has anyone tried using the Chrome app usb API to communicate with a Spark Core?
I’m specifically looking for pointers on how to send either a “w” or “i” to the Spark Core and read its response.
I’ve tried using bulk, interrupt and control transfers with no success. my assumption was that I would need to send the character code for “i” or “w” to endpoint 3 using an “out” bulkTransfer and then retrieve the result with either an “in” intrerruptTransfer on endpoint 130 or an “in” bulkTransfer on endpoint 129.
any suggestions would be greatly appreciated.
