Nettet26. mar. 2014 · 5. If you pass an int32_t to a function that takes a float parameter by value, then there will be an implicit cast (type conversion). One caveat though is that an IEEE754 single precision float has less precision than a 32 bit int (it has approximately 24 bits of precision, versus 32 for an int32_t ), so you may lose some accuracy if you're ... Nettet首先,您可以将N uint8_t 打包到N / 2 uint16_t 个元素中。 uint8_t buffer [BUFFER_SIZE]; uint16_t mp 3 _stereo_buffer [BUFFER_SIZE / 2 ]; 然后,您需要知道您的数据是小端还是大端。 对于小端: for (i = 0; i < BUFFER_SIZE / 2; i++) { mp3_stereo_buffer [ i] = (uint16_t) (buffer [ i*2] (buffer [ i*2+1] << 8)); } 对于大端:

Nettet5. mai 2024 · int16_t measurePressureOnce (int32_t &result, uint8_t oversamplingRate); The library only reports the temperature as an integer. If you want to get the temperature as a float, you'll need to define, and implement, an overload that does what you want (return the temperature as a float).
