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

Install depedencies:

On Debian/Ubuntu:

$ sudo apt install python3-setuptools python3-usb

(Optional) Install udev rules:

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

See examples/ sub-directory.

Requires adf435x to be installed.

Sets the output frequency to 1000MHz:

./adf435xctl --freq=1000

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

The firmware requires the following wiring:

First init/update all the sub-modules within the git repository:
```
$ git submodule update --init
```
Install AutoTools and the SDCC (Small Devices C Compiler).

On Debian/Ubuntu:
```
$ sudo apt install autoconf automake make sdcc
```
Build the firmware:
```
$ ./autogen.sh
$ ./configure
$ make
```
You will now have the firmware file fx2adf435xfw.ihx

Install cycfx2prog.

On Debian/Ubuntu:
```
$ sudo apt install cycfx2prog
```
Load the firware on to the Cypress FX2 with the following command:
```
$ cycfx2prog prg:./firmware/fx2/fx2adf435xfw.ihx
```
Run the firmware:
```
$ cycfx2prog run
```
The device will no renumerate as with the VID/PID 0456:b40d, as an Analog Devices board.

The firmware requires the following wiring:

First init/update all the sub-modules within the git repository:
```
$ git submodule update --init
```
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
```
Build libopencm3:
```
$ cd firmware/stm32/libopencm3
$ make
```
Build stm32f103adf435xfw:
```
$ cd ..
$ make
```

Run OpenOCD:

sudo openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg

Install the firmware:

telnet localhost 4444
