Link to the TR-7 Project! Link to the 10M SSB Project Blog Info . My grand plan for these modules The VFO A//B indicator and LSB/USB mode indicator, for example are similarly “pinned” to the Active VFO display, so if you move the Active VFO display to another screen location they will I was able to define the pins in the Arduino sketch (outside the library portion), however, I found that the processing time required increased substantially, so I left the VFO/RF generator for use in homebrew radio equipment such as direct conversion and superheterodyne receivers or ham transmitters. I assumed that the sketch that I had downloaded from Pete's blog was for a different OLED module. How execution of a sketch can be stopped? One option I can immediately think of is to simply make a for() I have just started with my Arduino Uno R3 and have now reached the stage where I would like to tidy up my sketchbook.
