Software & Command Reference
Messages following the termination message will be considered as
standard CAN messages.
The host sends the buffer (see the SC Macro manual for the buffer
format), with a terminating CR message (length: 1) at the end of the
buffer, message after message. The messages are formatted as the
report messages, with a length of 8 or 4 bytes. Received numbers are
appended to the buffer (AR array).
It is recommended, although not a must, to follow the following guideline:
The CAN messages that download the buffer will be of 8 bytes (2
numbers) each except for the last message in case of odd number of
values to download. This is to optimize the download time.
The controller receives the CR message and terminates the buffer downloading
mode. The controller sends the OK prompt ('>') message to terminate the
download process.
Overflow
In case that the downloaded buffer overflowed the controller buffer (extra
numbers were ignored), the controller responds with the non OK prompt ('?>')
message to the terminating CR.
In all failure cases where the controller responds with '?>'message, it also set a
suitable value at EC, to identify the failure type:
EC_DOWNLOAD_OVERFLOW.
EC gets this value if the buffer is overflowed during downloading (trying to write
to AR[4001], for instance).
