SPI Speed Optimisation, LuaRadio and Arch Linux

Receiving AX.25 with LuaRadio and LimeSDR

The engineering team are constantly striving to improve the overall performance and user experience of the LimeSDR platform, and in a blog post this week over on Myriad-RF, Andrew takes a look at a change in the way that SPI programming of the LMS7002M FPRF transceiver is handled, which has resulted in much faster read and write operations. What this means is that there is now a far more responsive user experience when tuning around bands — as a radio amateur or shortwave listener might do — and it’s also possible to support frequency agile applications.

In a second post this week Andrew also introduces support for LuaRadio, courtesy of its developer, Vanya Sergeev, who has added LimeSDR support to the lightweight, embeddable SDR framework. Which is great news for fans of the Lua language and embedded SDR developers alike! There’s good news for fans of Arch Linux too, as Vanya has also packaged the LimeSDR host driver for the Linux distribution which is famed for its eminently elegant simplicity and power user appeal.

Product Choices

$299

LimeSDR

The LimeSDR is based on Lime Microsystem’s latest generation of field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by the LimeSDR to all other devices.


$99

Acrylic Case

A layered acrylic case to protect your LimeSDR. Can be used with either USB Type A or micro USB Type B. Antenna not included - separate purchase available.


$599

LimeSDR with Aluminum Kit

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. This board comes with fancy aluminum casing. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a fancy Aluminum casing coated with high quality material, cables, and antennas for a quick set up.


$799

Ultimate LimeSDR With PCIe Interface

Start developing apps based on Lime Microsystem’s latest generation of field programmable RF transceiver technology. The board will be delivered with turnkey support for a diverse range of SDR ecosystem software, a powerful API and rapid prototyping environment. All the boards in this category will come with a PCIe interface, cables and Antennas for a quick set up.


$85

Four Antenna + Cable Pairs

Omni-directional antenna set, covering frequency ranges 800-960 MHz, 1710-2170 MHz, and 2400-2700 MHz. Includes U.FL to SMA cables.


$169

GPIO Board

This stackable expansion board for the LimeSDR provides individually settable, bi-directional level-shifted I/O for FPGA GPIO 0-7. Each I/O has a high-voltage and power Darlington drive stage suitable for inductive loads, such as coaxial relays. LimeSDR not included.


$79

Hacker Case

This custom acrylic case accommodates both a LimeSDR and a GPIO Board, and includes SMA connectors for all RF ports, two SMA connectors for clock I/O, and a 40 mm cooling fan. LimeSDR and GPIO Board not included.
