analogWrite DAC only once for each pinMode( ,OUTPUT)

Yup. Did the particle serial inspect which showed the following. Worth noting this data is coming back after I cycled power and the photon is stable. When I run that code straight out of programming mode I only have about 5-6 seconds until Magenta comes on and it resets itself.

This does not look like your user firmware was targeted at 0.5.1 :confused:

How does your device behave after flashing tinker?

particle flash --usb tinker

and what does inspect tell you then?

43

Oh, I didnā€™t realize that! Nice emoticon, I feel the same way. Thank you for your help (I really do appreciate it a lot)!

After flashing tinker I reprogrammed the Photon with that code (in the *.ino) file and it worked for 5-6 seconds, and then flashed magenta and restarted the device.

The script files below show the flashing of tinker, and then Particle Serial Inspect.

When I fresh up my device with these commands (each time enter DFU Mode before execution)

particle update
particle flash --usb tiker

I get this inpect output

BTW, does particle --version report 1.14.2?

45

Yes, it reports --version 1.14.2. I will run the Photon in DFU mode and execute the particle update and the particle flash to see if it changes revisions.
