astropix-python-LFndry-Test

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

Installation

Requirements:

• Python >= 3.9
• packages: ftd2xx, async-timeout, bitstring
• D2XX Driver

$ git clone git@github.com:nic-str/astropix-python.git
$ cd astropix-python

# Create venv
$ python3 -m venv astropix-venv
$ source astropix-venv/bin/activate

# Install Requirements
$ pip install -r requirements.txt

Windows

D2XX Driver should be pre-installed.

Linux

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

Mac

See FTDI Mac OS X Installation Guide D2XX Driver section from page 10.

Example Usage

Upload the Firmware to FPGA Board
