  I pasted the code. Conversion from Uiflow to micropython works fine. def buttonB_wasPressed(): global hexstr, ppp, listbyte, aaa, HEXLIST, ooo, speed, acc, m, current, rcv_id, rcv_data if can.state() == 2: can.restart() can.send([16, 32, 48, 64, 80, 96, 112, 128], 0x7ff) screen.set_screen_bg_color(0x33ffff) label2.set_text(str(can.state())) There is a problem with can.send ().

  Hello @bmweller M5Stack has just released UIFlow 1.8.0. Unfortunately loading any old m5f files is broken in this release. We need to wait until M5Stack fixes that unfortunate regression. Thanks Felix

  500 mA is the limit on the 5V bus (if I recall correctly)

  Hello @m5stack good to know. Thank you for fixing the issue and letting us know. I appreciate it. (I myself cannot test the fix though as I don't have any M5Stack devices with that specific RTC chip.) Thanks Felix

  Hello @flex Sorry, I don't know if it's meant as workaround. M5Stack is not shy to use the term 'ultra low power' or 'very low power' for their products. And that is correct for several ICs used in M5Stack devices, like the ESP32 itself and yes, LoRaWan etc. Unfortunately however, in my experience, the way M5Stack integrates those low power ICs into their products very often isn't ideal to create a low power device. But to be fair, they also need to ensure, that stacking various modules to the older cores (Basic, Fire, etc.) and newer cores like M5Core2 do not destroy each other. So, it could very well be that the two diodes I mentioned before are a precaution. BTW: I myself asked this question a long time ago for M5Core2, but it never got an answer. Thanks Felix

  For those having the same issue, I fixed it by setting up latest M5Burner and driver on another PC...

  @slyderule What do you mean "Can't bind"? Have you tried reinstalling the firmware via M5Burner and using the new API code it generates to connect? If you are getting the red Disconnected message at the bottom then it could be just a server issue.

  Hello @hide4849 sorry, I am out of ideas and I don't have the CAN-bus unit so I cannot test myself. Good luck! Felix

  @m5stack This font maker for Aurdino is it correct? Not for uiflow and there is no way for Uiflow? At least only for numbers... You can add some big font only for numbers.

  I met just the same issues at the begining of use my Core2, but later I figured out that its just a problem of M5Burner and M5Stack project immaturity. Only UIFlow and Core2 factory test apps are compiled properly for Core2, other programs listed in M5Burner compiled for M5Stack Core and incompatible with Core2 (you can recompile they using sources and proper includes). Anyway after "bricking" the Core2 you can easly burn UIFlow or FactoryTest or another manualy compiled program through M5Burner or PlatformIO or standart ESP-IDF toolset from Espressif. Its not a real brick state, but just firmware incompatibility.

  Has anyone been able to drive two DC motors from the go plus 2 and core2 stack ? I am facing a problem at motor A which only rotates on values greater than 0 to max 127 , but goes not change direction on negative values . Though motor B works absolutely fine . I tested many motors each showed same behaviour at mot A port and worked fine at mot B port . Is my goplus2 damaged ?
