Software for RPi compatible shield for TDC-GPX2 chip
The TDC-GPX2 is a time-to-digital converter from ScioSense with up to 10ps timing accuracy. This software uses the linux kernel for GPIO and SPI-Bus to readout the GPX2 and calculate time intervals between signals. There is also the possibility of reading out the TDC using a FPGA which will then give much faster readout.

Files for building readout software for the TDC-GPX2 from ScioSense.
| Folder | Description |
|---|---|
| source/gpx2-raspi-readout-program | Contains a readout loop, buffer and calculations to measure time intervals between two signals with good accuracy. |
| source/spi | Folder containing gpx2 source files for making the tdc board library containing all options and an high level access for readout. |
| scripts | python script makes a histogram of the output. requires matplotlib |
| data | empty folder for output |
Readout via SPI:
Required:
- linux operating system (preferrably raspberry pi OS)
- up-to-date c++ compiler (C++17 compatible), tested with clang 11 and newer
How to build:
- requires cmake
- builds the gpx2 library and optionally the readout program
cd source
mkdir build
cd build
cmake ..
cmake --build .
to run the code:
/// outputs to stdout
./bin/readout
///redirect to file
./bin/readout > ../data/test_out.data
