pyadf435x

pyadf435x is a suite of software and firmware for controlling the Analog Devices ADF435x series of wide-band RF synthesizers.

The software suite consists of the following components:

  • adf435x - A python library that can control the ADF4350/1 via various hardware interface back-ends.
  • adf435xctl - A command line tool to control the ADF4350/1 manually.
  • fx2adf435xfw - A firmware for the Cypress FX2 that replaces the proprietary firmware for the EVAL-ADF4351 board.
  • stm32adf435xfw - A similar firmware for the STM32F103.

It's also possible to use the Bus Pirate as the interface for the SPI communications, simply using the adf435x.interfaces.BusPirate class.

adf435x

Installation

  1. Install depedencies:

    On Debian/Ubuntu:

    $ sudo apt install python3-setuptools python3-usb
    
  2. Build the python module:

    $ python3 setup.py build
    
  3. Install the python module:

    $ sudo python3 setup.py install
    
  4. (Optional) Install udev rules:

    $ sudo cp contrib/z60_adf435x.rules /etc/udev/rules.d/
    

Usage

See examples/ sub-directory.

adf435xctl

Requires adf435x to be installed.

Usage Examples

Sets the output frequency to 1000MHz:

./adf435xctl --freq=1000

fx2adf435xfw

The Cypress FX2 firmware project controls the synthesizer over SPI by bit-banging the FX2's GPIOs.

The firmware requires the following wiring:

FX2 Pin ADF4350/1 Pin
PA0 LE
PA1 CLK
PA2 DAT

Building

  1. First init/update all the sub-modules within the git repository:

    $ git submodule update --init
    
  2. Install AutoTools and the SDCC (Small Devices C Compiler).

    On Debian/Ubuntu:

    $ sudo apt install autoconf automake make sdcc
    
  3. Build the firmware:

    $ ./autogen.sh
    $ ./configure
    $ make
    

    You will now have the firmware file fx2adf435xfw.ihx

Usage

  1. Install cycfx2prog.

    On Debian/Ubuntu:

    $ sudo apt install cycfx2prog
    
  2. Load the firware on to the Cypress FX2 with the following command:

    $ cycfx2prog prg:./firmware/fx2/fx2adf435xfw.ihx
    
  3. Run the firmware:

    $ cycfx2prog run
    

    The device will no renumerate as with the VID/PID 0456:b40d, as an Analog Devices board.

stm32adf435xfw

The firmware requires the following wiring:

STM32F103 Pin ADF4350/1 Pin
PA4 LE
PA5 CLK
PA7 DAT

Building & Installation

  1. First init/update all the sub-modules within the git repository:

    $ git submodule update --init
    
  2. Install GNU Make, OpenOCD, and ARM builds of GCC compiler and Newlib.

    On Debian/Ubuntu:

    sudo apt install gcc-arm-none-eabi libnewlib-arm-none-eabi make openocd
    
  3. Build libopencm3:

    $ cd firmware/stm32/libopencm3
    $ make
    
  4. Build stm32f103adf435xfw:

    $ cd ..
    $ make
    
  5. Run OpenOCD:

    sudo openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg
    
  6. Install the firmware:

    telnet localhost 4444
    
    > reset halt
    > flash write_image erase /path/to/stm32adf435xfw.bin 0x08000000
    > reset
