STRUCT ES581_4_TX_CONF_MSG(9)

💖 struct es581_4_tx_conf_msg(9) 💖

okay so bestie, this is a page straight out of the Kernel API Manual, and it's all about one little struct. no cap, it's small, but it's iconic. let's get into it ✨

---

🌸 NAME 🌸

struct es581_4_tx_conf_msg — channel configuration. that's it, that's the whole vibe. it's the config struct for a channel 🎀

---

✨ SYNOPSIS ✨

here's the shape of it, exactly as it lives, no edits, i promise 🫶

struct es581_4_tx_conf_msg {
    __le32 bitrate;
    __le32 sample_point;
    __le32 samples_per_bit;
    __le32 bit_time;
    __le32 sjw;
    __le32 sync_edge;
    __le32 physical_layer;
    __le32 echo_mode;
    u8 channel_no;
 };

🦋 Members 🦋

okay now the main character energy — every single field, explained 💅

• bitrate — the bitrate. literally what it says 🍓
• sample_point — the sample point, and it's in percent, so the range is [0..100]. don't forget the percent part, it's giving important 📏
• samples_per_bit — type enum es58x_samples_per_bit. that's the vibe check on this one 👑
• bit_time — number of time quanta in one bit. quanta!! physics girlie behavior ⏱️
• sjw — Synchronization Jump Width. yes that's the actual name, and yes it abbreviates to sjw 🌈
• sync_edge — type enum es58x_sync_edge ⭐
• physical_layer — type enum es58x_physical_layer 🔥
• echo_mode — type enum es58x_echo_mode 🎀
• channel_no — channel number, and it starts from 1. do NOT confuse it with channed_idx of the ES58X FD, because that one starts from 0. two different indexes, two different starting points, and mixing them up is a whole situation 😭

fr fr, watch that channel_no vs channed_idx thing. one starts at 1, the other starts at 0. it's giving trap, and not the fun kind 💀
