Understanding Dec At Addy
An explanation of the Dec At Addy conversion process, which translates hexadecimal values stored at specific ECU memory addresses into their decimal equivalents.
"Dec At Addy" refers to the decimal representation of a hexadecimal value stored at a specific memory address within the ECU. This conversion is essential when interpreting raw ROM data for tuning or diagnostic purposes.
Conversion Logic
To determine the decimal value, identify the hexadecimal byte located at the target memory address and convert it to base-10.
Example:
- Target Address:
1094h - Hex Value at Address:
FF - Decimal Equivalent:
255
Tip
Most scientific calculators or programming environments (such as Python or C++) can perform this conversion using the
int(value, 16)function.
Common Conversions
| Hexadecimal | Decimal |
|---|---|
| 00 | 0 |
| 0A | 10 |
| 64 | 100 |
| FF | 255 |
Important
Ensure you are referencing the correct memory bank or offset when reading values, as incorrect address targeting will result in erroneous data interpretation.
