[SOLVED] Newbie trying to get RFM69HCW working with ATMEGA328P

[Gaz83]

Hi, first post here. I followed the tutorial to get RFM69HCW working on a raspberry pi and have set one up as a gateway.

I am now trying to get the RFM69HCW working with an ATMEGA328P
I have checked the wiring and I have D0 going to PIN 2 of the ATMEGA328P

In MySensors sketch, do I need to change anything?

I have changed the following
// Enable and select radio type attached
//#define MY_RADIO_NRF24
//#define MY_RADIO_NRF5_ESB
#define MY_RADIO_RFM69
//#define MY_RADIO_RFM95

and I also added this

#define MY_RFM69_FREQUENCY RF69_433MHZ
#define MY_IS_RFM69HW

Welcome to the MySensors community @gaz83!
That looks good (except that I think you wrote "not" instead of "now)".

I have an RFM69HW running on a 328P. My code may help.
You didn't specify your clock rate but if it is a std board running at 3.3V it is probably 8Mhz.
The default DEBUG baud rate is 115k maybe a little too fast for the 8Mhz.
I lowered mine to 9600 because I can't read that fast anyway :)

#define MY_DEBUG
#define MY_BAUD_RATE (9600ul)

// === Hardware / MySensors Initialization ================
// ========================================================
#define MY_RADIO_RFM69
#define MY_RFM69_FREQUENCY RFM69_915MHZ
#include <MySensors.h>

// === Node Initialization ================================
// ========================================================
#define CHILD_ID 5
#define sensortype S_MULTIMETER

#define LEDPIN 9 //PB1 is pin 9 on ProMini
#define LED_TST A0
#define NODE_TXT "Counting_test_Node"  

uint8_t MyCount;
uint8_t ACK_Result;
uint8_t NACK_Count;

Had a look at your code and the only thing I spotted was in the frequency you had RFM69_915MHZ where as I was using RF69_433MHZ... I missed the M.

Tried again and still issues. Here is my monitor output, I am using the PassiveNode example sketch.

The tutorial doesn't mention anything about wiring the RS but I know on the adafruit version of RFM69HCW, you do need RS wired.

Solved the issue, I was using a custom PCB I had fabricated and the MOSI connection was not soldered properly.
