Command Summary
File Transfer Protocol
Once a bitmap or font file has been created and paired to its command it must be sent using a file
protocol developed specifically for Matrix Orbital displays. Once a file upload command has been sent
requesting a unique reference number and specifying the file size required, the display will respond
indicating whether it has enough room to save the file or not. As is the case throughout the upload
protocol, a response of 1 will indicate confirmation while an 8 corresponds to rejection and will
terminate the session.
Table 39: Upload Protocol Responses
Value
Action
Description
1
Acknowledged
Transfer successful, upload continues
8
Not Acknowledged
Transfer failed, abort upload
Once a file is confirmed to fit within the display, the upload will begin. A protocol is used here to ensure
each byte is uploaded successfully. After each byte is sent, the module will echo it back to the host. It
should then be checked against the value originally sent before a confirmation byte of 1 is returned. If
the transmitted and echoed values do not match the upload should be aborted by sending a value of 8
instead. The upload will continue in this manner as indicated by the examples below which utilize
familiar font and bitmap files.

It should be noted that the display has a timeout setting of 2.1 seconds before it resets to prevent
it
from hanging during the upload process. Upon reset, the values 254 and 212 will be returned to
indicate an error or lengthy delay has occurred in the upload process. If everything goes smoothly, the
protocol will end with the host transmitting a final confirmation byte and the font will be stored in the
display ready for any application.
