 The Pmod CLS can communicate with the host board through the [[pmod:communication_protocols:spi|SPI]], [[pmod:communication_protocols:i2c|I²C]], and [[pmod:communication_protocols:uart|UART]] protocols.  The Pmod CLS can communicate with the host board through the [[pmod:communication_protocols:spi|SPI]], [[pmod:communication_protocols:i2c|I²C]], and [[pmod:communication_protocols:uart|UART]] protocols. 
  
-Through these protocol standards users are able to set the cursor location and send other instructions by sending escape sequences. An escape sequence is specified by first sending the escape character (0x1B) followed by a left square bracket ‘[‘ (0x5B), and then one or more numeric parameters followed by the command character for the specific command. Check out our [[reference:pmod:pmodcls:user-guide]] for a complete list of instruction commands or feel free to use our provided [[:reference:pmod:pmodcls:start#example_projects|example code]] in the Pmod CLS Resource Center.  {{ :pmod:pmod:cls:temp2.png?250|Pmod CLS Block Diagram}}+Through these protocol standards users are able to set the cursor location and send other instructions by sending escape sequences.
