OK so heres the situation;
I am scanning data from high tech laser scanners and outputting the data via a can bus etc, i have the ability to plug in an RS232 cable from a laptop and connect onto a PCB board with TX, RX, GND pinouts, then open up a terminal program, input my baud rate and parity etc..
i can then monitor the RX output in my terminal window.
to make this process easier i would like to use a smaller hardware version of this with an arduinio box.
basically i will have an arduinio, A screen and a power source and the RX and GND cable running to my working scanners.
can this be output on the screen with ease? and how would i edit the setup for baud rate and parity and bits etc without the need for coding onsite and laptops?
