hey guys, I am looking to add serial comms to my project without necessarily requiring the user to have a launchpad for its TUSB chip.
I understand that the USART module can do the transmission if I do a voltage shift up to the rs232 level, although what voltage does it need to be, +-5V +-12v. but with that said is it really a lost cause due to most computers not having serial ports anymore maybe I should aim for some usb scheme or something?
at the end of the day the project is a LED Nametag made from 3 small 8x8 matrices as a boosterpack for my micro Launchpad (battery powered, which is why the micro LP has the LiPoly charging chip in it, this project was the genesis of that one). and I want a user to be able to input the text to display without having to redownload a whole new program through CCS... like through hyperterminal or something but it is something I haven't played with
each matrix has aTLC59103 to drive its columns and all 3 matrices rows are wired together driven with a ULN2803 source driver driving the rows(500mA max with one channel on at a time / 24 columns = 20.8mA per LED max with all at 100%)
