The I
communications commands, Read and Write and Receive.
Read performs a combination Write then Read commands to the target device (refer to
the I
structure of the command is:
• Start bit (S_)
• Slave Address[W] – Enter the slave address of the device to communicate with.
• Word Address – Enter the word address
• Restart (RS),
• Slave Address[R] – The slave address with the write bit set will be automatically
• Byte Count – Enter the number of bytes to be read
• Stop bit (P_)
Write performs a write operation to the target device (refer to The I
reference in Section 4.1 “Introduction” above). The basic structure of the command
is:
• Start bit (S_)
• Slave Address[W] – Enter the slave address of the device to communicate with.
• Word Address – Enter the word address
• Data – Enter up to eight bytes of data
• Stop bit (P_)
The command will be logged in the Transactions window. A listing of the command
abbreviations is given in Table 4-2.
Receive issues a simple read command to the target device (refer to The I2C Specifi-
cation reference in Section 4.1 “Introduction” above). The basic structure of the com-
mand is:
• Start bit (S_)
• Slave Address[W] – Enter the slave address of the device to communicate with.
The write bit should be set to indicate a read operation.
• Byte Count – Enter the number of bytes to receive
• Stop bit (P_)
- Switch Off (not depressed) – blink LED1, LED2 off
- Switch ON (depressed) – blink LED2, LED1 off
The write bit should be cleared to indicate a write operation
entered when the Slave Address[W] has been entered
The write bit should be cleared to indicate a write operation.
