? can anyone with this knowledge help me please? Thank you!!! ALSO .. are there any jobs out there that i could work for ... i need a job :P .... |
