I simply cannot replace the sx1272/6 module with HopeRF RFM95W in my design (issue mentioned here in details) so I have decided to make a working end-node using an Arduino
This way I can be sure my HopeRF modules are working, and I can reverse engineering it with the CRO on SPI and take it from there.
Even though I have a fair bit of embedded programming experience and electronics design I still struggle with Arduinos . Can somebody forward me to an article or a how to on correctly wring an Arduino Uno to a HopeRF module so that would be my starting point?
I have looked into this one,
But honestly I am not sure how he is directly connecting the UNO to the HopeRF module without level shifting the 5v from UNO to 3.3 in HopeRF. The HopeRF absolute max is 3.7
After I have level shifted, I am getting the following error.
I am also aware of the lines responsible for this issue but the lack of break point and watch window in Arduino IDE is making it so hard to actually be able to see what values are returned for the Semtech Chip revision.
So I really need a simple guide to follow and make sure it is going to work.
The HopeRF module has been driving me crazy in the past couple of months as I had multiple attempts to make it work and it doesn't really want to. This would be a great help.
