BT and EE LimeSDR Hackathon

When EE, a tier 1 network operator, decided to back the LimeSDR crowdfunding campaign this was a clear indication of the scale of the opportunity at hand. And not simply for operators to reduce costs and extend coverage, but for wireless innovation to be democratised and the marketplace opened up to companies developing ground-breaking technology…

Welcome to FreeSRP

When we heard about Lukas Lao Beyer’s software-defined radio project, FreeSRP, it’s fair to say that we were suitably impressed. Creating an affordable SDR platform that covers 70MHz to 6GHz is no mean feat!

LimeSDR RISC-V Student Project Announced for GSoC 2017

We’re excited to announce that in partnership with the Free and Open Source Silicon Foundation, we will have a student working as part of Google Summer of Code on, not only the integration of a RISC-V softcore in the LimeSDR FPGA, but also adaptation to a FuSeSoC based flow. The RISC-V core will replace a…

Community growth: onwards and upwards!

As the Myriad-RF community continues to grow and develop we take a brief look back over the past four or so years, at some recent statistics, and how community and projects are evolving.

LimeSDR Workshop Materials Available

On 24th March we hosted a one day workshop in partnership with the BCS Open Source Specialist Group and Open Source Hardware User Group, that provided an introduction to software-defined radio and LimeSDR. Held at the BCS offices in central London, the event was free to attend and proved to be very popular, with participants…

LMS7002M Python package and VNA example

Back in June, during the LimeSDR crowdfunding campaign, one of the many great demos that we shared details of was a basic Vector Network Analyser (VNA). Since then we’ve understandably had quite a few requests to share the code and this was always the intention…

LimeSDR LuaRadio support and Arch Linux package

LuaRadio is a lightweight, embeddable flow graph signal processing framework for SDR and as the name suggests, it is written in the Lua language. It benefits from no external hard dependencies and a binary footprint of an impressively small <750KB, which even includes the LuaJIT just-in-time compiler.

LimeSDR configuration speed optimisation

Right from the outset the intention with LimeSDR has been to provide the very best performance and overall user experience, with a commitment to investing significant effort in engineering and striving to get the most out of the hardware platform.

A good example of this is the USB 3.0 interface and this is provided by a Cypress FX3 microcontroller, which is available in many different variants. One option would have been to select a device with a lower throughput on the interface used to transfer samples, but that incorporates an SPI core that would have made programming the LMS7002M transceiver far simpler. However, instead a higher throughput device was selected, that doesn’t have SPI but does have I2C.
