Game won't start on Lipo

Post by dvagallery »

This is my first Adafruit project and I'm completely new so not sure what I'm doing wrong. I bought all parts and built the Neotrellis Game by the Ruiz Brothers (https://learn.adafruit.com/neotrellis-box-game). Everything works perfectly until I disconnect the USB and power the toggle switch off. Once I flip it back on, nothing happens. Just 2 blinking red lights. Can't get it to run again until I connect it back up to CircuitPython. Basically not running program after turning off. Please help. Thx!

What two blinking red lights?

Is your battery charged? Can you post a clear photo of the battery & its connection to the Feather?

Does the toggle switch work to power the project on/off with USB connected?

The Feather M0 blink twice when I turn the toggle switch back on. It is a new batter from you guys and did charge. Again, when I disconnect it from the USB, it does run on the battery. It's just when you power it off, it seems to "reboot" back to it's original state. With the USB connected, the toggle switch works to turn it off but not back on. Power does turn on but it goes back to blinking 2 red flashes. I have to hit "save" in MU in order for it to work again.

Bizarre. Have you rechecked your wiring and the soldering?

Triple checked. I also have an Feather m4. Should I try it on that? Would it be the same code?

It's worth trying to rule out or prove a problem with the feather. Same code.

Did notice this error when I looked at the Mu serial REPL. Not sure what it means. Don't have anything extra on it. Just the files it asks for.

Which board is this on? The M0 doesn't have much memory for running CircitPython. While it ran on the M0 when it was written ~4.5 years ago, CircuitPython and the libraries have grown since then.

This shouldn't be a problem on the Feather M4 Express.

I took the M0 apart and reinstalled everything and got that error. Just redid it all with the M4 and works perfectly. Ugh...

The SAMD51 (M4) chips have a lot more RAM than the SAMD21 (M0) chips, as well as generally being more powerful.
