  let me know if you're having a group buy! and would it be possible to send the watch along any items we purchase in the espruino shop (with the christmas deal and all)

  Amazing! :D Can't wait until November when a local distributor rolls it out :)

• micro:bit v2

  Looks like they just announced it: https://microbit.org/new-microbit/

  It uses the nRF52833 and can use S140

  I wonder if current builds for nRF52840 would work (with some pin adjustments) ?

• Common accelerometer/magnetometer/etc API

  Device.getFeatures() would be really useful :) I'm guessing modules would then eventually be written to "add" themselves to the device list? And also be written to have a generic api to return raw values in addition to "cooked" values.

  Looks like everything's working:

  >require("Flash").getFree()
  =[
    { addr: 442368, length: 4096 },
    { addr: 1610612736, length: 16777216 }
   ]
  

  I used the common Arduino spi pins for the mapping:

    'SPIFLASH' : {
              'pin_cs' : 'D10', # cs
              'pin_mosi' : 'D11', # di
              'pin_miso' : 'D12', # do
              'pin_sck' : 'D13', # clk
              'size' : 8192*1024*2, # 16MB
              'memmap_base' : 0x60000000, # map into the address space (in software)
            },
  

  I wonder if we can just add in spiflash by default on the boards as a placeholder since spi can reuse the pins anyway (at least on the pixl, since it mimics the Arduino layout)? And maybe just pass in the cs pin when trying to use the Flash module just in case you'd want to reuse pin 10 for your own spi peripheral.

• Timeout on I2C Write BUSY - not all the time - SSD1306

  Adding additional 4.7k pullups don't seem to do anything different.

  Tried again with the HD44780 LCD Display, connecting it to 3v3 or VBAT still gets the timeout.

  I'll try and see if pullup resistors would work, maybe that's the culprit.

  Edit: looks like the I2C expander already has pullups: https://www.best-microcontroller-project­s.com/mcp23017.html

  Might have to break out an oscilloscope for this one :(

  Yeah, just checked with a spare SSD1306 - the above code works without issues.
