Good morning everyone,

I was wondering if anyone has successfully ported Arduino library code to the micronutrients. I am looking at the si5351 library and want to use that with the mm but do not know where to start. Any suggestions/advice on how to tackle this please?

The library in question can be found here:

Thanks,

Hi Elia,

My approach (assuming you have a Micromite and a 5351 to experiment with) would be to try and talk directly to the 5351 via I2C from the mite.

You will need AN619 from the Si site to show you all the registers and their settings - it is a powerfull yet complex beast so I would start by trying to read the status register (R0 I think from the doco) then develop from that. The I2C examples in the back of the mite manual will give you an idea of how to talk to an I2C device.

I had a look through the Arduino code but as I am not at all proficient in C, I can't offer any advice here.

Cheers,
Doug.

... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it!

I was tempted and ordered a module to play with.
This website appears to have some useful information for me to read while I am waiting for the module to arrive.

How you layout the controlling software will depend a lot on how the device is going to be used.

Hi Doug, Jim,

Thank you so much for your responses. The QRP-Labs website has very good information including a link to AN619 plus some examples. I will get started on trying to get the Si5351 talking to the MM and hopefully will get somewhere 😁
