In the example above, the servo's maximum speed will be set to 45rpm. When the servo is powered on (or after a reset), the CSR value is used. Note that CSD and CSR are effectively the same, but allow the user to specify the speed in either unit. The last command (either CSR or CSD) received is what the servo uses for that session.<div class="wikimodel-emptyline"></div> 858 +</div></div> 859 +{{/html}} 679 679 680 -This command allows you to control when the RGB LED will blink the user set color (see [[16.
