Thu, 04 Dec 2008 16:20:32 -0800 http://backend.userland.com/rss092 hi ajay,im working on data logger project. first im working at proteus .i cant find simulation model for adc0848 on proteus7.i need it badly.plz tell <noauthor@nospam.com> http://www.8051projects.net/forum-t1501.html hi rickey,im facing problem with adc0808 on proteus.it is not giving correct reading.actually i consulted mazide book.according to Mazide when we appl abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html you can try out with a similar kind of ADC, as this model is not there for simulation. see what properties are there in ADC0848 find a similar one wit Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html thankx for ur reply.i have done it using adc0808. abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html here are the files 1186743328_383_FT1501_data_logger.zip abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html can you show me the circuit that you've made? i want to see the circuit arrangement.As far as you told me, it must show 26 steps. rest i can only tell Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html ajay i have solved the problemi was making a big mistake abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html but i have solved by changing the circuitactually OUT1 is the MSB and i was taking it as LSB (very funny na). i didnt changed the program a little bi abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html I checked your cirucit, its perfectly fine..then i checked your program.. it has little mistake. The data you are getting from the ADC output will be Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html lol even i didn't check it.. and i thought you're not changing hex to decimal anyways happy it worked Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html abbas i cant see the circuit diagram how to open data logger.dnsfile which software u r using ۞ TPS ۞<tpsbpl@nospam.com> http://www.8051projects.net/forum-t1501.html hi ajay,hardware for this project is completed and also i have tested on hyper terminal.every thing working fine.now i want to make vb software for th abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html @ TPS: it can be opened by Proteus VSM Simulator software.Hi abbas,you can have this sample code for opening/sending/receiving data from the serial po Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html unable to attach more than 1 image abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html here is some notes for you..read carefully will give you good idea..Methods for transferring data to Excel from Visual Basicand a sample code.. Vb to Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html hi ajay!first im making logging software for only 1 channel.i have done logging to html file.here are samples of my software i will make for 8 channe abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html hi ajay,my project stopped working.i made pcb for it two times,and implemented one time on vero board.but it works fine for some time and after dat it abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html try changing thiswhile(*a!='\0'){sendChar(*a);a++;}towhile(*a){sendChar(*a++);}and tell me the results.. Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html nothing new happened wid your code.also when i bring adc in circuit...sendChar() method stops responding.wid adc in the circuit i get nothing . i abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html if you are saying that you have changed the circuit too.. then.. probably the programming mistake.. lets solve it.. paste your program again.. i want Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html hi Ajay!replying late coz i was out of town for some tafreeh.im posting c program and proteus file.only max232 and db9 are not included in this files abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html I checked your circuit... and i checked the code too.. it seems perfect to me.. nothing wrong.. I took a screenshot too.. take a look.. its working Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html i know dat its working on proteus.problem is dat it is not working on hardware.im using ez downloader for burning code.and if there was some problem w abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html Is the above code working with your circuit?I will check it on my controller and will tell you the results..By the way... did you check your circuit? Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html no the above code not works on my circuit.and it is confirmed that there is no problem in the circuit as i told u dat the circuit is working fine w abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html Hi.. abbas..one thing i am confused with.. you wanted to tell me that your friend's code is working on your controller board but your code which was w Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html yes my friend's code is working on my controller board but my code which was working few days back.. suddenly stopped workingand i still have those co abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html no not yet... i was just thinking about your program only.. and trying to understand what you really meant.. wait i try your send string program now.. Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html yes your serial program working on my controller board.. all i can say is.. check your connections or something Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html i will try it wid some different programmer board abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html hi ajay!here is my first program in assembly:) for this projecti just now tested it on proteus but it gets stuck after 30 seconds on proteus.i have n abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html well of course it will get stuck. the reason is.. you are calling the subroutines and you are not using the instruction "RET".so at the end of every s Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html i donno not able to attach file.. so just copying and pasting it here..

Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html yeah now it works u put ret at end of subroutine sendString.but y it was not working wid ljmp while1?????plz clarify becoz i have only 1 day knowled abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html you know why your controller stops working after 30sec?because of stack overflow..you are using acall.. that means call to a subroutine.. and in the s Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html now some different problem program tested on microcontroller board instead of proteus this time.but...i get reading to hyper terminal only if i p abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html i think i shud quit programming now and work wid my frends program i hav done every effort i can abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html there must be something you are missing.. well.. i donno what to say.. don't loose hope Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html hianyone knows how to generate crystal reports and how to attach them with vb?? abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html abbas it looks interesting ۞ TPS ۞<tpsbpl@nospam.com> http://www.8051projects.net/forum-t1501.html yeah looks really cool!!better than one binu is selling.. hope we can provide them with the source I strongly believe in Open Source things Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html here is what you were looking for hey.. abbas don't forget to share your project with Rickey's World..This one is for VB.net but it might be helpful Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1501.html hi Ajay, im adding GPRS mobile (T290i) to this project.wat i have to do is when mobile attached to circuit recieves a particular message i.e "s1" abbas1707<abbas@nospam.com> http://www.8051projects.net/forum-t1501.html hi abbas,if u have a empty pci slot u can get a pci based serial port ....if u r lucky u can even get two in one card..... it is simple to add th shyam<shyam@nospam.com> http://www.8051projects.net/forum-t1501.html wwwwwwwwwooooooooooowwwwwwwww!!!!!!! awesome people will do anything to make this project lol! ha ha ha....
