Create an Arduino object and attach an I2C device object to it. Get a = arduino(); Use an address to create the I2C device connection. Get dev = device(a,'I2CAddress','0x55'); Read data from the I2C device with the precision of uint16. Get out = read(dev,1,'uint16') ...

Re: I2C read always get first byte Sun Sep 16, 2018 12:52 am 1) First, the message is being built when I change a variable instead in OnRequested. 2) In my Pi side, I send a i2cget with address (the Arduino get that address in OnReceived) and I store that in a global var...
(source: https://www.arduino.cc/en/Reference/Wire) Pro tip For devices that don't use de-facto standard register scheme you can use the low-level methods directly I2c._start(); I2c._sendAddress(slave_addr); I2c._sendByte(my_byte); I2c._stop(); For more details see the ...
