MOTG-128 data sheet 3. software interface the MOTG-128 display module is a slave peripheral device and it provides bidirectional communications to a host controller via its spi interface. all communications between the host and the device occur over this spi interface. the protocol is simple and easy to implement. ? note: the host must initialise its spi port as the master and must meet the motg spi specifications outlined in the previous section. 3.1 command protocol C flow control the motg modules are slave devices and all communication and events must be initiated by the host. each command is made up of a sequence of data bytes. when a command is sent to the device and the operation is completed, it will always return a response. for a command that has no specific response the device will send back a single acknowledge byte called the ack (06hex) , in the case of success, or nak (15hex) , in the case of failure. commands having specific responses may send back varying numbers of bytes, depending upon the command and response. it will take the device a certain amount of time to respond, depending on the command type and the operation that has to be performed. if the motg device receives a command that it does not understand it will reply back with a negative acknowledge called the nak (15hex). since a command is only identified by its position in the sequence of data bytes sending incorrect data can result in wildly incorrect operation. ? 2011 4d systems www.4dsystems.com.au page 7 of 42
MOTG-128 data sheet 4. command set the command interface between the motg device and the host is via the serial interface. a handful of easy to learn commands provide complete access to all the available functions. the simplified command set also means that very low overheads are imposed on the host controller. commands and responses can be either single bytes or many bytes. all commands return a response, either an acknowledge or data. the command set is grouped into following sections: ? general commands ? graphics commands ? text commands each command set is described in detail in the following sections. ? separation characters such as commas ',' or spaces ' ' or brackets'(' ')' between bytes that are shown in the command/response syntax descriptors are purely for legibility purposes and must not be considered as part of any transmitted/received data unless specifically stated. ? 2011 4d systems www.4dsystems.com.au page 8 of 42 host motg command response
