Hi, I have been working on a 6502 computer, and was in need for video output. So i choose my Arduino Uno and was using the TVout Library. I came from the 6502.org forum, in need of help from the Arduino's community, I was wondering on how to use the TX and RX pins to communicate with a UART that i have... (MAX3100) That will eventually communicate with the 6502. And How should i program the Arduino Uno to display what the UART and MPU is sending it, Im trying to learn both the Arduino Language and 6502 ASM, And Im designing the Computer, So i have a lot on my plate...
If anyone has any idea on how to do this, I will be eternally grateful, and maybe this could help others who are trying to do the same thing as me. 
If this isnt the place for this question, then i dont know where else to go, because Id rather not look helpless...
