WebA safer approach would be to use a "Read Word" SMBus transaction instead, or an I2C Block Read transaction to read more than 2 bytes. Set the internal pointer register of a 24C32 EEPROM at 7-bit address 0x53 on bus 9 (i2c-9) to 0x0000, then read the first 2 bytes from that EEPROM: # i2cset -y 9 0x53 0x00 0x00 ; i2cget -y 9 0x53 ; i2cget -y 9 ... WebI2C and SMBus fault codes ¶. These are returned as negative numbers from most calls, with zero or some positive number indicating a non-fault return. The specific numbers associated with these symbols differ between architectures, though most Linux systems use numbering. Note that the descriptions here are not exhaustive.

WebIntroduction to I2C and SMBus. ¶. I²C (pronounce: I squared C and written I2C in the kernel documentation) is a protocol developed by Philips.
