💖 MODBUS_GET_BYTE_FROM_BITS 💖

okay bestie, pull up a chair, we're reading a libmodbus Manual page together and honestly? it's a short one, we love that for us. this is MODBUS_GET_BYTE_FROM(3) and it's about scooping a lil byte out of a pile of bits. no cap, it's giving "tiny function, huge main character energy". ✨

🌸 NAME 🌸

modbus_get_byte_from_bits — get the value from many bits

🎀 SYNOPSIS 🎀

uint8_t modbus_get_byte_from_bits(const uint8_t *src, int index,
unsigned int nb_bits);

🦋 DESCRIPTION 🦋

so here's the tea. the modbus_get_byte_from_bits() function shall extract a value from many bits. all nb_bits bits from src at position index are gonna be read as one single value. that's it, that's the whole vibe. 💅

and if what you actually want is a full byte? set nb_bits to 8. periodt. 👑

⭐ RETURN VALUE ⭐

the function shall return a byte containing the bits read. that's your lil byte, go off. 🫶
