DDC Reference Sample Code : bcdemo_python_gui   Download 

This sample demonstrates using DDC's AceXtreme SDK in a python GUI script.

1. Overview

• The sample creates two BC->RT messages and two RT->BC messages and schedules them in two minor frames of 100ms each.
• It reads the BC host buffer using aceBCGetHBufMsgDecoded in a background thread and displays the messages in text edits.
• It provides an option to choose the Bus (A or B) on which the messages will be transmitted.
• It provides an option to enable message retry. If enabled, retry occurs once on the alternate bus.
• It demonstrates the aceBCDataBlkWrite API to update data for BC->RT messages.
