The first byte of an I2C transfer contains the slave address and the data direction. For some strange reason a few of my sensors are changing address (I wish I could figure this out too but not the subject of this post). mem_read (3, 0x42, 2) # read 3 bytes from memory of slave 0x42, # starting at address 2 in the slave i2c. If I attach to the serial port in the quick amount of time available while it is cyan, I just read “I2C Scanner Scannin” and then it drops. php?f=18&t=4742 It doesn’t respond to an Arduino I2C scan nor a Raspberry Pi I2C scan, i2cdetect. I've tried serveral I2C scanner but I always get the same feedback: I bought a cheap breakout for a temperature sensor and had no manual or other indication of which I2C address is used. But you can identify any address pins for your board using a loop. I did use only the scanner, but didn't try to actually communicate with the I²C device (an Oled display, in my case), so it's good to know that the communication itself works. Some homebrew I2C devices don't seem to use a This page (Configuring the Pi for I2C) was last updated on Aug 11, 2018. 8V FLASH memory, but flexible enough to I2C Devices and modules are widely available, and very popular in Arduino projects. t.
