    Serial to Parallel Output

    Oo.. You need to send some kind of code to the UART, so it'll perform as what you want. I though that part is called program the UART. Anyway, do you know anything about PC16550D?

    Serial to Parallel Output

    Hi out there.. Currently i need a serial in parallel out circuit in order to operate my circuit behind that. I need a circuit that is able to invert the incoming serial signal and remove the start and stop bits. I am using a MAX232 and PC16550D UART to do so. The problem i face is how to...

    Programmable Dot Matrix Display System

    Hi.. Currently i am at the stage of shifting serial bits into parallel bits. I am using an UART PC16550D to do the shifting. I have a few doubts. Besides taking care of the serial input pin and parallel output pins, what other pins should i included? ??? Here is a diagram of the chip...

    Programmable Dot Matrix Display System

    Cost forbid me from doing so. So i use software to replace those. This includes storing those ASCII symbols.

    Programmable Dot Matrix Display System

    Hi out there... ;) I have something to ask about my programming stuff. Currently i am using visual basic 6.0 to do my programming. What i want is like that: ::) Base on an ASCII character, my program will able to find the pattern that represent the character and display it on the dot matrix...

    Request for MAXIM MAX232 datasheet

    Oops...sorry ante..i am not questioning about your datasheet... Sorry... Anyway..i think MAX232 from texas and maxim will work the same. Thanks alot~!!

    Programmable Dot Matrix Display System

    Yup, what you said is what i wish to do with my serial data. At first i want to use a 8-bit serial shift register to do the shifting, but it is quite tedious and complicated due to the timing issue. So now i plan to go for UART. I think that is cheaper than microcontroller. ;D

    Programmable Dot Matrix Display System

    HI there... Currently i need to shift my serial data input from computer to parallel output data. At the same time, i need to have the start and stop bits being removed. So is there any suitable way to do so? Probably a UART? Is there any of that will perform what i need in the cheapest possible...

    Programmable Dot Matrix Display System

    Hie out there~! Currently im working on my final semester project called Programmable Dot Matrix Display System. I hope i can get some guidiance from here. My project will not include any microcontroller and PICs. :-\ Basically, my thing will work like this: User key in something in a...
