  The firmware is updated monthly but because of Chinese New Year things have been quite. A new firmware is coming out based on Micropython 1.7 but only a test version is available. As to pycharm, never heard of it.

  Yes, watchdog timer could be an idea. The same can be done with a normal timer and calling machine.reset() when it fires. However I was wondering if there was a more graceful way of handling this, e.g. interrupting just the hanging urequests.request() method and then continuing with the program without rebooting the whole device.

  Thanks a lot. This seems exactly what I was looking for. Command line is not a problem. Will try it.

  Hello @dclaar I don't think this has been documented yet - but I could be wrong. But consider this. I have multiple M5Stack (Gray, Basic, Fire) and even with the same brightness setting the actual brightness differs visibly. Thanks Felix

  @lukasmaximus Hey lukas, on which firmware version did you make this run? I am running it on a M5Core Basic and the unit reboots after the .wav was played once and I hit the button again. I have to uncomment: uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4) to avoid another error still I get the: "sd card not mounted" lcd print. Is there any chance to adapt this patch to a newer firmware version? I have also tried it on a Core2, but it doesn't seem to know any of the I2C modes which you defined. would be great to get this to work again and make/update custom uiflow blocks. Thanks in advance for your reply

  SD card unfortunately still does not run through! I get this error message when the SD card fails. [Errno 5] EIO I wonder what the problem is here? Sometimes it goes only 2 hours and sometimes up to 2 days. If I log nothing on the SD card, I can just write something on it even after 5 days and it goes. Just not in continuous use.

  Hello @shliao GPIO36 does not support internal software pull-ups. So if your hardware setup requires a pull-up, you'll need to add an external pull-up resistor. Excerpt from this documentation: GPIO34-39 can only be set as input mode and do not have software pullup or pulldown functions. BTW: your Python code is ok and returns 1 when I connect GPIO36 to 3.3 V. Thanks Felix

  Hi, In GRAY M5STACK unfortunatelly PortA is used for I2C to some internal chip. Sometime GPS not work on Grove Cable. Just connect GPS to 16RX <<< TX White 17TX >>> Rx Yellow And all start working with no problem. Example code from Arduino works if You add #define RX1 16 #define TX1 17 ... void setup() { M5.begin(); M5.Power.begin(); GPSRaw.begin(9600, SERIAL_8N1,RX1,TX1);

  If the M5 firmware is close to the upstream MicroPython, you can: import gc gc.mem_free() And it will print the available free memeory gc.collect() Will run the memory garbage collection to free up memory that is no longer being used. You can gc.collect() somewhere in your main loop to make sure memory is kept tidy. See the gc module page for more information https://docs.micropython.org/en/latest/library/gc.html?highlight=gc#module-gc

  You can always use sprites to get rid of flicker. It happens because you write to LCD in runtime which is slow. Try sprites; First, create a sprite and set the size. Then fill it in black to avoid overwriting text. disp_buffer = new TFT_eSprite(&M5.Lcd); disp_buffer->setSwapBytes(false); disp_buffer->createSprite(240, 135); disp_buffer->fillRect(0, 0, 240, 135, BLACK); Then write desired text and push it to screen. disp_buffer->drawString("This is some text", 0, 0, 2); disp_buffer->pushSprite(0, 0);
