I am further developing one of my projects and i am running out of I/O Ports, I am using a Pic 16F887 with :- 9 x analouge inputs on ports B and E , 1 x Lcd Display on port D Digital Inputs on port A Digital outputs on port C I now wish to add coms to this project but with no spare ports was thinkin...

can anybody advise is flowcode 64 bit compatable ?

as i am getting a new pc which has win 7 home 64bit installed onto it

steve

ok thanks for that i will make one of my own

steve

Is there a E Block pcb to simulate analougue inputs ?

I.E. 8 x Pots

Steve

Think i Know where i went wrong now , port B can be used and configured for "in system programming" I.E Pick kit2 is that correct ?
and i have now turned that off .

Steve

Thanks for that turning of LVP did the trick

steve

i am using EB006 With a EB016

have made the following conections :-

D4 - Pin 1
D5 - pin 2
D6 - Pin 3
D7 - Pin 4
RS - Pin 5
/E - Pin 6

Just having some problems with this dispaly at the moment if anybody can point me in the right direction my display just shows 4 lines of squares - which reading on here indicates it hasn't started correctley, bit at a loss checked my wiring and all seams ok, attached data sheets and test flow code ...

Thanks for that, Is there any differance as that manual is for a V7 pcb mine is a V6.

i can see some differances ie scope and lcd and some other minor bits
the idc headers are they the same ?

steve

Is there any infomation on the pin headers on this pcb ( J5 , J24 )
Are these connected the pic chips pins or are they used for somthing else ?
Is there any prototype boards that plug onto these ?

can anybody please advise ?

steve

Thanks for that,

I am using V3.6.11.53 Pro

http://datasheets.maxim-ic.com/en/ds/MAX253.pdf

i have built circuit on page 6 and currantly exprimenting with it

Hope this is some use
