I have a few questions about the voxl-io library, and I would love if you could help me:
1.1. Missing ability to GPIO interrupt (or missing documentation?)
1.2. Missing ability to control of Pull Up/Down (Is the hardware exist to do so?, or missing documentation?)
1.3. Need clarification in the i2c api, can I write to a device without specifying a designated register?
For example in the smbus linux library: (https://www.kernel.org/doc/html/latest/i2c/smbus-protocol.html)
i2c_smbus_write_byte(...): Writes a single byte to a device
i2c_smbus_write_byte_data(...): Writes a single byte to a designated register on the device
