Quick and simple: I have a MyFocuserPro2 on a Nano that was working fine, and after some mucking about with the wiring, I can't get the ASCOM driver to connect any more. Weirdly, when I plug into the Arduino with the serial monitor and issue a ":0#", I get a nice focus-position message back. ????

Had to lay this aside for awhile -- hey, eight months is a "while"! --, but your debugging suggestions helped a lot. I eventually figured out that the I2C address of the display I'm using was 0x3D. Sigh. Working like a champ now though! I elected to use the 2X font and trim the messages to fit so my old eyes can read it at 2AM. Thanks again!

I'll report back -- excellent debug tips, thanks! I do almost all of my work from a Mac, so I hardly ever run the Windows app. At a guess, suggestion #8 is the key, because I never ran the app to enable it. BTW, since I've got you on the line here, you also have my thanks for this wonderful project. Getting all of this firmware crammed onto an Arduino is reminiscent of the first Macintosh OS development effort -- amazing functionality given the hardware limitations! My hat is off to you.

Apologies if this is a FAQ, I could not find an answer elsewhere. I put together the solderless MyFocuserPro2 and compiled the firmware with the OLED option (OLEDDISPLAY 1 and USE_SSD1306 1 in focuserconfig.h). Got the focuser running (yay!) and the temperature probe working (yaaay!) and at one point the buttons too, though I may have a bad connection now (booo!). When I fire up the board, the display* shows nothing. The test program from AdaFruit works fine (e.g. ssd1306_128x64_spi), using the Adafruit_GFX.h...
