hello,
I am trying to implement MLX90632 and currently stucked in calculation part. As discussed Float datatype in CYBT-343026 there is limitation of controller that it cannot hold fractional data. So trying to implement alternate options.
Already I am using lib called “Libfixmath” but there are some value above 5lakh so that library also cannot hold these data.
please suggest me fixed point library that can hold large data..
thanks and regards,
Neeraj Dhekale
