To read multiple bytes use read(fd, buf, count) See man 2 read, man 2 write for additional details. When you open the doc for the problem device and compare it to working and/or to the driver implementation you most likely will see a difference. #lfelc Linux I2C Subsystem Early implementations were from Gerd Knorr and Simon G. Vogl. The format for this command is as follows: I2cget [-f] [-y] 0 [MODE]. This can't be done with current i2cdump's 'i' mode because that just dumps all registers. (Note: the -r flag may interfere with write-only devices, but the default probing method does not work on the Beagle.) I am having a problem with the I2C driver for a Freescale p1022tw board. Programming and reading I2C memory devices is a common use case for the Aardvark I2C/SPI Host Adapter. Unfortunately this happens, there a kind of not standard protocols. In multiple readings for this device, it is returning always just the first byte value. Hi! It gives you a fully defined protocol for data transfer between multiple devices over two wires. I2C multi-byte read command not working while single byte reading works. If the mode parameter is omitted, i2cget defaults to a read byte data transaction, unless data-address is also omitted, in which case the default (and only valid) transaction is a single read byte. A safer approach would be to use a "Read Word" SMBus transaction instead, or an I2C Block Read transaction to read more than 2 bytes. Both these commands/methods require a second argument which will also be written to the SDA line following the read address. Warning. When you call wiringPiI2CSetup the return value is the standard Linux filehandle, say fd.

This will read 2 registers, the one that we give, and the following one. I traced things down into the FT232H commands and the _read_bytes(int) function is supposed to send: '\x20\x00\x00\x13\x00\x00' Which means, "Clock bytes in, 1 byte", "Clock bits out, 1 bit LOW" This should read one byte from the I2C bus and write a LOW ACK. This article focuses on how to take the information in an EEPROM datasheet and execute the commands in Control Center. It only takes a minute to sign up.
