MODBUS_SET_BITS_FROM(3)

💖 MODBUS_SET_BITS_FROM_BYTES 💖

okay bestie, welcome to the libmodbus manual — specifically the page for modbus_set_bits_from_bytes. it's giving "tiny function, big responsibilities" and honestly? we're obsessed. let's get into it 🦋

---

✨ NAME ✨

modbus_set_bits_from_bytes — set so many bits from an array of bytes 💅

---

🌸 SYNOPSIS 🌸

void modbus_set_bits_from_bytes(uint8_t *dest, int index, unsigned int
nb_bits, const uint8_t *tab_byte);

---

🎀 DESCRIPTION 🎀

okay so here's the tea ☕ — modbus_set_bits_from_bytes shall set bits by reading an array of bytes. that's literally the whole vibe.

the way it works is: all the bits of the bytes read from the first position of the array tab_byte get written as bits into the dest array, starting at position index. so it's a little glow-up transformation — bytes go in, bits come out, everyone's thriving ✨🦋

no cap, it's a one-way trip from byte-land to bit-land and the index is just where you want the party to start in dest.

👑 RETURN VALUE 👑

there is no return values. none. zero. it's a void function, she gives nothing back and honestly? that's her main character energy 💅 periodt.
