4.4.5 Example of changing communication speed

The procedure for changing the communication speed of Renesas Motor Workbench with the sample
software is shown below. See the Renesas Motor Workbench User's Manual for the values to change.
- Change the communication speed setting of the sample software (when the required communication
rate is 10 Mbps)
(1) Press the Clock button on the Main Window to change the value to 80,000,000
This value was calculated by multiplying the default 8,000,000 by 10
because the UART communication baud rate was changed from 1Mbps to 10Mbps.
(2) Select the COM of the connected kit in the COM of Connection
- Change the communication speed setting of Renesas Motor Workbench to connect
(1) Press the Clock button on the Main Window to change the value to 80,000,000
(2) Change the value of MTR_ICS_DECIMATION in r_mtr_ics.h to 1.
