Kernel Module Voltage Graphs

The two graphs below use the same library a2d-helper.h. The cycle scan readings were saved for both the user mode program and the kernel module.

• user mode program
• uses a2d-helper.h
• c code

Data File

• a2d-powerscan-wave kernel module
• also uses a2d-helper.h
• c code
