  Hi @kasperhvid, any luck on that? I was hoping to do the same but all I get is an obscure "ERROR" response back from the getVersion() method.

  Hi, and thanks for the quick reply and help. I checked without any device connected and got the same behavior. To try with the UIFlow firmware like suggested, can you please describe how on an Atom device I can make the firmware to execute the boot.py and main.py out of the flash, so I can use my tooling how described? It not worked until now. I can connect to the repl, but there is something running, even when I am in the (blue) usb programming mode. From where the UIFlow firmware executes? Can I put my stuff there with ampy? Thanks for the help again!

  Hello @leo-ninja-turtle the IR unit has two modes: NEC and GPIO. By default the IR unit is added in NEC mode, however the block ir_0 state is part of the GPIO mode - hence the error. Try switching the mode to GPIO by clicking on the IR unit and then use the Mode drop-down menu. Thanks Felix

  Hello @josephleeks according to the description of the M5GO Base Port the pins used for port C on M5Stack Fire are GPIO16 and GPIO17. Unfortunately those pins are already used internally for PSRAM. In other words, if I am not mistaken, port C on M5Stack Fire cannot be used. Thanks Felix

  No worries, hopefully m5stack people can consider enabling it for future production runs; i recon it would lower the threshold for some users.

  Hello @gunnm yes, that is my understanding from reading the datasheet. The I2C address can only be changed via hardware. Thanks Felix

  I mistakenly connected it wrong. It functions as a I2C keyb out of the box. I flashed it w/ the Arduino IDE to be a UART serial keyboad (i.e. terminal). Great! :)

  This issue was resolved. It was a simple misunderstanding of mine. "angle8.read_status" method was only for reading version and address. To read other registers, another angle8 unit method or normal I2C read work as expected. I realized I had been asking help to wrong people for almost three months, though they were also in M5Stack. I finally got the answer telling me it was my simple mistake.

  The Vcc on the "Grove" interface is actually stepped up from the 3.3V supply by a tiny SGM6603 chip (on a StickC-Plus). This chip can only supply about 1A, 1.5 absolute max. So this peripheral may or may not be suitable for all M5 devices.
