27. write and read operation If the input TX DATA is empty the write operation is not performed If the Bytes to Read input is set to 0 the read operation is not performed If the TX Data array input has data then this VI starts with a write operation An I2C START bit is followed by an address byte the R W bit is automatically set or cleared by the firmware The TX DATA bytes are then transmitted followed with an I2C STOP command If the Bytes to Read input is set to a value other than zero a Read operation is performed An I2C START command is sent followed by an address byte with the R W bit set to R and then the requested number of bytes are received from the slave The operation is completed with an I2C STOP command All read bytes are responded to with an ACK except for the last byte which is responded to by a NAK There is no delay between the write operation and read operation Some devices require processing time before responses can be generated for example if you are writing to a memory location in the EEPROM you can not immediately read back the memory location without a small delay allowing the write cycle to complete Use the I2C scripting function if you need more control over delay timing when executing commands 3 3 3 I2C Simple VO Examples Several examples that use the 12C Simple VO Vl s can be found in the TIMS 0102 examples directories The first example Example _I2C read eeprom _memory vi is shown below Ra DATA EEPROM
