Example 2 with InterruptEntry

use of net.sourceforge.usbdm.peripheralDatabase.InterruptEntry in project usbdm-eclipse-plugins by podonoghue.

the class PeripheralWithState method modifyVectorTable.

 * Search vector table for handler and replace with class static method name

 * @param vectorTable  Vector table to search
 * @param irqVariable  Describes interrupt including: <br>
 *
 * <li> pattern      Pattern to match against vector table entry. <br>
 * This is a regex.  In addition the following substitutions are done before matching:
 *    <ul>
 *    <li> %i replaced with peripheral instance e.g. FTM1 => 1, PTA => A
 *    <li> %b replaced with peripheral base name e.g. FTM1 => = FTM
 *    <li> %c replaced with peripheral C++ base class name e.g. FTM1 => = Ftm
 *    <li> _IRQHandler is appended
 *    </ul>
 * <li> classHandler Name of class method to handle interrupt <br>
 * This is a regex substitution pattern.  In addition the following substitutions are done before matching:
 *    <ul>
 *    <li> %i replaced with peripheral instance e.g. FTM1 => 1, PTA => A
 *    <li> %b replaced with peripheral base name e.g. FTM1 => = FTM
 *    <li> %c replaced with peripheral C++ base class name e.g. FTM1 => = Ftm
 *    </ul>
 * Regex substitution patterns may also be used.
 *    <ul>
 *    <li> $n reference to regex group in pattern
 *    </ul>
 * </ul>
 * @param className  Base name of C peripheral class e.g. Ftm
