I want to connect my Arduino UNO to a serial device that once powered displays signature numbers. I want to then display those numbers on an LCD display. I have my 16x2 LCD wired correctly and it works fine even when I use the SerialDisplay example code from the library.
My questions are:
- Can I use a USB to TTL serial cable to connect the RX/TX pins of the serial device to the TX/RX pins of the arduino?
- The two numbers are more than 16 characters. How can I cut the numbers down and then display the two numbers on two seperate lines of the LCD display?
Let me know if I should provide further details.
