I try to use atof() in MQX 4.1 but it seems it's not define there. Any idea how can I define it?
What Kinetis device are you using?
What development tool are you using?
I did my test with TWR-K70F120M using CW10.6.
The user_config.h header for this Kinetis device has the #define's for MQXCFG_ENABLE_FP and MQX_INCLUDE_FLOATING_POINT_IO set to "1".
I had to add "#include <stdlib.h>" at top of file. I've attached my example which started with the mqx/examples/lwadc project. Look for "//DES" to see what I have made enhancements.
I had to update the Properties for the Librarian to use c9x_noio Model.
My terminal output has following:
ADC Test for TWRK70F120M
f=1823.403442 1823.40344 1823.403400 1823.4034 sf=1823.4034
