Details of motor rotation information transmit, temperature sensor information transmit, and receive
processing are as described below.
First, concerning motor rotation information transmit, as shown in “Figure 5-13 Motor rotation
information transmit”, there is the canSendTask01 function around Line 577 in MAIN.C. Only when the
motor is rotating, a message sent with CAN is created and the transmit function canSendData, which is a
CAN driver API, is invoked.

Concerning temperature sensor information transmit, as shown in “Figure 5-14 Temperature sensor
information transmit”, there is the canSendTask02 function around Line 601 in MAIN.C. Only when a
request for temperature sensor information is made, a message sent with CAN is created and the transmit
function canSendData, which is a CAN driver API, is invoked.
