Add support for nRF52840 #259

Hi Sandeep,

is there a chance your library already works with the nRF52840?

Would love to use it with https://www.adafruit.com/product/4062

Kind regards, Thomas

Since the underlying API and peripherals are the same for the '832 and '840, you can supercharge your older nRF52832 projects with the same exact code, with a single recompile!

I'm not sure this qualifies as an issue, this is a question. I don't have this chip to experiment with, so I can't help you out. Were you able to use the library? Looks like it should work, right?

I'm new to this BLE stuff, maybe you are too?

Unfortunately it looks like this library does not work on the nRF52840. I receive this error while compiling:

Arduino: 1.8.9 (Mac OS X), Board: "SparkFun Pro nRF52840 Mini, s140 6.1.1 r0, Level 0 (Release)"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I thought it would be a worth a shot to edit hal_platform.h, thinking maybe just a few lines would needed:

#if defined (__AVR__) || defined(__SAM3X8E__) || defined(__SAMD21G18A__) || defined(__MK20DX128__) || defined(__MK20DX256__) || defined(__MKL26Z64__)

I tried to edit out all of the #if defined statements and just run the first block without any if's but the resulting code halts the device.

Then I found this commit for when the nRF52832 was added, so perhaps something like that will be needed for the nRF52840:
