I have one question, when you declare the buffer, how do you decide the size?

[@WinterCircuits]

Well, each type has a set size, so for example if you know for example you will receive two bytes of data, then youd declare the buffer size of two bytes. If I am unsure perhaps ill decide something arbitary and see how that goes.

[@pochuanpeng1729]

could you have a walkthrough for interfacing sht3x with STM32?

[@WinterCircuits]

Yes I can do

[@messedmushroom]

How can we adjust the code to decimal places are printed, not just .0000?

[@nandakhaorapapong9528]

Try %.2f as a format specifier.

Hallo i find it very good .Can you Upload the Code please

[@WinterCircuits]

Added it in the description.

[@alkhadizadiallo6362]

@@WinterCircuits thank you for the code but it does not work with I use the stm32F411RE and I modified the code but still it does not work. I would like to have your idea on it

@@alkhadizadiallo6362 Do you get an error or is it not communicating? Could you elaborate on the problem please, lets solve this!
