How to set up the MRF89XAM8A radio module with Arduino?

Projects General Guidance

Hi community,

I am wondering if anyone here has succeeded in setting up radio comms with the Microchip MRF89XAM8A radio module?

I have been struggling with it for a few days without much success and could use some constructive feedback.

The hardware setup:

A breadboard with a generic power supply plugin, an Arduino pro mini 3v3 edition, and the MRF89XAM8A radio module.

Pinout is based on the recommendations in the RadioHead library:

Arduino ----------- MRF89XAM9A
3.3V-----------VIN (3.3V in)
pin D9-----------/CSDAT (data chip select in)
SS pin D10----------/CSCON (configuration chip select in)
SCK pin D13----------SCK (SPI clock in)
MOSI pin D11----------SDI (SPI Data in)
MISO pin D12----------SDO (SPI data out)
D2-----------IRQ1 (Interrupt 1 output)
IRQ0 (Interrupt 0 output, not connected)
GND----------GND (ground in)

Library and code:

RadioHead RH_MRF89.h

If you have a working setup description with pinout, library and code samples, please do share it here, thank you.

Cheers,

Mike

Welcome!

Take a look at data sheets. your information is very sketchy. Posting an annotated schematic showing exactly how you wired it in place of the word salad would help. The first thing is the Vin does not work very well with 3V3. Reason below ~3.35 V the regulator can’t maintain 3.3 V out. Also post a link to the technical information on your Arduino it appears there is more then one variation of the pro mini.

Show or describe this.

Please post a link to the product page for the radio breakout board with the required supporting circuitry.

A photo of your setup, clearly showing the wiring, would be helpful, as would be a description of what you tried to do, and what happened when you tried.
