Scalar Data Types

The following scalar data types are supported and can be used in read, typedef, and var elements. read and var also support arrays based on scalar data types.

Table with supported scalar types:

Data Type	Description
uint8_t	unsigned char (8-bit)
int8_t	signed char (8-bit)
uint16_t	unsigned short (16-bit)
int16_t	signed short (16-bit)
uint32_t	unsigned int (32-bit)
int32_t	signed int (32-bit)
uint64_t	unsigned long long (64-bit)
int64_t	signed long long (64-bit)
float	single precision floating number (32-bit)
double	double precision floating number (64-bit)

Code Example

<read name="main"        type="uint8_t"     symbol="main"    size="64"    const="1"  />
<var  name="ObjSum"      type="uint32_t"                                  value="0"  />
<var  name="i"           type="int32_t"                                   value="0"  />       <!-- helper -->
  
<!-- sum up object code bytes starting from main() with the given size in <read main>: -->
<list name="i" start="0" limit="main._count" >
   <calc>
      ObjSum += main[i];
   </calc>
</list>

Complex Data Types

Complex data types are defined using a typedef element and can be used in read, readlist, and var elements.

var and read define a single variable or array based on a data type.

readlist defines a list of variables or arrays. The first instance of <readlist name="var"> will define 'var', the following use of <readlist name="var"> will use the definition.
