I see that Digital Radio Mondiale is replacing analog radios in many countries. Can Julia be used in this DE9180 Demonstration and Prototyping Kit for the DRM1000 Broadcast Receiver Module | CMLMicro ? CMLMicro is using Python but it would be better to use Julia.
Are there any projects being done in Julia for DRM? I think they can help in E-education in remote areas of the world. How we can have better/cheaper DRM radios? DRM uses OFDM technology:
Can any Julia library be used for Digital Signal Processing of DRM Radio developed using DRM1000? Software Defined Radio tuner used in it is CMX918( 
costs <$15 ). If CMX918( costs <$1) signal output can be processed then it is easy to listen and receive DRM Radio 
services on laptop or smartphone. I am looking for a way to control DRM Radio using Julia.
What are you basing this conclusion on? If they’re using Python as a cheap interpreter to run code mostly compiled from other languages, then the current Julia implementation wouldn’t add anything notable except a bigger runtime. If they support MicroPython-related implementations for even lower overheads on limited devices, as implied by “connected PC or external µController,” then Julia or anything else carrying around an LLVM-based compiler are non-starters.
Looking at the documentation, you might be able to use LibSerialPort.jl to do what you like. I have found julia to be very useful if your use case requires custom things that standard python libraries do not provide. The code is very scalable while having good performance. In python, I found numba to be nice.
Yes, I think they are using Python just as interface to connect to DRM1000 using UART on laptop.
My question is that Can we do digital signal processing of CMX918 output data in Julia? This way we can do everything in Julia and listen Radio on laptop. DRM Radio can be used for E-learning.
Definitely plausible on a typical laptop given the right adapters, especially if you need to write a number-crunching routine from scratch. Still not sure how much work it would take to get a Julia interface working, and it’ll unlikely be maintained by the company.
Please try using LibSerialPort.jl and see how far you can go. I have used it before and should be able to help you if you get stuck (but also try using LLM first, the julia library is a thin wrapper around the C library so if the LLM is comfortable with the C Api, you could get by quicker).
I’m curious if there’s a serious use case for wrapping libserialport into a native julia style package (similar to the one I currently did for libsoundio), it shouldn’t take too much effort with a reference implementation on an LLM with some manual guidance/nudging
