I need an arduino code for MS5611 GY63 sensor with its registrations and without using the library. How can I find it?
If you want it written for you , try "Jobs and Paid Consultancy".
Why don't you want to use a library?
Because time is an important issue for me and every millisecond matters in my project. So to save time I'm going to not use the library.
Use a faster processor and the library.
What is your project that requires fast sampling?
I assume you have looked at the specs for the 5611, it looks a 1ms sample rate is possible.
