This project is a development of the project “Floating point display for UNO (V1)” which I posted on 23 May 2021.

Rather than using two ATtiny 861 devices to drive the display a single ATtiny1606 is used. Two applications are provided:


FP_display_V2 is a Studio 7 application, however the hex file is provided so that Studio 7 may not initially be needed.


A UNO template is also included which is an Arduino sketch and comes with the subroutines required to drive the 1606


For basic background information the reader is referred to version 1 of this project.

In particular programmers notepad is recommended for viewing template resources that Arduino cannot open.
