I am currently working on some code that i have acquired for a 7 line LED text scroller.
i have this currently working on an Uno for a single character display 7 lines by 5 cols.
Currently this uses pins 1 - 7 via PORTD 0-7.
I have modified the code so it will receive the string of text via serial communications, however i lose the bottom line of the array as its data pin is connected to pin 1 (tx)
What i would like to do is to move the serial communications to another pair of digital pins say 8 and 9 so i can still pass the string and keep the full display.
Can i simply use software serial to setup communications on those pins as every attempt at this so far has failed.
The attached image shows the current config of the neopixels - note the current draw is higher than the board can deliver, so a separate power supply would be needed. this is just for illustration only.
