Reprogramming DSTIKE with display SH1106

[harleyfrazee]

I have an application that would be wonderful if I could reprogram an inexpensive DSTIKE Deauther watch and utilize Arduino create. The project is a wrist watch that receives beam breaks and times a personal race.. I have the beam break software and the wiFi working well, but I can't seem to program the display of the unit. I'm told the display is an SH1106. Arduino Create doesn't support that driver (or I can't seem to make it work. Any hints or example code to support an ESP8266 processor and a SH1106 display would really help me out

SH1106

Have you checked out the links below?

I'm able to make the SH1106 and "D1 Mini" work.

I got a Makerfocus watch - the documentation says it uses the same components and the functionality works except for the display. Here's a picture of that

So next I tried a DStiKE Deauthor development board (shown below) I couldn't figure out which hardware to use for the Arduino

So, I tried the Lilygo watch and had the same issue as the DStike Deauthor

I include the code I write to the display that works only on the first watch. It should blink an H in the middle of the screen
