QUOTE(orko @ Jun 27 2007, 09:40 AM) Thank you orko Now i'm sure that the error resulted from the code loaded on the FPGA board , i checked the VHDL code it's OK. However when i changed the VHDL process that is resposible for this problem to have double the period, the Labview VI didn't work [i.e simulation stops and a timeout error showed up] thus, i have to change the Baud rate to fit the new values ....[period doubled then Baud rate should be Half of its value] now Labview back to life again and work But unfortunately with the same Problem . This is because when i used factor two to reduce the baud rate I -- at the same time -- doubled the period so they cancel each other and back to the same Problem. i don't know what Can i do ....??!! do you have any idea .... !! regards Sherif Farouk (",) -----------------

QUOTE(orko @ Jun 27 2007, 01:52 AM) I already made what you said but still no change anyway thank you for your help To illustrate the problem more and more When the analog pulsed signal is converted to digital and sent Over serial Port and then read again on the labview the read signal has half the period of the written wave (i.e double the frequency or double rate)

QUOTE(crelf @ Jun 24 2007, 06:07 AM) OK Thank you Crelf i already tried the loopBack test you suggested but when i write for example Ahmed i received Amd i don't know why regards, sherif farouk (",) Thank you both JackHamilton & JFM you really helped me to discover where's the problem but i don't know now why he pulse width of read message is half of the written on the port do you have any ideas for this behavior...?? thnx in advance Sherif Farouk (",) -----------------

I don't think LABVIEW is difficult You can simply search on the Name of the blocks you want especially if you know their Palettes and they are included in my reply, [bas el zaher Enak Mesh Taye2 el LABVIEW aslan] Anyway i'll do it for you but i think you should at least Understand How the serial Port interfaces with LABVIEW. OK KIMO Promise to read [3ashan Masla7tak walahi ana mesh far2aa ma3ayaa ana aslan el Code 3andi mesh moushkela] Don't forget to tell me your college ....

Thank you Eugen Graf for your efforts i know a little German so it's not too clear to me but i think it's so simple. Good work regards Sherif Farouk (",) -----------------
