'NAN' error running in Energia

[roboflank]

Am trying to run the program in energia and am getting the following error. BME_280_I2C_Test:78: error: 'NAN' was not declared in this scope exit status 1 'NAN' was not declared in this scope.

am using the i2c code example

I've not used Energia but I do use this in PlatformIO and it works fine.

Have you tried it in an another IDE?

What platform (MCU) are you building for?

denzelwamburu,

NaN (not a number) is a C++ 99/11 construct. Do you have the capability in Energia to specify using the C++ 11 compiler? If not you may need to define NAN in the BME280 file as well as the function isnan();

You can put something along the lines of:

define NAN 1e+30 / _HUGE_ENUF/

define isnan(n) n == float(NAN)

in the top of your BME280.cpp file.

Hi @finitespace , let me look at it tomorrow and give you the feedback. Thanks.

@finitespace Where exactly should this be placed? Putting it on the define sections of BME280.cpp doesn't solve the issue.

At the top of the BME280.cpp file should work.
