I bought a Sparkfun Photon Micro OLED Shield weeks ago, but that one didn’t work. (See Sparkfun Photon Micro OLED Shield - doesn’t work)
Thanks so much @Graham and @Sam , kindly sent me another one. I received it 2 days ago and gave it a go. I couldn’t believe that this one still didn’t work for me! It was so frustrating! I didn’t want to give up so I kept trying. I changed another Photon, another USB cable, tried both Particle Build and Particle Dev… no luck. I then went out and came back after couple hours, decided to try again. As soon as I plugged the power in and the Cloud connected, magic happened. It was working! I didn’t know why but it’s good that it was working.
The second day, when I came back from work, I plugged the power in straightaway. Nothing was changed, I didn’t flash any new firmware, didn’t change the USB cable, didn’t change the power source. But this time, it didn’t work, again. So I started trying again. This time, another USB cable seemed to do the trick. The screen finally started working, only with this USB cable. I carefully packed it up and didn’t feel good.
Well today, it didn’t work at all. Again, I tried everything I could do. I cannot get it worked.
I’m totally lost now and really need your help.
