Python based lightweight cross-platform tool to control the GECCO System, based on ATLASPix3_SoftAndFirmware
To interact with the FTDI-Chip the ftd2xx package is used, which provides a wrapper around the proprietary D2XX driver.
The free pyftdi driver currently does not support the synchronous 245 FIFO mode.
For bit manipulation the bitstring package is used.
Features:
- Write ASIC config (SR and SPI)
- Configure Voltageboards (+offset cal)
- Configure Injectionboard
- Read/Write single registers
- SPI/QSPI Readout
- Import/export chip config from/to yaml
Work in progress:
- GUI
- Scans
Requirements:
- Python >= 3.9
- packages: ftd2xx, async-timeout, bitstring
- D2XX Driver

Install D2XX driver: Installation Guide
Check if VCP driver gets loaded:
sudo lsmod | grep -a "ftdi_sio"
If yes, create a rule e.g., 99-ftdi-nexys.rules in /etc/udev/rules.d/ with the following content to unbid the VCP driver and make the device accessible for non-root users:
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010",\
PROGRAM="/bin/sh -c '\
echo -n $id:1.0 > /sys/bus/usb/drivers/ftdi_sio/unbind;\
echo -n $id:1.1 > /sys/bus/usb/drivers/ftdi_sio/unbind\
'"
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010",\
MODE="0666"
Reload rules with:
sudo udevadm trigger
Create links to shared lib:
sudo ldconfig
