SCPI Command Handler

[ztnel]

Description

SCPI (Standardized Command for Programmable Instruments) appears to be the primary choice for implementing a command wrapper for an embedded system integration test platform. The goal is to develop a scpi command handler which is capable of being memory configurable to support a variety of programmable and measurement endpoints. TCP/IP will be the interface medium for SCPI commands.

Input Stream -> String Parser -> Command Filtration -> Function Selection -> Parameter -> Function Execution -> Result / Return Code -> Output Stream

Verification

Ensure the system can respond to scpi commands sent out by general purpose open source libraries such as lxi-tools and PyVISA

Tasks

• SCPI string parser (support common SCPI syntax)
• Create memory map for command hierarchy
• Create function execution handlers with standardized error codes
