RFM95 with nRF52840 issue

[Ryann98]

I have an nRF52840 feather and a Lora Wing RFM95W stacked on top of it. I am unable to run any of the example codes in the RadioHead library such as "Feather9x_TX" as they're failing to compile Looking at the code of the RadioHead library, there is ARDUINO_ARCH_NRF52 which makes you think it supports the NRF52 chips but it still tries to do the things and fails :

`C:\Users\Rayan\Documents\Arduino\libraries\RadioHead\RHHardwareSPI.cpp: In member function 'virtual void RHHardwareSPI::begin()': C:\Users\Rayan\Documents\Arduino\libraries\RadioHead\RHHardwareSPI.cpp:104:39: error: invalid conversion from 'uint8_t' {aka 'unsigned char'} to 'BitOrder' [-fpermissive] 104	_settings = SPISettings(frequency, bitOrder, dataMode);	^~~~

Sorry I think I forgot to mention something. The above error was obtained after I removed the code for board definitions and defined my own set of pins. If I keep the code in "Feather9x_TX" as it is, I get the following error:

Feather9x_TX:77:14: error: 'RFM95_CS' was not declared in this scope 77 | RH_RF95 rf95(RFM95_CS, RFM95_INT); | ^~~~~~~~ Feather9x_TX:77:24: error: 'RFM95_INT' was not declared in this scope 77 | RH_RF95 rf95(RFM95_CS, RFM95_INT); | ^~~~~~~~~ C:\Users\Rayan\Documents\Arduino\libraries\RadioHead\examples\feather\Feather9x_TX\Feather9x_TX.ino: In function 'void setup()': Feather9x_TX:81:11: error: 'RFM95_RST' was not declared in this scope 81 | pinMode(RFM95_RST, OUTPUT); | ^~~~~~~~~ exit status 1 'RFM95_CS' was not declared in this scope Seems like define(nRF52) is not working and hence why I had to define my own pins as I have them connected on my board and got the error mentioned in my previous comment ` #define RFM95_RST 11 // "A"

define RFM95_CS 10 // "B"

define RFM95_INT 9 // "C"

Thanks for reporting the issue, could you mind attaching the whole compile log as txt for analyzing since it includes lots of info such as BSP, libraries version in used. I will test this out shortly as well.

Hello Ha Thach, Thank you for your prompt response. Sure, please find attached the whole compile log and the code that I am using for testing. Compiling Error.txt Feather9x_TX_test2.txt

an fix is on the way https://github.com/adafruit/RadioHead/pull/66 , please wait until it is reviewed/merged then we could roll out a new release for the fix.
