Control LimeSDR via SPI using Arduino MCU

Hello @TegwynTwmfatt,

So, promises from my side fulfilled.

Here you will find custom FPGA gateware, connection diagram as well as Arduino example sketch file on how to read/write LMS7002M registers.

Note please, that you have to use 5V to 3V3 voltage converters on outputs from Arduino. I’ve used 200 Ohm serial resistors for this purpose. Not very elegant way, but did the job. Tested with Arduino Duemilanove.

Let me know if you will have any questions.

Now is your turn :slight_smile:
