@gbastos
Fire does not have power saving function

Hello @ChuckInDallas

there is a POWER SWITCH at the bottom. See here. Make sure it is in the on position to charge and/or power M5Core.

Thanks

@Jules-Vern-Hacker-Man A linux version has been built for the CoreS3 so you may want to look at that but,
The cardputer uses a Microcrontroller not a computer so you will be struggling.

@figgalicous The desktop IDE hasn't been updated in a while. The Web version gets updated weekly.

Hello @cthulu

you want to check against ESP_SLEEP_WAKEUP_EXT0 as wake-up cause since the touch interrupt line (GPIO36) is setup using esp_sleep_enable_ext0_wakeup().

BTW: ESP_SLEEP_WAKEUP_TOUCHPAD is meant for an ESP32 feature where a GPIO can act as a touch sensor. See here (Which is different from the touch screen).

Thanks
Felix

Hello @myscho151

you could use an M5StickCPlus - see stock example here.

Thanks
Felix

I'm testing the ENVPro and M5Station for a video guide but between 30 mins and an hour the Station resets with the rolling error log:

E (2903049) mqtt_client: Error create mqtt task
E (2918550) mqtt_client: esp_mqtt_set_config(415): Memory exhausted
E (2918551) event: event_loop was NULL

A fatal error occurred. The crash dump printed below may be used to help
determine what caused it. If you are not already running the most recent
version of MicroPython, consider upgrading. New versions often fix bugs.

I've tried enabling gc (garbage collection) to clear the memory each loop but it make no difference and if you check out my code I don't have any MQTT function enabled!

I'm at a loss here and wondering if this is a firmware issue.

@mgrouch There is already 2 I2c extenders

@desmbr If you want data to remain visible after shutdown or sleep, you do as you have surmised have to trigger the Screen HV, write the data then shut down.
The fading without the set screen HV is normal.
