Is the enclosing element for data type definitions.

/component_viewer/typedefs/typedef

Define complex data types that may be used in read and readlist elements. This data type definition is used to read information from the target memory of the application. Optionally it may include also var elements that create temporary helper variables for calculations at the debugger level.

Parent Element	Element Chain
typedefs	/component_viewer/typedefs
Attributes	Description	Type	Use
name	Define the name of a data type. This name is used in read and readlist elements.	xs:anySimpleType	required
size	Expression that specifies the size (in [Bytes]) to read from target memory.	xs:anySimpleType	optional
info	Descriptive text with additional information (comment).	xs:anySimpleType	optional
import	Name of a symbol in the user application which is loaded into the debugger. The underlaying data type of this symbol is used to: recalculate the value of the attribute size of this typedef element. for member elements with no explicit attribute offset, the offset value of matching member is set. If the member is not part of the symbol in the user application the attribute offset value is set to -1. __Offset_of can be used to check this value. Example: Use the data type information of symbol tcb in source module main.c <typedef name="tcb_type" size="12" import="main.c/tcb"> // size is recalculated from symbol tcb <member name="type" type="uint8_t" offset="0"/> // offset not updated, because specified <member name="name" type="uint8_t" size="16" /> // offset updated, because not specified </typedef>	xs:string	optional
Child Element	Description	Type	Occurrence
member	Name of a member variable in target memory.	MemberType	0..*
var	Temporary variables for local calculations in component viewer.	VarType	0..*

Example: Using var

<typedefs>
  
  <!-- Structure reflecting an array -->
  <typedef name="TypeArray1" size="8">
    <member name="type_ref"      type="uint32_t"   offset="0"  info="Pointer to array"/>
    <member name="id1"           type="uint8_t"    offset="4"  info="Type ID"/>
    <member name="attr"          type="uint8_t"    offset="5"  info="Type Attribute"/>
    <var    name="idx"           type="uint32_t"               info="Index in array"/>
  </typedef>
  
  <!-- Helper variables for Stack-usage calculation -->
  <typedef name="TypeArray2" size="8">
     <var   name="XcurSP"        type="uint32_t"   value="0"/>
     <var   name="bSimpleStk"    type="int32_t"/>
   </typedef>
  
</typedefs>

Example: Using read

main.c file

struct MyComp_info_t {
  int version;             // component version
  int channels;            // number of communication channels available
  int buffersize;          // size of the communication buffer
};
 
struct MyComp_info_t MyComp_info;
 
void MyComp_initialize (void) {
  MyComp_info.version = 3;                         // Set information
  MyComp_info.channels = 1;
  MyComp_info.buffersize = sizeof(MyComp_data.buf);
}
