hummm...well yes that does help... so let me know what i need to do to get this chip...also will it do it both ways? or do i need 2 chips? thanks glen

sometimes people dont know what to search google for? i know i ask a question and with the responce i google it... for example i had a questoin about P/S converter.. someone suggested a UART.. now i had something to google....:) i think a better suggestion would be to search threads before posting...:) cheers glen

The baudrate for the display has options that can be set they said " Baud rates: 1200, 2400, 4800, 9600, 14,400, 19,200, 38,400, 57,600 and 115,200" so iam guessing it can go up to 115,200" The transcevers i got are. Baud Rates 1,200 to 38,400 baud Data Format Asynchronous - 7 data, even parity or 8 data, no parity; 1 stop bit so i guess i will try to use max at 38,400 dip is good... so you dont think the buffer problem with the 16550 would be a problem? Thanks glen.... iam going to have to put you on the special Thanks page :D

That sounds good... and i see the difference now i was looking at them and i came across this. iam guessing i would need the 16550A

" i did get to finish.... " i am going to look up some information on UARTS before i would ask to get one from you. i would not want you to wast time sending it and ect. if i am not sure if iam going to use it. cheers, glen

well before i say yes because i would like to try the UART, What device would i need to program them.. sorry i dont know anything about them, Also What is the difference between 2 wire, 3 wire, and parallel , serial connections? the reason i ask is because i was offered this chip by maxium http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3397/ln/ but iam not sure on this chip either.. also you had said the parallel to serial and serial to parallel converters would work but need a lot of ic support.. I thought it was one chip with intergrated and gates and flip flops? Well iam going to look up some info on the UART

hello agian too your too.. well i have never used an UART nor do i know how to program them.. is it hard? i have programed a pic chip? Also could i use something like this? http://www.national.com/ds/54/54F164A.pdf Which needs no programmming..... Also with this how would i find out if it is going to be fast enough? Thanks for your help..

of course i can and yes sorry feq..is frequency. this is the chip iam going to use. http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1335&dDocName=en010487 so i will use the analog output from the D/A converter as the input to that pic chip. This D/A... http://www.analog.com/en/prod/0%2C%2CAD5330%2C00.html So now iam looking for some way of getting a serial to digital converter.. which i was looking at what you had suggested... have not found anything yet...but i have not looked too hard either..Do you know of any free software that i could draw good skimatic of What i plan on doing...all i got is MS paint... once agian.. hope this helps.. if you are still confused let me know and ill try to explain it better. cheeers. glen

Thanks that is exactly what i was looking for. Now iam using that for my project and at the other end the anolog to feq converter is a pic chip... cant wait to program that :P then all i need is something that will turnon a relay when it gets a certin feq..a feq i can set? any ideals? thanks glen

Hello, This is what i was looking for and wondering if it is even possable. ok first i am sending data over a 9 pin connector. I got a chip that will take in an anolog signal and convert it to a feq. but my questions how can i get an anolog signal? i was thinking about using a D/A converter but the pin out of an 9 pin connector does not send data using 8 bits to were i could use the D/A...iam not sure how it sends it or does it send it all ready analog data?? ..really confused.. but any way does any one know how i could do this or what i could look for? thanks glen

o ya add this . int x; to the top of mine and it should work? and make sure x=.00 do( x=x+.01 MSComm1.Output = Chr(x) ) while(x<3000) is between the privent sub click() part and the end sub part..

What is it that you want to know? i rember in school using a thermister in a WS bridge connecting it to a A/D converter and getting a reading of temp with that..but it was not too good...

did you ever recive anything????

wow alun how did you help him....... i still dont konw what he wanted.... ???

ya ...what he said

quick question.... this is what i was told about the screen. why whould i need an power conditioning board? and what would be the purpose? i could just say yes i need it but then it would take longer iam guessing to get to me... do i really need one of these... thanks glen

****update**** well iam just waiting on some products before i do any more so thanks for your help and watch for this topic ;D ;D thanks, glen

so what if you look through a camera at a camera looking at a tv? ;D

http://www.omnexcontrols.com/files/Data_Sheets/RAD-ISM-2400-SET-UD.pdf these were scsi connection...i found the ones on my aka block diagram.. they are 9 pin connectors...and go about 2 miles? Has...

was it nextel? ...... i like them :)

its called a discount.. that is why it was cheaper and you buy a plan which you pay for.. a radio is a one time cost ...if you could buy a cell phone and never have to pay to use it well then i bet they would cost a lot more... btw....i once got a free phone too....along with that 3 yr contract for 84 dollars a month.... i rather own the IRS... cheers glen

not 100% sure ....... ok it is transmitted at a feq say 94.7 fm then when it reaches the radio there is a circuit inside which changes the feq to a lower feq so it can be played though speakers and head by the human ear. Now the higher the feq means the circuit inside has to me more complex which cost more. so why have a more complex circuit just to get an antenna little smaller? cheers, glen

you could always use some fishing string and tie one end to mouse and other end...to...your finger ;D

u can use an array. i have never used them in VB but i have in lots of other programming tools. or use a varable. like this x=.00 do( x=x+.01 MSComm1.Output = Chr(x) ) while(x<3000) %this will display it all... is that what you wanted? if you need the other part in it too do this. t=1 x=.00 do( x=x+.01 %this will keep adding .01 to x t=t++ % this will keep adding 1 to t Private Sub Command(t)_Click() %this will sub t for what # it's at MSComm1.Output = Chr(x) %this will sub x for what ever # it's at. End Sub ) while(x<3000) % it keeps doing this till x reaches 3000 or what ever % what ever number you put in here. like i said i never programmed in VB but this is how i would guess to do it... and this ishow i would do it in all other programming i have done.. cheers, glen
