UNIT Libraries: Custom In-Circuit Test Applications

OSBDM includes a simple interface DLL (OSDLL). PEmicro’s UNIT Interface Library Routines extend the functionality available to OSBDM and allow the user to create a Windows application which can fully control the execution of an embedded processor via one of PEmicro’s hardware interfaces. During the development and production phases of the product cycle, PEmicro's UNIT DLLs will allow you to control interface hardware such as Multilink debug probes or Cyclone programmers.

The PC-based application can peek and poke memory, peripherals, and other resources of the embedded processor through the debug port. Applications can use this capability to perform tests of the target hardware, calculate target calibration data, or simply be a way to develop a totally custom application which controls the target via debug mode. The advantage of using debug mode is that the processor doesn’t need to be running application code or even to be programmed for the PC application to fully exercise the processor’s capabilities.

As a code example, a C code snippet for testing the address lines of an external RAM with the UNIT libraries can be seen here :
