I'm building a sensor using a Robotdyn Mega Pro board.
The pinout of this board is here:
My network uses RFM69 antennas.
My connections are:
Power is connected to 3.3v line. I know that Mega pins are 5v and in theory RFM69 are 3.3v, but I have more sensors installed in a similar setup with mini Pro 5v and Nano boards that work perfectly.
I have also tried two different radios to discard hardware issues.
On start my sketch shows:
106 !TSM:INIT:TSP FAIL
My concern is that pinout diagrams for "normal" Mega boards show that pin D2 is assigned to INT0, while the pinout for this board linked above indicates that pin D2 is assigned to INT4.
In view of this, I have tried adding the following defines with no success:
#define MY_RFM69_IRQ_PIN 2
#define MY_RFM69_IRQ_NUM 0
I have tried all numbers from 0 to 5 for MY_RFM69_IRQ_NUM.
I also tried pins 18 and 19. I can't use 20 and 21 since I'm using I2C comms.
No matter what I try, I'm still getting the same error.
I searched through the forum and on the inet with no success.
I'd really appreciate if someone could point me in the right direction... thanks!
