2.5 Where Do I Go From Here?

If everything appears to be working, we recommend the following sequence of action:

1.Run all of the sample programs described in Section 4.2 to get a basic familiarity with Dynamic C and the Jackrabbit’s capabilities.

2.For further development, refer to this Jackrabbit (BL1800) User’s Manual for details of the board’s hardware components.

A documentation icon should have been installed on your workstation’s desktop; click on it to reach the documentation menu. You can create a new desktop icon that points to default.htm in the docs folder in the Dynamic C installation folder.

3.For advanced development topics, refer to the Dynamic C User’s Manual, also in the online documentation set.

2.5.1 Real-Time Clock

If you plan to use the real-time clock functionality in your application, you will need to set the real-time clock. You may set the real-time clock using the SETRTCKB.C sample pro- gram from the Dynamic C SAMPLES\RTCLOCK folder. The RTC_TEST.C sample pro- gram in the Dynamic C SAMPLES\RTCLOCK folder provides additional examples of how to read and set the real-time clock

2.5.2 Technical Support

NOTE: If you purchased your Jackrabbit through a distributor or through a Rabbit partner, contact the distributor or partner first for technical support.

If there are any problems at this point:

•Use the Dynamic C Help menu to get further assistance with Dynamic C.

•Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/ and at www.rabbit.com/forums/.

•Use the Technical Support e-mail form at www.rabbit.com/support/.
