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
