Use NODEBSTEP_CNT_U16 (= 65535) as the last argument in set ntc. Also put it in mdd too : Fixed on 2/11/2016 | ||||||||||||||||||||||||
Check the naming conventions for static functions and verify that usage of '_' is allowed in the function name : Doesn’t require any fix | ||||||||||||||||||||||||
NXTRFIXDPT_P8TOFLOAT_ULS_F32 in line nr 941 should be changed : Fixed on 2/11/2016 | ||||||||||||||||||||||||
line nr 942 - check for the consistency in the way array's are passed as arguments to interpolation function : Fixed on 2/11/2016 | ||||||||||||||||||||||||
Check if setting the NTC to passed in init is required as prepassing is done in periodic : Review comment rejected after discussing with function team | ||||||||||||||||||||||||
