Introduction

The LibTiePie library is a library for using TiePie engineering USB instruments through third party software.

Supported instruments

Library structure

LibTiePie maintains a Device list, containing all available supported devices. Possible devices are oscilloscopes, generators and I2C hosts. Instruments can contain multiple devices, e.g. the Handyscope HS5 contains an oscilloscope, a generator and an I2C host.

Devices can contain sub devices. E.g. devices contain trigger systems, oscilloscopes contain channels, channels contain channel trigger systems.

The LibTiePie library contains functions to control all aspects of the device list and the (sub) devices.

LibTiePie function name prefixes

All functions are prefixed, so it is easily determined where the function can be used for.

Using LibTiePie

When using LibTiePie, to control instruments and perform measurements, the following steps are required:

Initialize the library
Update the device list
Open the required device(s)
Setup the Oscilloscope
- Setup the oscilloscope channels
- Setup the oscilloscope timebase
- Setup the trigger (channels and device)
Setup the Generator
Start a measurement
Wait for the measurement to be ready
Retrieve the measured data
Close the device(s)
Exit the library

Error handling

On each function call a status flag is set, use LibGetLastStatus() to read the status flag. See also Status return codes.
